To use this chart:Read up from the ambienttemperature to the curve, and across to find acorrection factor. Multiply the breaker rating by thecorrection factor to determine the compensatedrating. Calculate the overloads in terms of thecompensated rating to use the published trip curve.114reference purposes only.
