Abb NC501SC-1 Nylon Snap-in Connector 1/2 in Nm Cable

Product Description

The ABB NC501SC-1 is a snap-in, nylon knockout connector sized at 1/2 inch, designed for securing non-metallic sheathed (NM) cable where it enters a junction box, panel, or enclosure. The connector provides a quick, tool-free installation by snapping directly into a standard 1/2-inch knockout opening. Nylon construction offers corrosion resistance and electrical insulation, making it suitable for dry residential wiring applications. Electricians and rough-in crews use this connector to protect NM cable sheathing from abrasion at box entry points and to maintain a secure, code-compliant cable termination.

This connector is intended for use with non-metallic sheathed cable in residential and light commercial electrical installations. It fits standard 1/2-inch knockout openings found in electrical boxes, enclosures, and load centers. The snap-in design speeds up installation during rough-in phases where high connector volume is common. It is sold individually, making it easy to order in exact quantities needed for a job.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements for cable securing and protection at box entry points. Power down the circuit and verify the panel or enclosure is de-energized before installing or removing connectors. Snap the connector firmly into the knockout until the retention tab seats fully, then feed the NM cable through and secure it per NEC cable stapling and support requirements. Do not use this connector with metallic-sheathed or armored cable types.
