Industrial 4-Wire Angle Plug

The Hubbell HBL8411C is a grounded straight-blade plug rated for 20 A at 125/250 V AC. It carries a NEMA 14-20P configuration with four blades and three poles for single-phase power. Industrial-grade construction and corrosion-resistant materials suit demanding equipment connections in workshops or commercial sites.

Screw-Terminal Wiring with Cable Limits

Installation uses standard screw terminals inside an angled housing that eases cable routing in tight spaces. The device accepts cable diameters from 0.39 in to 0.775 in; stripping to the correct length and tightening each terminal securely prevents loose conductors. The IP20 rating means the plug is not sealed against water or dust ingress.

NEMA 14-20P Configuration Decides Fit

The single specification that determines compatibility is the NEMA 14-20P blade pattern, which matches only receptacles with the same 20 A, 125/250 V rating. Buyers needing a different amperage, voltage, or blade arrangement cannot use this plug. No adapter changes the underlying NEMA standard.

Questions about this item

How can I confirm the HBL8411C plug is correctly wired after installation?

Verify that the four screw terminals match the NEMA 14-20P blade layout, then test for 125/250V AC continuity across the hot poles and ground with a multimeter before energising the circuit.

What comes with the HBL8411C and what must I supply separately?

The package includes the angled black/white housing with four screw terminals rated for 20 A; you must provide 0.39–0.775 in diameter cable and wire ferrules or stripped conductors for the terminals.

Which HBL8411C variant should I choose for a single-phase 20 A industrial circuit?

This model is the only version listed — NEMA 14-20P, 3-pole 4-wire, 125/250V AC, IP20, corrosion-resistant — so select it when those exact ratings match your equipment.
