are used to control lighting level and can save energy.
3-way switches are used to control lights with two switches.
A receptacle (electrical outlet) is a device that supplies power to an electrical load through a cord and plug.
A duplex receptacle has removable metal tabs that electrically connect line and neutral together on each receptacle. A split receptacle is a duplex with one or both tabs removed to isolate each receptacle from the other.
4-way switch configurations are used to control lights with three or more switches.
3-wire cable travels from the switch box and connects to the fan, lights, neutral, and ground wires.
are used to connect two or more wires together. There are many types of wire connectors, the most common are twist-on.
There are certain things that you can do in a home or office to troubleshoot and fix certain electrical problems.
includes electrical definitions, ohm's law, and electrical circuit information including direct and alternating current.
Fluorescent lamps use a ballast which transforms line voltage to a type of power to start up and operate the lamp(s).
How to replace a fluorescent ballast, including 2, 3, and 4 lamp series and parallel ballasts. Includes a how to replace a ballast video.
A fluorescent tube should always be replaced with the same diameter bulb. The lampholders are made of plastic, so be careful not to break them when replacing these bulbs.
A plug should always fit tightly into a receptacle. If a plug is loose or falls out of a receptacle, the receptacle needs to be replaced.
110, 115, 120, 125, 130, 220, 230, 240, 250 volts, what are all these different voltages?
A GFCI is a receptacle or circuit breaker that is used to increase safety in areas that are prone to the risk of electric shock.
There are is lot to consider when choosing LED replacement tubes for fluorescent fixtures. Here is what you need to know before choosing the right LED tubes.
For dual-ended direct-wired LEDs, line is connected to the lampholders at one end of the fixture, neutral at the other end.
Circuit breakers protect a circuit from overloads and short circuits. When the current exceeds the rating of the breaker, it will trip. Circuit breaker ratings for household use are typically 15, 20, and 30 amps.
Switches are used to turn lights or electrical devices on and off. Usually when a switch fails, a light or electrical device will not turn on. After determining that a light bulb is not burned out and a circuit breaker or GFCI is not tripped, the switch may have failed.
are used to control power to a load. They can be found on anything that runs on electricity.
With conventional light switch wiring using NM cable, the NM supplies line voltage from the electrical panel to a light switch outlet box.
