I'm trying to fill out a load sheet for the POCO. The service voltage is 240V/120V single ph. The customer will have a 3ph 10HP air compressor, it lists 28A for 230V 3ph. They will use a phase converter for the compressor.
The RPC specs:
30 HP
240V
22 KW

I don't know if you use Table 430.250 for the compressor, or if the load should be listed as all single ph.
I think I could just show a total load in KW for the compressor, but not sure how to figure with a mixture of 3ph and single ph.

Help!
 
I would use the total KW for the compressor (about 11.2kw?) at 3 phase +something?? for the RPC. Maybe you canf ind out from the RPC mfg what to add. Using the full 22kw would be a big # to use IMHO
