I think there are actually two options, Judith, "electrical load" or "load list," both of which appear in my references.

It depends on whether or not there is already another entry on your list that would correspond to the other of these two.

The "load list" is the breakdown, by each piece of equipment, of its respective individual load requirement, and "electrical load" by itself would represent the total power requirement from the ships generator(s) for all electrical needs on board.
