After reading through LJs many excellent comments, suggestions & reviews regarding 220V current, required gauges of wire & connecting of power tools of all shapes, makes & sizes – I have found that my situation leaves a few questions unanswered. I know you L-jocks will pull through for me with some good feedback.
Recently I’ve purchased a dedicated 220V DC with 2HP TEFC motor running 12A full load with a recommended 20A circuit and wired with what appears to be 14gauge?? from the motor to a dinky 220 plug.
My workshop is a small sunroom facing south with alot of sliding glass doors – great for lighting & sunshine. However being originally built as a sunroom it comes equipped with only very limited 110V outlets. Adjacent to the shop is our laundry room with the electric dryer and its dedicated 220V. My first thought is to purchase a dryer type plug to match the 220V wall outlet – which is 10 gauge & on a 30A circuit – and plug the other end with a more conventional 220 F-plug and make like an extension cord. Then rewire the electric motor with 12 gauge and plug the end with a M-conventional 220. The dryer & the DC will not be running at the same time – this goes without saying! Switching the dryers wall circuit to a 20A is not an option either – this requires no further explanation, as the wife has at least some say in this.
So my first question is – Is it safe practice to plug a 12 gauge cord rated for 20A into a 10 gauge cord rated at 30A? Oh, and at the same time, not burn the motor out or fry my laundry room.
My second thought to approach this scenario is with the multiple 110V outlets in our laundry room – take one of the duplex outlets and convert it to a 20A 220V dedicated outlet for the DC.
I have good handyman status, but have limited electrical wiring experience. I am an Audio-Video Tech by trade so am very familiar with cables, wiring, connectors etc.
Any thoughts & suggestions are much appreciated. Steve
