question about
My electrician replaced the circuit breaker panels in my house last October. The 100-amp breaker for the sub-panel that handles the two resistor heating elements in the attic (which we don't usually use, but we had to recently, because our boiler went out) kept breaking, because the two units are each rated at 60 amps, so that when both heaters went on, its load was exceeded. When I asked the electrician to remedy this, he said that I would have to pay for the additional work, since there had been a 100-amp breaker there, before, and he had simply followed the configuration of the previous panel when he installed the new one (the reason it had never broken before is that the previous panel was FPE). Is copying the configuration of the old panel customary practice, or is it the case that he should have double-checked what was on the business end of that circuit? (My HVAC contractor, for one, when he came to fix the boiler, said that the electrician shouldn't have assumed anything, especially since this is an older home.) I'd very much appreciate any opinions you can offer.
