An electrical circuit’s job is to deliver a safe and reliable supply of electricity to your home. It does this by connecting one or more of your appliances with the power supply, which is usually generated by an electric utility. The electrical wiring for a typical house is usually installed by the local electrician and is marked by various color codes on the wires.
Installing the electrical wiring and outlets in your home is a project you can manage on your own. The equipment and tools you need for this project are shown here.
The very first step is to locate the electrical circuit at the beginning of the project.
Your electrical system includes two main parts:
the circuit breaker panel and the outlet boxes. Outlet boxes are connected to the circuit breaker panel by a four-conductor wire called a “hot” wire.
This is usually identified by a black, white, red, or green colored wire. The breaker box will contain different colored wire color codes, and the wire colors will correspond to the wire codes on the circuit breaker.
After you locate the circuit breaker panel, you will need to locate the circuit breakers and switch the circuit breakers to the “off” position to allow you to work on the circuit. To locate the circuit breaker, you will use a multi-meter, an ammeter, and a volt meter.
The multimeter is used to measure the voltage of the circuit. This is useful to see if the circuit is energized, which is indicated by a 120-volt power source. A 120-volt circuit is typical, but a 240-volt circuit is also common.
This is not as simple as it sounds. A 120-volt circuit is 120 volts, and a 240-volt circuit is 240 volts. The multi-meter will show you that the circuit is 120 volts, but it does not show that the circuit is 240 volts.
A volt meter is used to measure the current in the circuit. It is a one-legged instrument that usually includes electricians in Carmel, IN a center scale that measures volts, a right scale that measures amps, and two hands that measure the voltage of the circuit.
The ammeter is used to measure the current in the circuit. It is a two-legged instrument that usually includes a center scale that measures amps, a right scale that measures volts, and two hands that measure the amperage of the circuit.
