Blackburn CX 70-56 TNGS CU TPSCRW LUG STRT TANG No14-4 5/16

The CX 70-56 TNGS terminal lug takes conductors from #14 AWG up to #4 AWG. One conductor per lug, clamped by the set screw, so if you are landing anything larger than #4 you need a bigger frame size.

The CX 70-56 TNGS is a copper-bodied lug and should be used with copper conductor. If you are terminating aluminum or running a mixed copper-to-aluminum connection, you need a lug marked AL9CU or AL7CU-rated for dual use instead.

70 amps. That is the limit for the lug itself, so the conductor ampacity and the breaker ahead of it still govern the circuit. Within the #14 to #4 AWG range the lug covers, 70 A is the ceiling to size against.

It is a bare, uninsulated copper lug. Anywhere the termination needs covering, add heat shrink, a snap-on insulating cover or tape to suit the enclosure and voltage class. No insulation ships with it.

A set screw lug such as the CX 70-56 TNGS is the field-serviceable choice: no dies, no crimp tool, just strip the conductor, seat it and torque the screw, and you can back it out and re-terminate later. Compression lugs need the matching die and tool but give a permanent connection that does not want periodic retorque. For panel and control work where conductors get changed, the screw type is the practical pick.

The CX 70-56 TNGS has a straight (in-line) tang, so the conductor runs in the same plane as the bolt pad. That suits landing on a vertical bus face or a stud where the cable approaches head-on. If the conductor has to turn into the pad because of enclosure depth, a right-angle tang lug routes the wire with less bend stress.

Sold each, one lug per unit, so order one per conductor you are terminating plus spares. Nothing is bundled in a kit, and mounting hardware for the stud is not part of the lug.

Country of origin is the United States, which matters on federally funded and Buy American Act projects where domestic sourcing has to be documented on the submittal.
