Pass & Seymour 5251 – Frequently Asked Questions

1) Is the Pass & Seymour 5251 a single receptacle or a duplex?
It's a single receptacle, one 15A 125V outlet per device rather than two. That's what you want on a dedicated branch circuit where only one piece of equipment should be plugged in, such as a panelboard-fed outlet for a single machine or appliance. If you need two outlets in the same opening, look at a duplex device like the Eaton Arrow Hart 5262W, also 15A 125V.
2) Can I back-wire the 5251 or do I have to use the side screws?
Both. The 5251 has internal screw-pressure-plate terminals plus two back wire holes, so you can side wire or back wire it depending on how much room you have in the box. Terminal screws ship backed out and are tri-drive steel, so a flat, Phillips or square driver all work.
3) Do I need a separate ground jumper when installing this receptacle in a metal box?
The 5251 includes an auto-ground clip that makes a positive ground connection through the mounting screw to a grounded metal box, so a bonding jumper isn't required for grounding through the strap. The strap itself is zinc-plated steel for corrosion resistance.
4) Will a 15A single receptacle work on a 20-amp circuit?
No, not as the only outlet. A single 15A receptacle on a 20A branch circuit is not permitted, because a single receptacle must have an ampere rating not less than the circuit. The 5251 is a 15A 125V device, so use it on a 15A circuit. On a 20A dedicated circuit choose a 20A device such as the Bryant 5362B heavy-duty 20A/125V receptacle.
5) Is spec-grade enough for a hospital or does it need to be hospital grade?
The 5251 is spec grade (heavy duty, commercial and industrial), not hospital grade. Patient care areas require hospital grade devices with the green dot. For those spaces use a hospital grade receptacle such as the Leviton 16262-HGW. The 5251 is fine for back-of-house, offices, shops and mechanical spaces in the same building.
6) Can I swap a 5251 straight in for a worn commercial single receptacle?
It's built for spec-grade replacements and retrofits, and it mounts on the standard strap with standard yoke screw spacing, so it drops into an existing single-gang box. Match ratings before you pull the old one: the 5251 is 15A 125V, so if what came out was a 20A device the circuit likely needs a 20A replacement instead.
7) What is the closest equivalent to the Pass & Seymour 5251 single receptacle from another brand?
The Pass & Seymour 5251 is a 15A 125V heavy-duty spec-grade single receptacle. The nearest cross-brand counterpart is the Eaton 6450W, a heavy-duty industrial specification grade decorator single receptacle that accepts #14-10 AWG conductors. Both are single-outlet spec-grade devices; the Eaton uses a decorator-style face, while the 5251 has a standard face and offers side wire or back wire terminations. Eaton's 816W is also a single receptacle rated 15A, built to commercial specification grade.
8) I need two outlets in the box instead of one at 15A 125V - what should I use instead of the 5251?
The Pass & Seymour 5251 is a single receptacle, so it gives one outlet per device. For two outlets at the same 15A 125V rating, the Eaton Arrow Hart 5262W is a heavy-duty industrial duplex receptacle, 15A 125V, NEMA 5-15R, in gray and built to industrial specification grade.
9) The circuit is 20A and the spec calls for a 5-20R - what replaces the 5251 there?
The Pass & Seymour 5251 is rated 15A 125V, so it does not serve a 20A 5-20R requirement. For 20A 125V devices, options include the Bryant 5362B heavy-duty duplex receptacle at 20A/125V, the Leviton 16352-1PW commercial grade heavy-duty straight blade duplex rated 20A 125V NEMA 5-20R, and the Leviton 16342 Decora Plus commercial grade duplex at 20-amp 125-volt NEMA 5-20R in white. The Bryant 21254IGO is a quad straight-blade NEMA 5-20R device at 20A if you need four outlets in one opening.
10) Will the 5251 work in a hazardous or wash-down location?
No. The Pass & Seymour 5251 is a standard-face spec-grade receptacle for commercial and industrial branch circuits and is not an enclosed or sealed device. For classified areas, the Appleton FSQC Series interlocked explosionproof receptacle or the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set are the appropriate device families.
11) What colors does the Pass & Seymour 5251 come in?
Two: black (5251) and ivory (5251-I). Both are the same 15A 125V spec-grade single receptacle with a matte finish, so pick by what the rest of the devices on the floor already look like.
12) Is the 5251 rated for unheated spaces like a parking garage or exterior mechanical room?
It is rated for continuous operation from -40C to +60C, which covers unconditioned and outdoor-adjacent interiors. Temperature rise is held to a maximum of 30C at full rated current after 50 cycles of overload at 150 percent of rated current. It still needs an enclosure suited to the location; the device rating isn't a weatherproof rating.
13) Is this receptacle UL listed for commercial code work?
The 5251 is cULus Listed, meaning it carries both US and Canadian listing marks. It is built in Mexico.
14) What size wall plate do I need for the 5251?
A single-receptacle plate, not a duplex plate. The device body measures 1.38 in wide by 1.08 in deep, and it mounts on a standard strap, so a standard single-gang single-receptacle plate covers it. A duplex plate will leave the opening wrong.
15) What is a lighter-duty alternative to the 5251 for a standard commercial office outlet?
The Pass & Seymour 5251 is built heavy-duty with a zinc-plated steel strap and one-piece brass triple-wire contacts. If the job only calls for commercial grade, the Leviton 16251W is a commercial grade heavy-duty impact-resistant straight blade receptacle, and the Eaton 816W is a commercial specification grade single receptacle at 15A. Both sit at commercial grade rather than the heavy-duty spec-grade build of the 5251.
16) Is the Pass & Seymour 5251 the right device for a 277V motor circuit or a 50A locking connection?
No. The 5251 is rated 15A 125V. For a 277V motor-duty application, the Bryant 430R9W is a 2-pole 3-wire 277V motor-duty receptacle. For a high-amperage locking connection, the Eaton 7379 is an industrial locking receptacle rated 50A at 600V/250V AC/DC in black, built extra heavy duty.
17) I need ivory devices to match the rest of the building - does the 5251 come in ivory, and what else does?
Yes. The Pass & Seymour 5251 single receptacle is offered as 5251-I in ivory and as 5251 in black. If the matching outlet needs to be a duplex, the Bryant 5362BI is a 20A/125V heavy-duty duplex receptacle in the ivory-suffixed version of that series.
18) What keeps the face from pulling off the body on a heavily used receptacle?
The strap tabs wrap around and lock down onto the face, which keeps the strap from separating from the face and back body under repeated plug pulls. Contact retention comes from one-piece brass triple-wire power contacts.
