Hey guys,
I'm correcting the improper installation of an Electric Range / Double Oven for a friend and had a question about the Demand Factors.
The range nameplate rating is 7800W 120/240V or 32.5A.... and the installation manual EXPLICITLY calls for a 40A circuit.
However w/ the permissible demand factor of 80% via NEC 220.55 (Note #3), I'm looking at 26A or a 30A circuit.
My question is, does the installation manual and manufacturer's specifications supersede the NEC and its' permissible demand factors?
Thanks in advance,
Jerramundi
