WebFeb 11, 2015 · I guess a cable/panel's current rating is what it is regardless of what voltage it is applied at. It just seems like there is something i am missing. The time - current curve (TCC) is based on time and current. Current is current. 100A at 240V is exactly the same amount of AMPS as 100A at 480V. WebOct 15, 2007 · One method of ensuring selective coordination is to examine each overcurrent device’s time-current curve (TCC) and verify for any value of current, that the protective device closest to the fault clears faster than any upstream device. To interpret the curves, locate a value of current on the bottom axis and follow that line vertically until ...
