Leviton Mfg Co R20-05378-P00 Welder Outlet 50A 250V Nema 6-50R

Product Description

The LEVITON MFG CO R20-05378-P00 is a surface-mount grounding outlet rated at 50 amps and 250 volts, designed specifically for welder applications. It uses a 2-pole, 3-wire configuration and carries a NEMA 6-50R receptacle designation. The outlet is UL listed and accepts both aluminum and copper conductors up to a maximum of 4 AWG. At 2.15 inches in diameter, it is compact enough for surface installation in shop environments, garages, and industrial spaces. Electricians install this outlet as a dedicated welder circuit termination point.

This outlet is used in residential garages, commercial shops, and light industrial settings where a dedicated 240-volt welder circuit is required. Its NEMA 6-50R configuration matches the plug type found on most MIG, TIG, and stick welders drawing up to 50 amps. The surface-mount design simplifies installation on finished walls or enclosures without requiring a recessed box, making it a practical choice for retrofit welder circuits and new construction alike.

Key Features

• NEMA 6-50R configuration rated for 50 amps at 250 volts

Compatibility

Designed as a NEMA 6-50R surface-mount replacement or new-installation outlet for dedicated 50-amp, 250-volt welder circuits.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit at the panel and verify zero voltage with a meter before wiring. A dedicated 50-amp, 240-volt circuit with appropriately sized overcurrent protection is required. Do not exceed the 4 AWG maximum conductor rating or connect to circuits with aluminum wiring without confirming the terminal rating and using the appropriate anti-oxidant compound.
