Overview

The ABB SRTC-050 nonmetallic threaded strain relief fitting (SKU: SRTC-050) is a UL-listed, CSA-certified solution designed for secure and reliable outdoor electrical installations. This 1/2-inch fitting features a durable gray nylon body with a zinc-plated steel locknut and neoprene O-ring, providing Type 3R (without O-ring/locknut) or Type 6P (with O-ring/locknut) environmental protection. The fitting includes four interchangeable elastomer bushings (grommets) in orange, yellow, black, and gray, accommodating a wide range of NM-sheathed cables (14/3, 12/3, 10/3, 14/2, 12/2, 10/2) and cord cables (0.240–0.450 inches in diameter). Engineered for temperatures up to 90°C (85°C with impact), the SRTC-050 ensures long-term performance in wet or corrosive environments. Ideal for use with Carlon PVC conduit systems, this fitting simplifies cable management while preventing strain and abrasion at entry points. The threaded design allows for quick installation and secure attachment to enclosures, junction boxes, or electrical panels. Packaged in a single-unit bag with 25 bags per outer carton (300 units total), the SRTC-050 is a cost-effective, high-utility solution for residential, commercial, and industrial electrical systems requiring durable, nonmetallic strain relief.

How to Install the SRTC-050 Nonmetallic Threaded Strain-Relief Fitting

This guide provides step-by-step instructions for installing the SRTC-050 strain-relief fitting for outdoor electrical installations.

Estimated time: 30m

Tools needed:

Screwdriver, Adjustable pliers, Wire strippers

Supplies needed:

Interchangeable elastomer bushings, Steel locknut, O-ring, Gland nut

  1. Select the appropriate bushing

    Refer to the provided chart to choose the correct elastomer bushing based on the type and size of the cable or cord being used.

  2. Insert the bushing and prepare the fitting

    Insert the selected bushing into the fitting and engage the gland nut without tightening it.

  3. Install the fitting

    For knockout installation, install the smaller O-ring on the connector, insert the connector into the knockout, and tighten it with the steel locknut.

  4. Pass the cable through the fitting

    Pass the cable or cord through the fitting to prepare for securing it.

  5. Secure the cable

    Tighten the gland nut using adjustable pliers or by hand until the bushing is flush with the gland nut's outer surface. Do not exceed a torque of 110 lbf-in (12 N·m).

  6. Disconnect power supply

    Ensure that the power supply is disconnected before starting the installation to avoid electrical hazards.
