Pass & Seymour 5851-I – Frequently Asked Questions

1) Will the Pass & Seymour 5851 work for a 120V plug-in tool?
No. The 5851 single receptacle is rated 20A at 250V, so it is for 250V equipment only. Plugging a 120V cord cap into it is not the intended use, and the blade configuration on a 250V device will not accept a standard 125V plug. For 125V heavy-duty work, look at a 20A/125V device such as the Bryant 5362B duplex receptacle.
2) Is the Pass & Seymour 5851 rated for an unheated warehouse or a cold outbuilding?
Its operating range is -40 C to +60 C continuous, with a maximum 30 C temperature rise at full rated current. That covers unheated storage and most industrial ambient conditions. It is not an explosionproof or hazardous-location device, though. For a classified area you want something like the Appleton FSQC Series interlocked explosionproof receptacle.
3) What should I use instead of the Pass & Seymour 5851 for a 50A 250V machine?
The 5851 tops out at a 20A 250V rating. For a heavier machine feed, the Eaton 7379 is an extra heavy duty industrial locking receptacle rated 50A at 600V/250V AC/DC. It is a locking-style face, so the cord cap must be a matching twist-lock rather than the straight-blade plug the 5851 accepts.
4) What is the closest heavy-duty alternative to the Pass & Seymour 5851 if the equipment runs on 125V instead of 250V?
The Pass & Seymour 5851 is a 20A 250V single receptacle, so it will not serve a 125V cord cap. For 20A at 125V, the Bryant 5362B is a heavy-duty grade duplex receptacle rated 20A/125V, and the Bryant 5362BI is the same 20A/125V heavy-duty duplex in its own color version. Both give two outlets per opening rather than the single outlet the 5851 provides, so confirm whether the load needs a dedicated single.
5) Will the Pass & Seymour 5851 work in a hazardous or explosionproof location?
No. The 5851 is a cULus Listed spec-grade receptacle for general commercial and industrial boxes, with side wire and back wire terminations. For classified areas you need a purpose-built device such as the Appleton FSQC Series interlocked explosionproof receptacle, or the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set, which is a 3-pole plug-and-receptacle assembly rather than a flush wiring device.
6) The Pass & Seymour 5851 is rated 250V - does that mean it fits a 277V motor circuit?
No. The 5851 carries a 250V rating, so a 277V branch circuit is outside it. For that voltage the Bryant 430R9W, a 4750DR series 2-pole 3-wire 277V motor-duty receptacle, is the device built for the application. Verify the plug configuration on the motor cord before ordering, since motor-duty and straight-blade faces are not interchangeable.
7) Can I back-wire the 5851 or does it have to be side wired?
Both. The 5851 uses internal screw-pressure-plate back and side wire connections plus dual back wire holes, so you can bring conductors in from the side under the plate screws or straight into the back wire holes. Useful in a crowded box where a side-only device would fight you.
8) Do I still need a bonding jumper to the box with this receptacle?
The 5851 has an auto-ground clip that establishes a positive ground path to a properly grounded metal box through the mounting strap. Follow your local inspector and the NEC on whether a separate equipment grounding conductor to the device is also required for your installation type.
9) Is the Pass & Seymour 5851 approved for use in Canada?
It is cULus Listed, which covers both the US and Canadian listings, so it is acceptable for code-compliant installs on either side of the border.
10) How durable is the 5851 for a commercial kitchen where equipment gets unplugged constantly?
It is built for that kind of duty: a heavy-duty zinc-plated steel strap for strength and corrosion resistance, and one-piece brass triple-wipe power contacts for blade retention that holds up under repeated plug cycles. Typical uses include commercial kitchen equipment, industrial machinery, and workshop power distribution.
11) I need a single receptacle but only a 15A load - what can I use instead of the Pass & Seymour 5851?
The 5851 is a 20A 250V single receptacle. For a 15A single-outlet device, the Eaton 816W is a commercial specification grade single receptacle rated 15A, and the Eaton 6450W is an industrial specification grade decorator single receptacle that accepts #14-10 AWG conductors. Both keep the one-outlet configuration of the 5851 while stepping the amperage down.
12) I need more than one outlet on a 20A circuit - is there an alternative to the Pass & Seymour 5851?
The 5851 is a single-outlet 20A 250V device. If the requirement is multiple outlets on a 20A 125V circuit, the Bryant 21254IGO is a quad straight-blade receptacle, NEMA 5-20R, 20A, giving four outlets in one yoke. Note the change in voltage and face configuration - it will not accept a 250V plug.
13) How does the Pass & Seymour 5851 compare with the Eaton 5262 industrial duplex?
The Pass & Seymour 5851 is a heavy-duty spec-grade single receptacle rated 20A 250V with a zinc-plated steel strap, brass triple-wipe contacts and side wire terminations. The Eaton Arrow Hart 5262W is an industrial specification grade heavy-duty duplex rated 15A 125V with a 5-15R face in gray. They differ in outlet count, amperage, voltage and blade configuration, so the choice follows the cord cap and circuit, not the grade.
14) What colors does the Pass & Seymour 5851 come in?
Two order options, the base 5851 and the 5851-I, both ivory. Note that the spec sheet text for this heavy-duty spec-grade device also describes it as brown, so confirm the finish you need against the part number you are ordering if color matching matters on your job.
