Leviton 30/50 Amp Dual Power Angle Plug | 931-E

Product Overview

The Leviton Dual Power Angle Plug (Part No. 931-E) is a highly versatile, commercial-grade electrical connector designed to simplify installations for high-amperage equipment. Rather than requiring you to purchase separate plugs for 30-amp and 50-amp applications, this unique dual-configuration plug includes interchangeable solid brass blades directly in the box. By swapping the included blades, the plug can be configured as either a NEMA 6-30P (30A) or a NEMA 6-50P (50A) connection on the job site.

Encased in a tough, impact-resistant thermoplastic shell, the 931-E is built for rugged commercial environments. The plug's angled profile keeps heavy-duty cords lying flush against the wall, preventing the cord from bending sharply or protruding dangerously into the workspace. It is an industry standard for outfitting heavy 250V shop equipment like welders, large air compressors, and commercial kilns.

Key Features

• Dual Amperage Configuration: Each plug is supplied with both standard 30A blades and a flat 50A blade. This interchangeable design eliminates the need to stock multiple different high-amperage devices.
• Safety Rejection Feature: Built-in physical rejection safety mechanisms prevent the housing from closing if the internal blades are positioned incorrectly for the selected NEMA configuration.
• Heavy-Duty Thermoplastic Shell: The rugged black thermoplastic housing protects the internal wiring from impact, dirt, moisture, and chemical abuse commonly found in commercial shops.
• Hinged Shell Design: The shell and bottom are hinged at the front for incredibly fast, easy assembly and wiring access.
• Intuitive Wiring: Features deep-slotted, backed-out terminal screws and colour-coded terminals to ensure fast, secure, and accurate wiring of thick-gauge (14 to 6 AWG) conductors.
• Low-Profile Angle: The angled cable mount allows the heavy power cord to drop cleanly parallel to the wall, reducing strain on both the cord and the electrical receptacle.

Technical Specifications

Ideal Use Cases & Applications

• Welding Equipment: The NEMA 6-50P configuration is the universal standard for stud welders, MIG, TIG, and Stick welders in both home garages and commercial fabrication shops.

• Large Air Compressors: Highly effective for wiring large, stationary 250V air compressors that require a heavy-gauge, high-amperage power cord.

• Commercial Kilns & Ovens: Used for industrial heating elements and ceramic kilns requiring a reliable, high-temperature-rated power connection.

• Equipment Relocation: The interchangeable blades make it an excellent plug to keep in a service truck, ensuring you always have the right 30A or 50A connector on hand when modifying shop equipment cords.

Common Questions (FAQs)

Q: How do I switch the plug between 30 Amps and 50 Amps?
A: The package includes two sets of solid brass hot blades. To build a 30A (NEMA 6-30P) plug, insert the standard 30A blades into the designated slots. To configure it as a 50A (NEMA 6-50P) plug, swap in the included flat 50A blade according to the moulded instructions.

Q: Will this plug work for a 4-wire circuit (like a modern RV or generator)?
A: No. This is a 2-Pole, 3-Wire grounding plug designed for straight 250V applications (two hots and a ground). It does not have a neutral pin and cannot be used for 125/250V applications that require 4 wires (like NEMA 14-30 or 14-50 configurations).

Q: What size wire can the terminals hold?
A: The heavy-duty internal terminals are designed to securely clamp onto wire sizes ranging from 14 AWG all the way up to thick 6 AWG conductors.
