Two 30a Controllers on a 60a Spa Panel Help

[bzevotek]

So I am building a 30a PID controller but wanted to future proof my set up so I went and got a 60A Spa Panel. Do I need a small subpanel that uses the 60a wire (after the GFCI) to "mains" to set up two separate 30A circuits if the plan is to start with one controller and move to a second eventually? Would the gfci still protect the entire sub? The plan is to have the ability to run simultaneous 5500w elements but I don't plan on adding the second controller right away. Ultimately I'm planning and eHERMS but starting with a recirculated BIAB set up.

Just make sure your control panel has the correct 30a breaker or fuse in it or on the line leading to it and youll be fine... I use a 50a spa panel myself but only have a 30a controller since I have no need to heat my BK and HLT at the same time and 30a is enough to run my 4500w BK and 2000w rims simultaneously.(only do 5 and 10g brews on it)

I use a 30a break in my main panel that feeds to my 50a spa gfci..
