First I appologize if this is a stupid quetion...What is the best way to determine how much spare capacity is on an existing panel. If you just take a clamp on reading of each phase would you add up the reading on each leg and then divide by the voltage (e.g. A= 25.0 B= 27.0 C = 24.0 = 76.0/360 x 1000 = 211.1A Is this correct?
I know taking a clamp on reading isn't the best way to determine the load because of the peaks but if you want a general idea of how much power the panel is drawing (or how much spare capacity is on the existing panel) would this be a way to determine it? Any help would be appreciated. Thanks.
