We have recently acquired a used Ecco L350 spa. This spa can run on 110v or 220v. I am planning to have a 220v circuit set up for it in the Spring but was wondering if in the meantime I will be alright using a dedicated 20A circuit: 20A breaker, 12/2 wiring on a 30' run from the breaker and a 20A GFCI outlet. The tub is currently configured for 110v use, it has a cord with GFCI plug.
Any input on this temporary setup will be greatly appreciated. Thank you.
