TERMINAL CONNECTOR TORQUE
Use the torque values shown for terminal connectors.
Refer to UL-486A, UL-486B, and UL-486E for
information on terminal connectors for aluminum
and/or copper conductors. 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.

associated with the conductor size. Slot width is the
normal design value. Slot length is to be measured at the
bottom of the slot.
