Abb Nc 051 Conduit Connector 1-1/2 in Trade Size

Product Description

The ABB INSTALLATION PRODUCTS nc 051 is a 2-screw clamp type conduit connector designed to join service entrance cable to a 1-1/2 inch knockout (KO) on an enclosure. Constructed from die cast zinc, it accepts cable with outside diameters ranging from 0.54 to 0.95 inches. The connector is not water-tight and is intended for dry or protected interior installations. Licensed electricians and electrical contractors install this connector during service entrance and panel work where a secure, code-compliant cable-to-enclosure termination is required.

This connector is suited for residential and light commercial electrical installations where non-metallic sheathed cable must be terminated at a 1-1/2 inch enclosure knockout. Typical applications include service entrance cable connections at load centers, sub-panels, and junction enclosures. The 2-screw clamp design provides a firm mechanical grip on the cable jacket without requiring special tooling beyond a standard flathead or nut driver.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify the absence of voltage before making any connections at the enclosure. Insert the connector into the knockout and secure the locknut firmly, then tighten both clamp screws evenly onto the cable jacket. This connector is not rated for wet or outdoor exposed locations and should not be used where water-tight termination is required.
