I'm with Amanda, ask them what they can do for you since they didn't do the building the way you ordered it.
DH said to look on your kiln and it should tell you how many amps it draws, then add more for lighting & anything else you might be plugging in (heater, ac?) and add a little for something you haven't thought of or might be adding. He said make a list of everything & show it to the electrician before he starts work. (DH played an electrician in the Navy and then after her retired from his main job for a while)
