I've searched for this, I hope it hasn't been covered before! What would be wrong with using the breaker bracket/busbar assembly from a 125a sub panel inside my control box? I think it would make it very simple. Just feed the box with either a 50 or 60 amp cord to the busbar and use a 2 pole breaker for each 5500 watt element. Add a 15a breaker for the pump(s) and a fuse for the PID/SSR. It should be safe, and allow for future changes in design. I'll use a GFCI at the main panel.
