So normally if we have equipment such as a natural gas rooftop unit, or other packaged equipment, I take the MCA of the nameplate, turn it into VA based on the voltage/phase and divide that by how many poles are feeding it. I put that value into each leg of the panelboard schedule. I take a 100% demand factor to size feeders, service, etc. The maximum overcurrent protection device is selected based on the value given on the nameplate.
Is this the correct way to do this?
