To use this chart: Read up from the ambient tem-  
perature to the curve, and across to find a correction  
factor. Multiply the breaker rating by the correc-  
tion factor to determine the compensated rating.  
Calculate the overloads in terms of the compensated  
rating to use the published trip curve.
