I have a question regarding sizing of conductor ampacity and overcurrent protection for an electric furnace that is part of a heat pump system.
1) I am under the impression that this fixed heating equipment is considered a continuous load, and therefore the overcurrent protection device can be rated at 100%-125% of the conductor ampacity, correct?
Here is the nameplate of the unit in question:
The system is fed from the main panel by a 60 amp breaker with 6 AWG NM-B. There are two 60 amp breakers installed at the unit (sealed area, not allowed to open as a home inspector to look into it).
This doesn't seem right... It would seem that since it has a single circuit supply, it has undersized conductors and OCPD? No?
I feel like I'm missing something obvious.
