Plug Connector · 50A 125/250V NEMA 14-50P Straight Blade AutoGrip Gray · Eaton 5745N
Straight blade industrial plug rated 50A at 125/250V AC in NEMA 14-50P configuration. AutoGrip cord clamp and back-wire termination support #12-4 AWG conductors for range, dryer, generator and other heavy-duty cord-connected equipment where a 3-pole, 4-wire grounding plug is required.
What this product is for
This is a straight blade cord-end plug for 125/250V AC circuits rated 50A. It is used where equipment requires a NEMA 14-50P, 3-pole, 4-wire grounding connection.
Use for
Use for replacement cords or new cord sets on ranges, dryers, generators, welders, temporary power equipment, and other heavy-duty loads that are specifically designed for a 50A NEMA 14-50 connection. Back-wire terminals and the AutoGrip cord clamp help speed assembly in the field.
Avoid for
Do not use where a locking device is required, where the equipment nameplate calls for a different NEMA configuration, or where conductor size falls outside the listed cord range. Do not substitute this plug for 6-50, 10-50, or other non-matching configurations.
Best for
Best for electricians and maintenance teams needing a straight 50A 125/250V plug with a nylon body, grounding connection, and field-friendly cord grip for industrial or heavy residential equipment.
Installed in
Typically installed on flexible cord serving shop equipment, appliance cords, generator leads, and temporary power assemblies in commercial, industrial, agricultural, and residential service applications.
Why this product exists
It provides a safe, serviceable cord-end connection for equipment that needs two hots, one neutral, and one ground on a 125/250V 50A circuit. Typical branch-circuit guidance for 50A applications is larger than common 15A to 30A cord and receptacle circuits, so matching the exact device configuration and equipment rating is critical.
Compared with similar products
Compared with angled plugs, this straight plug suits installations with adequate cord clearance behind the equipment. Compared with locking connectors, it is intended for standard straight blade NEMA 14-50 receptacles. Always match plug and receptacle configuration exactly. Actual suitability depends on equipment rating, cord type, installation conditions, and local electrical code.
