I’ve looked through a lot of information. My machine is ordered and expected the week of May 23, 2021. I have a question about circuit setup. I have a 20 Amp circuit I’m using for a hot tub only. I am thinking of wiring into that for my CNC since I will only use one at a time. I.E. the hot tub will…

Are you using the same outlet for both or doubling up wiring to another branch? I’m more than confident electrical code does not allow for using a single protection device (circuit breaker) for parallel circuits regardless of duty cycle. I know many of us are probably guilty of doing that with ou…

Having the circuits in parallel isn’t an issue; most outlets in a room in a house are wired in parallel. The exception are the ones run on a dedicated circuit (a fridge, for example). So long as you use the proper gauge cable for a 20amp circuit, wire it, and mount it properly it would be safe. No…

Phil and Chuck: Thanks for your input. I will take both into consideration. Local code requires the hot tub motor on a separate circuit. Since I almost never use it and would never use it while using my CNC, I believe it will be fine. If need be I will disconnect my hot tub.

To be a bit clearer, if you are adding a second branch to your service center’s circuit breaker, i.e. hot tub, it is not advisable to ‘double tap’ at the breaker. Double tap means putting two wires on the breaker’s terminal An acceptable approach is to pigtail both branches so that only one wire i…

I will not be going into the circuit panel other than to turn the breaker off. I will be using a junction box in the attic. Will cut the main wire and then run two separate wires to each utility. Outlets will be GFI.

Good plan and should work great.

I asked about power requirements back in November. Power requirements for controller . I think you will find this helpful.
