All About Wiring Diagrams

This post will help you to understand wiring diagrams , including how important it is to use wiring diagrams, all the proper terminology relating to electrical wiring diagrams, and how to find the correct wiring diagram(s) on my website.

Follow these instructions and we’ll have you wiring a switch, wiring a 3-way switch, a 4-way switch, wiring a receptacle and more. My goal is to help you to complete your home electrical wiring projects with ease!

What is a Wiring Diagram?

An electrical wiring diagram is essentially a schematic representation of an electrical circuit. It can be anything from a crude diagram scrawled out on a piece of cardboard, or a napkin, to a sophisticated electronically produced wiring diagram. In your home electrical projects, it is very important to use wiring diagrams. They can assist you by providing a road map for planning and completing your home electrical wiring projects, saving you both time, money, and frustration.

When do we Need a Wiring Diagram?

The two most common applications for using a wiring diagram in relation to your home electrical projects would be:

1. To help you understand what connections need to be made after running your cables, and how to make those connections.

2. To capture how connections and splices are in an existing installation, so you can replace a defective device, or repair a poor connection or splice. A good example of this would be replacing a 3-way switch. Diagram how the connections are before you disconnect the old 3-way switch, especially noting what wire is connected to the common terminal, then wiring the new 3-way switch will be simple!

What is a Wiring Device?

The Receptacle

The most common wiring device that you may need a wiring diagram for is a receptacle. Wiring a receptacle is very easy if you have a wiring diagram for making the proper connections. One common mistake people make is referring to a receptacle as a plug. They will ask me how to wire a plug or a plug-in, when they should be asking how to wire a receptacle. A plug is what goes into a receptacle. Remember it this way: At the end of my lamp cord is a plug, and I will insert that plug into the receptacle.

Here is a basic diagram for wiring a receptacle.

The Single-Pole Switch

Another useful wiring diagram is how to wire switch. Wiring a switch is really quite simple and easy to understand. A single-pole switch is very common in the home, and is used for controlling a light or lights, or a switched receptacle from one location. A switch simply interrupts the flow of electricity to complete or break the circuit to a light or a lamp.

The 3-way Switch

The three way switch is another common device within the home. It is used to control a light or lights, or a receptacle for a lamp, from two locations, like at either end of a hallway, the top and bottom of a stairwe...
