Hello,
I?m doing a service calculation for a modular home, it?s an all electric house,
with a 20 kw forced air furnace. I?m using the optional calculation 220.82.
Does the furnace fall under 220.82 C4 ( 65% of Nameplate Rating ) or do I use 220.82 C6 ( 100% of Nameplate Rating )?
The home owner wants to finish off and add a 2nd kitchen downstairs to this home, so I need to show service calculation that are under the 200 amp rated panel that is installed in this modular, if the furnace is rated at 100% it will be cutting it close.
Also, is there a code article that prevents me from using table 310.15 B6 for sizing the service entrance conductors, with the 20KW furnace load?
Thanks
