Hi,, Can someone help me by answering this question. What size wire and what size Circuit breaker is needed to hook up a 5kw heat strip in a Nordyne/Miller heat pump.Q5rd. ??
My 4 1/2 year old compressor went bad and when the HVAC contractor came to diagnose the problem,, he told me that the wiring for the separate 10kw and 5kw heat strips were wired incorrectly even though I never had problem with the heat strips before. He changed the wiring and CB on the 5kw from 10/2--30amp to 6/2 -- 60amp. I am currently getting heat by keeping the thermostat on Emergency Heat until the warrantied compressor arrives. But Recently,, I was told by the master electrician who initially hooked up the 5kw, that the current wiring is oversized,, a possible violation of the NEC code and possibly a potential fire hazard. Is this new wiring a fire hazard and should I change it back to 10-2---30amp CB ?
