Wire Gauges and Tightening Torque

To comply with UL standards, use UL approved copper wires (rated 75° C) and round crimp terminals (UL List-
ed products) as shown in table below when connecting to the main circuit terminals. Gefran recommends using
crimp terminals manufactured by NICHIFU Terminal Industry Co., Ltd and the terminal crimping tool recom-
mended by the manufacturer for crimping terminals and the insulating sleeve.
