Planning Home Workshop Electrical Wiring

Question: I will be running new 120v and 240v wiring for my home workshop.

A friend told me that I must use a home-run for each 240v outlet. Is that true? If so, is there an alternative?

The books that I have don’t seem to address this issue.

Dave, thank you so much!

This electrical question came from: Chuck, a Homeowner from Raymore, Missouri

Additional Comments: I tried to find the solution by using different search criteria, but I was not successful. I’m sure I just didn’t use the right criteria, but I tried.

Thanks for your electrical question Chuck
Workshop Electrical Circuits for 240 Volt Equipment
Chuck, home-run wiring in this case refers to a dedicated circuit, and dedicated circuits are required for specific 240 volt equipment such as welders, air compressors, pretty much any 240 volt equipment here in the USA (this is not the case in the UK and other areas where all of the home circuits are 240 volt.
120 Volt Workshop Circuits
Workshop circuits that supply 120 Volt power to lower amperage devices like a drill press, bench grinder, sander, hand saws etc. generally supply power to several receptacle outlets and do not require a dedicated circuit for each device.
Planning Home Workshop Electrical Circuits
It is best to make a list of all the equipment and devices that will be used in your home workshop, including the lighting and any heating, air conditioning or exhaust fans. Once this information is known then the electrical panel can be sized for the size and number of electrical circuits for your workshop.
