I've a Square D subpanel w/out gfi. I read about getting a spa panel from home depot, but all I see on the website is a GE or Eaton make. Anyone know if those gfi breakers will fit a square D panel?
If not, I guess I'd have to install the spa panel in the shed and feed it from my shed subpanel to get a working gfi for the 120/240 toolbox control panel I wish to build one day. My shed panel has a 40 amp master breaker, does it matter if the spa panel is a 50 amp gfi breaker?
My goal is to make a toolbox panel with a PID that can control both a 120 volt 1650 watt heat stick for heating mash water, then switch over to a 3500 watt 220 volt element in a boil pot.
Thanks for any insight, this is going to be a project done in stages but one I'm looking forward to.
ps..why is a spa panel with 50 amp gfi breaker cheaper than buying a 30 amp gfi breaker??
