Wiring residential Thermolec 12KW electric boiler (B-12U FFB) with nameplate 47.92 amps and a specified 1x60amp breaker. Spec calls for “always use 75C(167F) min”.
Are we correct that 6/2 NM-B is limited to 55amps and 60C sheath. Therefore we cannot use NM-B and must use at least 6AWG cu in conduit?
As a side note, a conduit run is very time consuming given the 12” OC joists.
