New Home Wiring and Electrical Service Size

By Dave Rongey - Summary:

How to Calculate Home Electrical Service Sizes: The size of the home electrical service panel and the size of the electrical utility company transformer is determined by creating a list of all of the projected electrical loads, the proposed equipment that will be connected to the circuits, the efficiency factors of this equipment, and the designations for the total building space.
