1 In addition to being ideally suited for residentialinstallations, these combination meter socketsmay be applied for rural service entrance, fortemporary construction site power distributionand for mobile homes. Consult your localdistributor for commercial or other installations.
60°C/75°C Wire RatingMurray circuit breakers, Style MP-T (through125 amp) are listed by UL for use with 75°Cwire, at the 75°C rating. This listing allows useof smaller wire sizes in many applications.Consult table #310 and Article #336-26 of the1993 N.E.C. for application details and limitations.
When using aluminum wire,the following procedure isrecommended:1. Strip insulation completely from end of
wire to desired length. Avoid nicking orringing wire.
