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.
2. Wire brush exposed conductor strandscompletely.
3. Apply a coat of oxide inhibiting compound(such as Fargo Mfg. Co. "Fargolene" orequiv.) to exposed conductor strands.
4. Insert the conductor into connector.Make sure all strands of conductor arecontained and tighten connector screw tospecified torque.
5. Check all connections and retightenas necessary. Compact combination meter socket with
