Re: spaceheaters

Try 220.15( Stand. Cal.), 220.30(C5)
( Optional) or 220.31(B)(Opt. Add.), 424.22 OCP
Maybe this will help!

Re: spaceheaters

19.2KVA + 1KVA + 1KVA = 21.2 KVA.

(21.2) x (1000 VA) / (240 Volts) = 88.3 amps.

With the information you provided, there is no applicable demand factor that would allow you to reduce this value.
