Hubbell Incorporated HBLMRGN Male Receptacle Green Double Set Screw 400 A

Hubbell 400 A Male Receptacle

The Hubbell HBLMRGN is a green, industrial-grade male receptacle rated for 400 A. It belongs to the Series 15 and Series 16 single-pole device family built for temporary power distribution. Typical users include crews running entertainment, theme-park, carnival or film-set electrical systems. The green housing provides quick visual identification on site.

Replaces worn single-pole contacts

This receptacle swaps out damaged or aged male contacts in existing Series 15 or Series 16 temporary power runs. The upgrade is worth it when the original locking screw or contact surfaces show heat damage, corrosion or mechanical wear that causes voltage drop. It restores a secure, low-resistance connection without replacing the entire cable assembly.

Tool-free assembly with retaining screw

Installation requires only the high-strength non-conductive retaining screw supplied with the device; no special tools are needed. The screw locks the contact securely into the insulated sleeve for reliable disassembly later. A common error is under-tightening the screw, which can lead to overheating under 400 A load. Always verify the screw is fully seated before energising the circuit.
