It does cost more money but you could take out your 4 peanut breakers and install one 2 pole gfi breaker in the 30-50 amp range and run a 4 wire cord over to your control panel. By doing this you could use the two legs as separate 120 volt circuits and not have to change your existing keggle elements.
So if I do this, I just need one 30 amp 240v gfci breaker, right? This will in effect provide two 30 amp lines, correct?
I can then run these to my two contactors and use fuses to protect the #12 gauge wires.
But will the gfci trip if just one of the elements is losing current? Or will both cut off in this circumstance?
Thanks for the ideas. I think this is the way I'm going to go if I can put a gfci in the panel that will really protect everything down stream.
