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.

I would not do that. This would allow raw power to be exposed within your control panel. I suggest that you use DIN rail mounted breakers within your controller. Take a look at these products:

Circuit Breaker-240V-Double Pole 25A
Circuit Breaker-240V-Double Pole 15A
Circuit Breaker-120V-Single Pole
DIN-Rail Component-Circuit-Breaker-Rails

I firmly believe this would be a much safer plan for you to follow.

It shouldn't be any more dangerous than your breaker box at home. Just kill the power before you go in. Once built, I won't be in there messing around.
I agree, your way is safer, but it's easy enough to pull the plug.

You are set on it so why ask the question?

Do it your way, don't ask and just be done with it.

Sorry

I agree din rail is the most ideal, but using common parts isn't bad either. you're going to have 'live' parts inside your control box no matter how you configure it.

Yes, I'm sure that the DIN rail is better, nicer and maybe more cool. But I can't pick that stuff up at Lowe's. I thought the busbar arrangement of the breaker bracket would simplify things since I have no experience with DIN components. I was pretty sure that the terminal strips in the nice setups were exposed with raw power also.
