I recently had a heat pump 25HCB330 and fan coil FB4C30 installed both Carrier with a 20KW accessory element KFCEH3201F20.
My electrician prepared a 100amp breaker for the furnace with heating element. My HVAC installer was suggesting that some would put 125amp breaker for a 20 KW element. But my electrician knew I was getting 20 KW element and did not suggest more than 100 amp. Any thoughts on the 100 amps being sufficient. (note i have a separate 30amp breaker for the heat pump)
Thanks for your help!
