Ambient Compensation Chart
To use this chart: Read up from the ambient
temperature to the curve, and across to find a correction
factor. Multiply the breaker rating by the correction factor
to determine the compensated rating. Calculate the
overloads in terms of the compensated rating to use the
published trip curve.
