Hubbell 20 A 125 V Straight Blade Plug

The Hubbell straight blade plug is a commercial-grade receptacle rated for 20 A at 125 V AC. It features a standard duplex outlet with two poles and three wires for flush mounting. The gray nylon body uses side-wiring terminals for secure conductor connection. This component suits fixed wiring in commercial environments.

Suits 20 A commercial branch circuits

Electricians wiring 20 A branch circuits in offices, retail or light-industrial spaces will find the correct rating and mounting style. Installations that require tamper-resistant shutters, weather-resistant construction, surge suppression or a power indicator should select a different device. The plug is not corrosion resistant and lacks HP-rated motor switching beyond 1 hp.

20 A 125 V rating decides fit

The single specification that determines compatibility is the 20 A 125 V rating combined with the 5-20R configuration. Match this exactly to the circuit breaker and conductor size specified in the electrical design. Using the device on a circuit with a different voltage or amperage rating creates a safety hazard and violates electrical codes.

Questions about this item

Will the 20 A 125 V rating match the circuit breaker in my older workshop panel?

The device is rated for 20 A at 125 V AC, so it aligns with a standard 20 A single-pole breaker and 12 AWG wiring commonly found in older workshops.

How can I verify the duplex receptacle is wired correctly after installation?

Use a receptacle tester or multimeter to confirm 125 V between hot and neutral on each outlet, proper ground continuity, and correct polarity across both 5-20R slots.

Does the package include mounting screws and wire connectors, or must I supply them?

The receptacle itself is supplied; mounting screws and wire connectors are not included and must be purchased separately.
