Hubbell HBL7513C Straight Blade Plug 50A Nema 10-50P

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL7513C is a straight blade male plug rated at 50 amps for use in single-phase, 3-wire, ungrounded electrical circuits. Built to the NEMA 10-50P configuration, it features a durable nylon body that resists dust, high temperatures, and impact — making it well-suited for demanding trade environments. This plug connects to 3-pole, 3-wire ungrounded wiring systems and is a standard field-wiring component installed by licensed electricians in both residential and light commercial settings.

The HBL7513C is designed for use with NEMA 10-50 receptacles, which are commonly found in applications such as electric ranges, large cooking appliances, and high-draw equipment that predates current grounding requirements. It is appropriate for retrofit and replacement work on older 3-wire ungrounded circuits where code compliance with the existing installation is maintained by the authority having jurisdiction. Licensed electricians and facilities technicians are the typical installers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify zero voltage at the wiring point before beginning any wiring work. Ensure conductor sizing matches the 50A rating of the plug. Ungrounded configurations are subject to specific NEC provisions — confirm with the authority having jurisdiction before installation on any new or modified circuit.
