Thanks for all of the responses. I will go with 230kVA in my calcs.
I am aware of the in-rush current loading on the resistance heaters. We will most likely ramp them up genetly to minimize in-rush load, but will size the conductors to handle the max load as well.
Thanks again to all!

I need to calculate electrical load for some (non-standard) electrical heating equipment, that will operate at 480V, single phase. I'm not an EE and I'm not sure of the correct method to calculate loads for a 480V, single phase application.
Here's the short summary: We are going to have 3...
