Is this breaker compatible with a crouse hines panel board type g.

Is this breaker compatible with a crouse hines panel board type g.
Asked by: paul
Type QP breakers are not authorized for use in Crouse Hinds panels. Type MP-T Murray breakers are authorized for use in Crouse Hinds panels manufactured under UL file numbers E-26095 and E-13207. These file numbers normally appear on the equipment label. Type MP-T breakers may be used whenever the equipment labels specifies Types MP, MP-A, or MP-C breakers. A 40 Amp Double-Pole Type MP-T Circuit Breaker would be catalog number MP240. If you have any questions as to whether this breaker would be approved please provide the Crouse Hinds panel number and we can advise further.

Will This Fit In Square D Homeline ?

Will This Fit In Square D Homeline ?
Asked by: Joe
Hi Joe, It is not recommended that you "Mix and Match" circuit breakers by using one brand in another manufacturers panel. Using a Siemens type QP circuit breaker would not be listed as approved in a Square D Homeline panel. If your panel were to be inspected it would not pass.
