The panel had a 30 amp GFI breaker in it. I switched it to 40 amp GFI breaker yesterday which is called for on the 6000 watt heater. The electrician tested the load on wires to peak at 35 amps. Both tripped when heater reached temp setting. With a regular 30 amp 2 phase breaker the system works fine!!

GFIs are known to sometimes have nuisance tripping due to their sensitivity. As to whether you can leave the nonGFI breaker in there or not, I can't answer that because I am not an electrician. Hopefully someone can provide a better answer. The breaker does need to stay 30 amps, assuming the wire is 10 awg. Hope this helps.

Mike,
You first need to review what the manufacturer's requirements for what the "listed" circuit breaker size and type are... It's not just an electrical code requirement (I assume you are in the USA) but it's a liability issue.

All saunas and hot tubs I've seen require GFI circuit breakers for power. If you replace this with a normal circuit breaker and someone gets hurt, it's your fault! If you have installed the sauna in accordance with the manufacturers installation instructions and have a problem, you need to contact the manufacturer for their solution or recommendation. The GFI breaker is a safety feature, not an option.
