I've got a question on my continuing education test that I can't seem to come up with any of the answers they have to choose from. They're asking for the lighting load on a particular circuit in one of the panels. I go to the circuit directory and it gives me the room numbers. All the rooms have florescent fixtures. I count up the wattage from the lighting fixture schedule, and nothing matches. I then find out in the code that you're not suppose to count the wattage of the lamps to come up with the load, but you're to take the ampere ratings of the lights. I take it that this is the rating on the ballast? Problem is in this test it does not specify the amperage of the ballast. If I just take 20 amp circuit X 120 volts that doesn't come up either. Any suggesions here or is it possible there is not a right answer, and this is just a "trick" question? I'm sure I'm missing something somewhere. Thanks for your input. Steve..
