For an office building, a 208Y/120V power panel has the following loads: Receptacles with a total load of 30.00 kVA at pf = 0.90 Heaters with a total load 12.00 kVA at pf = 1.00 a. Determine the proper frame size and trip rating for the power circuit breaker protecting the panel. Assume an available short-circuit current of 35,000 A at the panel. b. Size the equipment grounding conductor (Cu) for the panelboard.
