Wire Gauges And Tightening Torque - TECO A510s Series Instruction Manual

3.6 Wire Gauges and Tightening Torque

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