Every article I’ve seen describing the wiring of a shop for both 120 volts and 240V uses separate cables for each voltage, which is a signifi cant waste of time, effort and cable. Here I describe how a single cable can be used to provide both 120V and 240V service to a single two-gang wall box.
For many home woodworkers this wiring method is an easier, less expensive way to add 240V service to an existing 120V shop.
I describe only the connection scheme, and appropriate plugs and receptacles here. You should consult one of the many home wiring books carried at home centers for basic wiring instructions. I strongly suggest those inexperienced with electrical wiring practices (or those who aren’t up-to-date on their local electrical codes) to contact a licensed electrician instead of attempting this on their own. Wiring requires a certain expertise.
