Can a 100% rated HDL, HGL, HJL or HLL or JDL, JGL, JJL or JLL circuit breaker be installed into a J250AWK, J250DS, J250F, J250R, J250S or J250SS enclosure?
Circuit Breaker Enclosure
These enclosures have been tested and listed for use with standard rated (80%) breakers only. UPDATE January 2016: UL testing has been completed and 100% rated H or J frame PowerPact breakers are now acceptable in the J250 enclosures. When using 100% rated circuit breakers use only with 90 Degree C (minimum) rated conductors sized per ampacity of 75 Degree C rated conductors.
