What To Do If You Hear Electrical Humming Sound In Wall?

Posted on July 7, 2020 | by K Hopkins

humming No one likes to experience mysteries in their own home. When it comes to hearing a humming sound, it can be both confusing and even as terrifying as a scene from a horror movie.

Humming sounds can almost seem like they are coming from everywhere in the walls or nowhere in particular. But the fact is, if you have heard an electrical humming sound more than once, then it’s likely there and some electrical component is to blame.

We will discuss some possible causes of an electrical humming sound in the walls and what you can do about them. It’s also important to know that in most cases the electrical humming sound can be a warning sign of other problems.

Mains Hum

The mains hum is either a humming or buzzing sound made by electrical wiring or equipment. The sounds occur at 60 hertz (for humming) and 120-180 hertz (for buzzing sounds). They are common with large appliances built with a motor. A good example is a refrigerator. Also, a magnetic field from outside the home can create and increase a mains hum in your audio systems. A mains hum is normal and harmless unless the hum becomes a loud buzzing sound. When this happens, you should contact your electrical technician.

Circuit Breaker

There are a few reasons why a circuit breaker may cause a humming or buzzing sound in your electric system. These include an overload of current. When a circuit breaker conducts more electricity than it can normally handle, it should shut off. When it fails to automatically shut off the current overload develops an audible buzzing sound. The solution is to turn off the electricity to your home and replace the breaker. Improper or incorrect wiring to a circuit breaker can also lead to buzzing sounds.

Wiring Problems

If your electrical wiring is the source of the electrical hum within the walls, it could be from a wide range of causes. Only an electrical technician can inspect this and point out the specific source of the buzzing sound. An example of sources of buzzing sounds due to wiring problems are improperly grounded wires.

Light Fixtures

A light fixture can make a humming or buzzing sound if the bulb is faulty or being used on a dimmer. Sometimes the fixture type is also to blame. Fluorescent light fixtures are also known for often making humming sounds. You can fix this problem by changing the bulb or fixture. If the sound persists, then call an expert to fix the problem.

Since a humming sound could be an indicator of other issues in your electrical system, it’s best to call an electrician when you notice these sounds. The electrician can better identify where your electrical hum is coming from and why. They can also fix the problem.

Avoid taking up fixing the electrical hum in the walls as a DIY project to avoid accidents or harm to life and property,

Wiring For the Future: Audio & Video

Posted on July 2, 2020 | by K Hopkins

For your home wiring system, there is such a thing as pre-wiring or wiring for the future. This simply means applying pre-wiring tips that may become vital in the future for adding categories like audio, video, home security, network & Wifi, cable, satellite, and internet.

In many cases, homeowners who install home wiring themselves or the technicians they hire neglect pre-wiring for the future and this can cause difficulty later on. Pre-wiring is important to do the heavy lifting in your home whenever you need it.

Here are some tips on how to hire a house for the future. If you won’t be carrying out the project, these tips let you know what to look out for with your electrical contractor.

Cover any exposed wiring

In wiring a house, most professional technicians aim to make the system smooth and neat. If you are lucky enough to have this professional approach, that’s great. But with or without this, you can take an extra step to cover any exposed wiring in your home wiring system. Wrap the wiring in plastic bags and hold them firm with a tape. This protects your wiring as other contractors work around the home.

Use low voltage boxes when you can

Although high voltage boxes seem more popular, low voltage boxes are ideal for installing volume controls or when you need to run HDMI cables. They are a more convenient option and suitable for AV wall plates. You should install them where possible.

Install a speaker wire

Good sound is a thing of excitement for homeowners. Audio or speaker systems can be installed in the future easily and affordably by running 4-conductor speaker wire. A 4-conductor wire differs from a 2-conductor wire as it has four separate wires that give you room for up to two speakers. Besides running this wire for whole-house speaker systems, you can keep volume controls in mind too.

Have backup

For modern home theaters, HDMI is the standard connection often used. However, some not so pleasant experiences can show you that it’s always best to have a backup. An HDMI house wiring for the future can come up with issues like not working and that just defeats the whole aim of pre-wiring. The solution is to run two CAT6 cables along with the HDMI cables as a backup for future use.

Install conduits

Cable conduits are not the same as electrical conduits and they often come in handy for running speaker wires, network cables, and cable wires. Install conduits during construction and terminate them into junction boxes. Cover them with faceplates and that’s the end of that until they are needed.

How about going wireless?

There’s nothing wrong with a plan to go wireless in the future. While this is great, wired connections are often faster and suitable for high-traffic applications. To ensure you can enjoy the speed of wired connections and use of applications like Ultra HD use wired connections such as CAT6 or Category 5e for your future proof home wiring.

Posted on April 30, 2020 | by K Hopkins

electrician performing a house rewire House rewiring is a tough project. It is disruptive and demanding of funds and electrical experience. The answer to if you need an electrician for a house rewire is yes.

An electrician is the technician that determines whether you need a house rewire. But after this, many homeowners prefer to consider making a house rewire a DIY project. It’s only possible to do this if you have the knowledge and experience with electrical service.

Read on as we discuss the reasons why you need an electrician for a house rewire and other tips like the steps to take to rewire your home with or without an electrical technician.

Why you need an electrician for a house rewire

Statistics show that the average American homeowner has 9 unfinished projects on their to-do list. 55% of these homeowners will attempt to DIY the projects and only 31% of these end successfully.

While DIY culture is booming, it’s important to remember that there are several factors involved in projects like a home rewire. For example, safety precautions, appropriate materials, building codes, permits, and more.

DIY is risky in many ways. It’s risky to your health and life as well as that of others and your property. Electrical work is dangerous business and without the right precautions, experience, or knowledge shocks, electrocution, and even fires can occur.

Most electrical projects like a home rewire usually require permits that ensure safety protocols and codes are being followed. Performing such electrical work without a permit is against the law and comes with legal consequences. Also, if someone in the home should get hurt from such improper work, you could be persecuted.

Hiring a professional electrician for a home rewire guarantees your electrical safety and efficiency. It is also cheaper and compliant in the long run.

Tips for safely rewiring your house

Find out if you need to get a permit and do so.
Carry out an inventory to know the materials you need for the project.
Consider any additions you would like.
Create a plan that shows what will be done and when it will be completed, especially when working with an electrician.
Avoid damaging the existing infrastructure.
Hire an electrician familiar with working on older or existing buildings.

Stages of a house rewire

A house rewiring project usually takes two distinct stages. The first stage involves the circuits, wiring, cabling, and back boxes replacement.

The second stage involves light fittings, faceplates, and sockets installation.

How often should you rewire your home?

Unlike regular repairs and replacements, a house rewire is hardly needed often. There is no specific timeframe for rewiring you home as electrical systems have a life span that depends on factors like use. If your home is over 25 years old or up to, it will benefit from a rewiring project or updating.

Relocating a 220 Volt Outlet in Los Angeles

Posted on April 13, 2020 | by K Hopkins

220 volt outlet A 220-volt outlet is the most powerful outlet in the home. It is built for power-demanding appliances, like ovens, dryers, and more. You can identify 220-volt outlets as outlets that are larger and different-looking than others. They usually have either 3 prong or 4 prong holes.

If you are renovating, remodeling, or moving any of these power-demanding appliances, you would have to move or install new 220-volt outlets to serve them.

Relocating or installing a new 220-volt outlet is always ideal because it sets the outlet behind the appliance, giving the room a clean look. It also helps to eliminate dangerous situations from using electrical extension cords.

Use the following steps to relocate your 220-volt outlet.

Safety first.
Before you get started with the relocation, shut off the power to the area of appliances. Next, take out the outlet cover and remove the outlet from the box. You can use an electrical tester to confirm that there is no power in the outlet. If possible, let others in the home know you will be working with electricity and the power has to remain off till you are done. Try to use rubber-handed tools and even a high-voltage glove to be sure of safety.
Choose and prep your new location
Choose the new location of the appliance and mark out the spot for the outlet on the wall in that spot. Cut open the drywall using the same dimensions as the existing outlet.
Remove the wires
Run the wires from the existing location to the new one. Ensure you use a stud finder to identify the stud where the outlet will be mounted.
Mount the outlet
Cut a new wire and run it from the old location to the new one. Then cut two inches of sheathing from the ends of the wire. Pull off half-inch of insulation from the black, red, and white leads on both ends. Nail the gang box for the outlet to the stud. Connect the wires that go into the old outlet’s gang box. Cover each with a wire nut and electrical tape. Run the opposite end of the new wire into the gang box, leaving up to 8 inches of wire coming in. Connect the black and red wires to the positive terminals and white wire to the negative terminals. Attach the mud rings to the gang box and slide the outlet in. Make the connection to the mud ring, place the new cover on the outlet, and screw in.

You can use drywall patches to patch the old outlet location.

Before using the outlet you can reach out to an electrician to inspect the installation for safety reasons. You can also contact us for further inquiries.

Rewiring a Los Angeles House Room by Room

Posted on April 8, 2020 | by K Hopkins

los angeles house rewire by electrician Deciding to rewire your home does not come easily, and there’s no surprise why. Aside from the fact that home rewiring projects dig deep into your pockets, there’s the disruptive nature of the project to consider. But despite what seems like two distinct disadvantages, here are the many benefits that outweigh them and support your decision for home rewiring.

New wiring, new electrical power experience
A dependable electrical system
No more flickering lights, burning smells, or shortage of power
More room to add new appliances and remodel
Save on energy bills
Improved electrical safety
Reduce the chance of a power cut
Ensure electrical wiring lifespan
Prevent damage to your home appliances
Increase home resale value

While a home rewire is an option for many reasons, not just any homeowner should rewire their home. There are conditions under which a home rewire is needed and they include:

If your home is old, and the wiring is outdated
You have hazardous aluminum wiring
You are renovating
Your electrical system is unsafe with several faults, flickering lights, and so on.
Your electrical wiring has insufficient capacity

When you are experiencing any issues with your electrical system, it’s advisable to call on a professional Los Angeles electrician to inspect your wiring and point out the issue. The electrician will advise on if a home rewire is needed.

How to rewire room by room

Make a list – Make a list of the appliances you have now and those you would like to add in a few years. It’s best to think as far as 25 years. This is because most rewiring projects are done every 2 decades. You can consider installations like:

Lighting and ceiling fans
HVAC
Kitchen appliances
Water heater
Devices such as wheelchair lifts and stairlifts
Home office electronics
Hot tub, spa, sauna or swimming pool
Entertainment systems

Get an electrical building permit – The person who will perform the rewire project has to pull a permit before the work can start. If a rewiring project is carried out without the necessary permit, you might have to take it all down later.
Get to work rewiring room by room – Shut off the electrical power to the home, disconnect circuits, and disconnect wires from electrical boxes. Draw a plan of your new circuitry. Cut holes in the drywall to install new outlets and switches. Run the new wires through the backs of the electrical boxes and staple lateral runs of wire with wire staples. Run the wiring for the new devices and connect each new circuit.

Attempting a rewiring project yourself is no joke, and it gets worse if you have no electrical experience or knowledge. It is always better to leave such demanding electrical services to professional electricians. Hiring a professional saves money in the long run, guarantees electrical safety, and is stress-free for the homeowner.

Be sure to test all your electrical components after the project and ascertain they are working fine. If you opted for DIY, ensure a professional electrician inspects the wiring room by room afterwards.

Can I use an extension cord to run power outside?

Posted on March 24, 2020 | by K Hopkins

extension cord legal Getting power within the home is easy. You are already set up with outlets, cables, and extension cords. So, all you have to do when you need to put on the TV, use the microwave, or other appliance is plug in and switch on. However, when you need power outside, it’s different. Running power outside depends on a few factors starting from what you need power for, or rather the duration of use.

Power Outside for Short Term Use

Yes, you can use an extension cord to run power outside if you only need power for a short time. This can include quick activities like trimming the bushes or illuminating a party in your backyard. An extension cord built for outdoor use has you covered from hours to up to two days outside. It’s important you note the use of the term outdoor extension because not all extensions are built for the conditions outside your home. An indoor extension should not be used even for only a few hours outside. Purchase an extension cord identified as an outdoor extension cord.

Also, note that even outdoor extension cords built for use outside should not exceed more than a day or two in use. This is to prevent vital parts of the cord from breaking down and leading to electrical fire or shocks.

Other things to consider when using extension cords for outdoor use

After ensuring you use an outdoor extension cord, verify the wattage before purchasing it. The cord should be able to accommodate the wattage needs it will be connected to.
Next is the length of the cord. Electricians would often advise on using long extension cords outside the home. However, there’s some discretion to be applied to how long or how short the cord should be. A short cord might not meet your needs and a lengthy cord can easily become a cause for accidents, tripping, and falling. Choose the right length according to your needs and be sure to clip a longer cord or its excess to the ground or tuck it neatly away from sight and foot traffic.
Also, ensure that the cord is plugged to a GFCI outlet outdoors. A GFCI outlet grounds the current and protects against shock if the cord is exposed to water.

Power Outside for Long Term Use

When you need power outdoors for more a day or two, an extension cord won’t cut it. Perhaps you need to light up the lawn regularly or something else. In this case, you would need a professional electrician to install outdoor electrical cables and GFCI outlets. This is not a DIY task. The electrician will dig trenches 18-30 inches deep depending on the specifications of electrical code. The cable will be encased in solvent-welded PVC conduit and connected from both ends to GFCI outlets. It requires expertise, tools, and experience. Afterwards, you will have a safe and dependable outdoor source of power.

Is cloth-covered wiring a safety concern?

Posted on March 12, 2020 | by K Hopkins

cloth covered wiring safety If you are planning to purchase an old home or you are already living in one, then chances are you may have seen cloth-covered wiring in the home.

Electricity was discovered in the 1800s, and it was not until the 1900s it became common in homes and buildings. As you might imagine, technology hadn’t gotten so far either, so cloth-covered wiring seemed like a good solution at the time. It wasn’t until the 1960s that plastic covered cables were introduced.

So, is cloth-covered wiring a safety concern? Short answer, YES.

Cloth-covered wiring served as standard insulation during those early times and kept homes running on electricity for several years. However, in recent times, the drawbacks and dangers of cloth-covered wiring have become more obvious and dangerous. Cloth-covered wiring is also quite outdated and out of standard.

Some risks posed by cloth-covered wiring include its vulnerability to being chewed by rats and insects and getting worn or torn over time. Either of these will cause the wire underneath to be exposed creating a major fire hazard.

Cloth-covered wiring is also associated with what is known as knob and tube wiring. During the time that cloth-covered wiring was popularly used, knob and tube wiring was the standard method for running these wires through homes. The knobs and tubes in question were made of ceramic and used to run the wires through the walls. These installations are prone to breakdown, do not supply enough power, and do not carry the safety features of modern wiring methods like grounding.

In addition, some cloth-covered wiring was further insulated with asbestos paper. When wear and tear or brittleness occurs, the asbestos may breakdown releasing its hazardous particles in the air. Asbestos is a known carcinogen to humans and extremely dangerous. All of these contribute to why cloth-covered wiring is a safety concern.

What you can do

The good news is you don’t have to take your purchase elsewhere or abandon your home for safety reasons. Cloth-covered wiring can easily be replaced by professional electricians. A whole-house rewiring will eliminate the presence and dangers of cloth covered wiring.

What is required?

A professional electrician is a first and most important factor in a whole-house rewiring project. The electrician will inform you of what is needed including the cost. Whole house rewiring can be a bit demanding financially but it’s well worth it for the electrical safety of your home, family, and appliances. You will get an all-round improved electrical system with the current electrical standards, grounding, new electrical panel, three-prong outlets, and GFCI outlet protection against shocks and much more.

How do you pull a new wire through a wall?

Posted on March 6, 2020 | by K Hopkins

Wiring a home under construction or during a remodeling project is easy, mostly because the walls are accessible. The real difficulty comes when you are trying to pull a new wire through a wall – an already existing wall.

Ideally, this is something you can do with some electrical knowledge and a step-by-step procedure. Here’s how electrical technicians get it done.

Tools you need

Stud finder
Drywall saw
Electricians fish tape
Wire stripper
Electrician’s tape
Auger bit or drill
Cable

Wiring Steps

Before diving into any electrical work, it is crucial to shut off power to that area completely. Go to your electrical panel and turn off the power. To ensure you have proper lighting without electrical power, carry out this project during the day.
Ensure there is a clear path to thread the wire through by using the stud finder to check for studs, pipes, or obstacles in the wall. Plan your route with this.
Next check the attic, basement, or crawlspace to confirm you have a clear path for threading the wire.
On the main floor, identify where the wire will exit. Draw the outline of a box and ensure it is in line with others you have before. For example, if you are fishing the new wire through an outlet, check that your outline is on the same level as others. This is usually 12-18 inches above the floor. Use a drywall saw to cut out the hole following the outline. After cutting the hole, use a drill or auger bit to drill through the wall plate. Repeat similar procedure with the drill in the attic or basement where you would like the wire to enter through.
Tape the fish tape tightly to the cable and make sure you have excesses or enough wire and fish tape to grip. Slide the wire through the opening. It is easier to fish a new wire through a wall if you have someone on the other side to help you pull on the wire if anything happens. Fish the wire gently by pulling at short intervals on one end while your helper feeds more wire from the other end.

If you run into any roadblocks, you will have to repeat the earlier process of drilling another hole in the wall to fish the cable’s free end.

To make it easier to pull the wire you can employ a method that professional electrician’s use. Coat the cable with a lube product. This lubrication makes the cable slippery and easier to pull while protecting the sheathing from tearing.

If the procedure is just too difficult or time-consuming for you, the best option is always to call a professional electrician.

Is Cloth Covered Wire a Fire Hazard?

Posted on February 20, 2020 | by K Hopkins

house rewire signs Electricity has been with us for decades. The industry continues to make new discoveries and update on former methods and as a homeowner, it might seem tasking to keep up. The good news is with every innovation comes safer, more efficient, and convenient electrical systems. You get to enjoy all the benefits still.

Cloth wiring

It might seem strange to some, but if you have an old home, it’s possible you have cloth wiring. Cloth wiring is exactly what it sounds like. They are wires sheathed or insulated in cloth. They are easy to spot because of the clothed exterior. This type of wiring can be found in homes wired anytime from the first half of the 20^th century.

Yes, at the time they seemed like a good idea and served their purpose. But as the industry progressed it quickly became clear that cloth wiring posed several risks to homes.

How did cloth end up on wires?

Electrical wiring of these modern times is often covered with PVC insulators. This protects from shock, short circuits, and arcing. These insulated cables are then run as a group into multiple-conductor cables or individually but still within a protective conduit. Plastic which is an ideal insulator for copper was yet to be invented at the time electricity was. Hence, all of these described above was unavailable. Cloth became a grand option.

In cloth-covered wiring, the conductors are first insulated with an early plastic better known as vulcanized rubber. After this, they were wrapped in braided cloth. They worked until the drawbacks set in.

Is cloth wiring a fire hazard?

Short answer – Yes. Long answer – It’s more than that.

Cloth wiring presents all sorts of dangers, especially in these modern times. For starters, the outer cloth sheath is prone to deterioration and so is the inner vulcanized rubber. Cloth wiring is also not only out of date but an easy target to be chewed on by rodents and rats. All of these leave the wires within exposed. This exposure can lead to arcing, short circuits, shocks, and ultimately fires. Electrical fires caused up to 440 deaths and 1,250 injuries every year for the period of 2012 – 2016. Even now, it leads to over $1.3 billion worth of property loss each year.

Having cloth-covered wiring might indicate your electrical system is not properly grounded. Older homes were improperly grounded at that time, and this poses even further risk to your home now.

What to do about cloth covered wiring?

If you notice you still have cloth covered wiring, it is likely time to consider an upgrade/rewiring project. It is a demanding project both financially and practically but in every way worth it for your safety and the safety of your property. An upgrade will provide you with replacements of any other aging material, a better electrical panel, GFCI outlet protection, grounding, modern three-prong outlets, and more.

Electrical Cord Safety

Posted on February 16, 2020 | by K Hopkins

Electrical cords are the cause of a lot of accidents and injuries around the home. The Electrical Safety Foundation International (ESFI) estimates that about 4000 injuries and about 3300 homes have fire accidents as a result of misusing extension cords. There have been around 50 deaths and 270 people injured because of these incidents.

The most common cause of injuries is from tripping over these wires. This has resulted in fractures, contusions sprains, bruises, and lacerations. There are situations where the victims had to be hospitalized.

You do not want to be part of these statistics and the Electric Connection offers some tips on how to use extension cords properly.

Use extension cords temporarily and not as permanent fixtures. If the cords are used and taken away, the chances of you or others tripping over them are reduced drastically.
Do not overload an extension cord. The ratings of an extension cord indicate how much load it can carry. Knowing this will guide you on what kind of devices and how many devices you can connect to the cord.
Use the cord for its indicated use alone. An outdoor extension cord should only be used for outdoor purposes and vice versa. Outdoor cords are usually thicker and built to withstand weather conditions. Using the appropriate cord will help protect you from harm and reduce potential dangers.
Check each cord before you plug it in. You should inspect the cord for damages such as frayed wires or bent plugs. You should also check for anything that could lead to electrical shocks. If a plug is hot, do not plug it in.
Run extension cords in open spaces. When you are passing a cord, avoid running it through walls or ceilings. This will help reduce the chances of the cords overheating and posing a fire hazard.
Avoid placing the cords in places where the insulation might be damaged. There are situations where people run their cords between doors or windows or place them under home furniture. This is wrong as this might cause damage to the wiring and damage the insulation, leading to electrical hazards.
Use cords in areas with the least amount of people. Passing a cord through a door or a walkway poses the threat of someone tripping over it as these are routes people pass through a lot. You should run your cords along paths with the least human traffic.
High power devices are not to be connected to extension cords. Microwaves, heaters and the likes draw a lot of power and should be connected to outlets directly and not through cords. This will ensure your cords do not draw more than their rated power.

You should only buy extension cords suitably rated for the load you want to power. If you are connecting multiple devices to an extension cord, you should ensure that their total load doesn’t surpass the cord’s rating.

The Electric Connection can and will provide professional assistance for electrical situations around the home. You can contact us for additional details and questions.
