7.4 Terminal Connector Torque

Use the torque values shown in Figure 7-4 or Figure 7-5 for terminal connectors. Refer to UL-486A, UL-486B, and UL-486E for information on terminal connectors for aluminum and/or copper conductors. See Section 7.2, Electrical Connections, for information on the temperature rating of customer-supplied wire. Comply

with applicable national and local codes when installing a wiring system.

Note: If a connector has a clamp screw such as a slotted, hexagonal head screw with more than one means of tightening, test the connector using both applicable torque values provided in Figure 7-4.
