The basic components of house electrical wiring

Electricity is provided to our houses with a complex electrical wiring system. It is designed very carefully to provide the necessary power for our safe and comfortable living. Here is a short guide about how your house electric system works. Hopefully, it will help you to be more responsible and solve many issues related to it.

Home electrical wiring system consists of utility’s power lines and service entrance.

Service entrance

Service entrance is equipment bringing power to the home. And the power runs through the electric meter which records energy usage.

Electric meters

Electric meters can be analog which mechanically displays the numbers or digital type which shows a display on an LCD screen. Notably, these are the numbers that create your electrical bill. Electric meters are located on an exterior wall or inside the breaker box which is usually located at home.

Breaker box

The breaker box is the main service panel which distributes power to all circuits. Usually, the size of the main breaker dictates the max amount of electricity that you can use at one time. Actually, if there is an overload in the home the breaker will flip off and reduce the risk of fire.

When doing an electric work always remember that power going from the service lines to the electric meter and to the main service panel is always live. Thus, it means that you should shut off the panel before doing any work. You can do it by the main breaker in the service panel.

If you want to know the total amps of your electric service look at the larger breaker switch in the main breaker panel. Indeed, 200 amp services is a common number for the most modern medium homes. And, if your house is large you should have up to 400 amps.

Electrical Boxes

For installing devices (for example switches, fixtures, etc.) and connecting wires you should use electrical boxes. They can be plastic or metal of different sizes and shapes. The shape and the size of the box should match the size and number of wires. The difference between metal and plastic boxes is that the metal boxes grounded to the home’s grounding system, but plastic boxes don’t need it.

The electrical circuit contains:
1. 1 hot wire – carries the electrical current from the service panel to the circuit devices,
2. Neutral wire – carries current back to the service panel.

Ground Fault Circuit Interrupt (GFCI)

Indeed, in electric system safety is very important. Thus, Ground Fault Circuit Interrupt (GFCI) outlet or breaker is used to maintain safety in the house. These devices shut off the electricity anytime there is a risk of someone being shocked. They are usually placed in the areas where there is a lot of water (bathroom, kitchen. etc.).

Now, you know the basic components of your house’s electrical wiring. However, this won’t be enough to do any serious job. Indeed, problems with electricity can be very dangerous. And, for being safe it is better to turn to professional electricians. You can find good advice from professionals in United Electric Wholesale & Trading.
