Frequently Asked Questions

What is a 3/8” Die Cast Screw-In Fixture Whip?

3/8” Die Cast Screw-In Fixture Whip is a pre-assembled electrical whip with solid THHN conductors and a die cast screw-in connector. It’s designed to quickly connect light fixtures to junction boxes in commercial, industrial, and institutional projects.

When should I use a Solid Wire Fixture Whip instead of a Stranded Wire Whip?

Solid wire whips are best for shorter runs and applications where conductors are less likely to be flexed repeatedly. They provide a stable, reliable connection for lighting installations in new construction and retrofit projects.

Yes. EPCO’s Solid Wire – 3/8” Die Cast Screw-In Fixture Whip is UL Listed (File E87199) and meets the 2026 National Electrical Code requirements: Articles 348.20(A)(2)(5), 348.22, 410.117(A)(B)(C), and 410.137(C).

What voltage applications are supported?

This fixture whip is available for 277-volt lighting applications, making it ideal for large commercial and industrial projects.

How does this product save labor time?

Each whip comes pre-cut, pre-stripped, and assembled with connectors, eliminating the need to cut and prepare conduit on-site — reducing labor hours and installation errors.
