Split Receptacles 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.
Basic electricity including electrical definitions, ohm's law, and electrical circuit information including direct and alternating current.
Wire Connectors are used to connect two or more wires together. There are many types of wire connectors, the most common are twist-on.
Electrical Troubleshooting There are certain things that you can do in a home or office to troubleshoot and fix certain electrical problems.
Troubleshoot 4-way Switches Usually when a 3-way or 4-way switch fails, lights can be toggled on and off on all but one switch.
Alternate 3-Way Switch Wiring Diagrams Conventional 3-way wiring is not very complex. However there is an alternate wiring configuration that could cause confusion.
Ballast Wiring A fluorescent tube circuit includes a ballast, wires, lampholders, and the tubes.
Fluorescent Ballasts Fluorescent lamps use a ballast which transforms line voltage to a type of power to start up and operate the lamp(s).
Replace Ballasts How to replace a fluorescent ballast, including 2, 3, and 4 lamp series and parallel ballasts. Includes a how to replace a ballast video.
Fluorescent Lampholder Wiring Fluorescent lampholders hold fluorescent tubes in place on a light fixture. Wires from the ballast plug into push-in connectors in the lampholders that connect to the pins of the lamp.
4-way Switches 4-way switch configurations are used to control lights with three or more switches.
Ceiling Fan Switch Wiring 3-wire cable travels from the switch box and connects to the fan, lights, neutral, and ground wires.
Troubleshoot 3-way Switches Usually when a 3-way switch fails, lights can be toggled on and off at one switch, but not the other.
Multiple Switch Wiring Multiple light switch wiring using NM cable. Includes wiring diagrams.
3-way Switch Wiring How to wire 3-way switches using NM (Romex) cable with wiring diagrams included.
3-way Switches 3-way switches are used to control lights with two switches.
Dimmer Switches are used to control lighting level and can save energy.
Switches are used to control power to a load. They can be found on anything that runs on electricity.
Light Switch Wiring With conventional light switch wiring using NM cable, the NM supplies line voltage from the electrical panel to a light switch outlet box.
Electrical Outlets A receptacle (electrical outlet) is a device that supplies power to an electrical load through a cord and plug.
Outlet Wiring Diagrams showing how outlets are wired using NM cable (Romex). Diagrams also include a dryer outlet and typical ground connections.
