Residential Wiring Diagrams

By Yudha Urawa

Residential wiring diagrams are diagrams for completing Electrical wiring projects in a home. An electrical wiring diagram can be as simple as a diagram showing how to install a new switch in a hallway, or as complex as the complete electrical blueprint for a new home.

A good wiring diagram shows the placement of the various wires so the project can be completed in a safe manner.

Drawings that contain wiring diagrams also contain symbols which are recognized and adopted as an industry standard within each category or application.

Wire Colors

The wires are colored the same as the actual wires being used. In some instances, such as some switch legs, the function of the wires is indicated by colored electrical tape.

Electrical wiring diagrams that are in color have an advantage over ones that are black and white only. The wires will be colored the same as the actual wires you will be using.

Symbols

Electrical wiring diagrams that are in color have an advantage over ones that are black and white only. The wires will be colored the same as the actual wires you will be using.

For example, a surface ceiling light will be shown by one symbol, a recessed ceiling light will have a different symbol, and a surface fluorescent light will have another symbol.

Switches

Once you understand the different types of switches and follow a good wiring diagram, you should be able to install a new switch in your home.

A Single-Pole Switch provides switching from one location only. "Single-Pole" may sound simple, can be wired different ways and a set of electrical wiring diagrams explains each of them clearly.

There are many ways to wire a 3-Way Switch. A wiring diagram will even take the mystery out of wiring a 3-Way Dimmer Switch. One of the most complicated wiring configurations is a 4-Way Switch. As important as electrical wiring diagrams are to the successful completion of your wiring project, safety and respect for electricity are essential.

As important as electrical wiring diagrams are to the successful completion of wiring projects, safety and respect for electricity are essential. Although wiring diagrams give detailed instructions on completing a wiring project, they can’t replace common sense.
