Cooper Wiring 20A Duplex Receptacle

This Cooper Wiring 877W-BOX is a commercial-grade duplex receptacle rated at 20 amps and 125 volts. It features a white finish and a galvanised steel mounting strap for corrosion resistance. The device meets all UL 498 requirements for safety and performance. Side-wire terminals accept up to #10 solid or stranded wire.

Suits standard 20-amp branch circuits.

This receptacle suits residential or commercial circuits requiring a 20-amp grounding outlet. It is not for circuits rated above 20 amps or for voltages other than 125 volts. Installers needing back-wire or push-in terminals should select a different model. The split-circuit tab allows separate control of each outlet where required.

20-amp 125-volt rating determines circuit fit

The 20-amp, 125-volt rating is the single specification that decides whether this receptacle matches the branch circuit. It must be installed on a 20-amp breaker with appropriate wiring. The UL 498 listing confirms compliance with the standard for attachment plugs and receptacles. Terminal screws are backed out and ready for #10 wire connection.

Questions about this item

Should I pick the 20 A 125 V white duplex or a different amp/volt combination?

Choose the 20 A 125 V white duplex when the circuit is rated for 20 amps at 125 volts; other amp/volt combinations serve different circuit ratings.

What does the 20 A 125 V rating mean once the receptacle is installed?

It means the outlet can safely carry up to 20 amps on a 125 volt branch circuit with proper wiring and breaker protection.

How does the side-wire terminal design affect the wire sizes I can use?

Side terminals accept up to #10 solid or stranded conductors, so larger gauges must be trimmed or a different termination method chosen.
