I will be preparing the electrical for a new hot tub installation. I have a sub-panel inside the house in the basement literally 2-3 feet from the panel. That panel also contains a 40AMP GFCI wired to a digital timer inside the house to a double-pole switch and outlet which turns the pool motor on and off that was installed by an electrician.
I would like to do the same thing with the hot tub so that I can keep the 50AMP GFCI breaker in the sub-panel out of the elements, then connect that to a turn-off switch outside which would then feed the hot tub. What I am confused on is the AMP rating for the switch. Do I need to purchase a 50AMP double pole switch (ex: https://bit.ly/2lwNOey)? The pool motor is using 12-3AWG out of the timer to a 30AMP double pole switch making the connection to the switch easy. If I run 6AWG from the 50AMP GFCI breaker to a switch, I am not sure how that could be connected. Can it be less gauge wire? Do I use crimped on connectors?
Any help/input would be appreciated.
