I've searched the forum and can't see to find a consistent answer for this. What size wire should I use to go from a 50A breaker in my main panel to a 50A spa panel with GFCI to my control panel? I feel like I've seen both 6 and 8 gauge copper THHN recommended. Also, is conduit needed or can the wire just be run through the wall?
I know there are a lot of other things that factor into this so here are some details...
Spa panel will be within a few feet of my main panel in my garage, which is drywalled.
Probably go with a 12-15' power cable to run from spa panel to control panel.
Including option to run 2 elements at the same time so will be pulling 45+ amps occasionally.
I'm going to have someone install the breaker and spa panel but wanted to be able to tell them exactly what I need and why. It's a friend of a friend of a friend type thing so I'd rather be able to have everything ready for them to just install it.
