Hello, I've setup my CNC router in the basement. The clothes dryer and service panel are in the utility room directly above the router table and it's roughly in between them. The dryer supply runs between the joists directly overhead. I was thinking of tying into this circuit, adding a smaller breaker for the VFD (typical 220v/2.2kw) and a switch so the dryer isn't inadvertently used while the CNC is running. Something like an aux generator transfer switch with integrated breaker, but in reverse. I have the ability to run a dedicated circuit, but I'd really rather not if there's a perfectly good breaker already in the panel (dryer) not being used 90% of the time.

Are there better ways to do this? Or has anyone done such a thing and can offer tips? Thanks!
