Straight Blade Plug · 20A 250V NEMA 6-20P 2P3W grounding yellow vinyl body · Eaton 4509-BOX
Commercial grade straight blade plug rated 20A 250V with NEMA 6-20P configuration for 2-pole, 3-wire grounding connections. Yellow vinyl body helps with identification on cords and equipment in industrial and commercial service.
What this product is for
This straight blade plug is used to terminate portable cord on 250V equipment that requires a NEMA 6-20P connection. It is commonly selected for shop tools, HVAC service equipment, and other commercial or industrial loads matched to a 20A 250V branch circuit.
Use for
Use for 20A, 250V cord-connected equipment with a matching NEMA 6-20R receptacle. Suitable where a 2-pole, 3-wire grounding plug is required and a visible yellow body helps identify the cord end in service or maintenance areas.
Avoid for
Do not use on 125V circuits, twist-lock devices, or applications requiring a different NEMA pattern. Avoid using this plug where the equipment nameplate or local code requires a locking connector, watertight device, or a different amperage rating.
Best for
Best for electricians and maintenance teams replacing worn cord caps on commercial and industrial equipment using NEMA 6-20P straight blade connections.
Installed in
Typically installed on flexible cord serving portable or movable equipment in workshops, mechanical rooms, factories, and construction support applications.
Why this product exists
It provides a field-wireable replacement plug for 250V 20A equipment so damaged or worn cord ends can be replaced without changing the full cord set or equipment connection.
Compared with similar products
Compared with a locking plug, this straight blade style is faster to connect and compatible with standard NEMA 6-20R straight blade receptacles. Compared with lighter-duty cord caps, this commercial grade vinyl-bodied plug is intended for repeated service use. Typical circuit guidance: 20A branch circuits are commonly paired with #12 AWG conductors. Actual equipment and cord selection must match the device rating, cable type, and local electrical code.
