shop-wiring Summary: Fully Explained Photos and Wiring Diagrams for Workshop Electrical Wiring with Code Requirements for most new or remodel projects*.

How to Install Workshop Electrical Wiring


Considerations to help determine the Panel Size:

Important Factor: Find out if the Main Service or the Panel that will supply the circuit to the workshop has adequate Load Capacity and space for the circuit breaker.

How big will the workshop be? (Square Feet)
This will be used to size any heating or air conditioning units as well as help you lay out the electrical wiring for workshops with outlets for work benches and stand alone equipment such as drill presses, table saws, welders etc.

Installing Workshop Receptacles

How Many Workshop Receptacles on a GFCI Circuit
Question from Bruce: How many receptacles can I put down stream after a GFCI? I am running a 15 amp circuit in my new workshop with 12-2 wire. This electrical question came from: Bruce, a Handyman from La Mesa, California.

Bruce, for a workshop application it will really depend on what the receptacles will be used for or what will be plugged into the receptacles. The other consideration is how many of these tools or devices will be operated at the same time. If these receptacles are for general purpose and conveniently located and the circuit load will be low then you can place as many as you wish, 10 or may be 12. The point is that you will be limited by the amperage of the circuit, not how many receptacles you actually have. I guess the easiest way to explain this is that just because you have 10 receptacles does not mean that there is a load on the circuit, that only happens once tools or equipment is plugged in and is being used. By the way, if 12-2 wire is being installed then the circuit breaker may be sized at 20 amps, not 15 amps.

Installing Workshop Wiring

Should I Install Electrical Conduit or Cable Wiring in my Workshop
Question from Clyde: I am about to start wiring my steel frame shop building for my 240 V air compressor, welders, and auto lift, plus assorted lights and outlets for power tools. Do I need to run all of the wiring through conduit or can I use Romex?

Clyde, If the finished walls will be open so that the wiring will be exposed then the electrical wiring will need to be installed in conduit to provide protection. However, if the walls will be finished off with a covering such as sheet rock that will provide protection for the wiring then Romex type cable may be installed as long as it is permissible in your area. Ask your local building department when you obtain your permit and they will inform you.
