Pass & Seymour 5740 – Frequently Asked Questions

1) Can I use the Pass & Seymour 3870 on a 480V circuit?
No. It is rated 250V, so it belongs on circuits at or below that, typically 240V single phase or 208/240V three phase equipment. For a 277V or higher application you need a device rated for it, such as the Bryant 4750DR series 277V motor-duty receptacle or the Eaton 7379 industrial locking receptacle rated 600V/250V AC/DC.
2) Will this 3-pole 4-wire receptacle work for ordinary 120V office outlets?
No, and it is the wrong tool for that job. The 3870 is a 250V, 3-pole 4-wire industrial power connection for motors and machinery. For standard 125V convenience outlets use a commercial or industrial grade duplex, such as the Leviton 16352-1PW 20A 125V NEMA 5-20R or the Eaton Arrow Hart 5262W 15A 125V 5-15R industrial specification grade device.
3) If the equipment uses a twist-lock plug instead of straight blades, what 250V receptacle works?
The Pass & Seymour 3870 is a straight blade device, so it accepts only straight blade plugs. For a twist-lock connection at the same 250V level, the Eaton 7379 is an industrial locking receptacle rated 50A, 600V/250V AC/DC in black, with an extra heavy duty grade. Confirm the plug's NEMA locking configuration matches before ordering, since locking and straight blade bodies are not interchangeable.
4) What should I use instead of the Pass & Seymour 3870 for a standard 125V tool outlet?
The Pass & Seymour 3870 family is a 250V, 3-pole, 4-wire 15-R device for high-current equipment, not a general-purpose 125V outlet. For 125V work, the Bryant 5362B is a heavy-duty 20A/125V duplex receptacle, and the Eaton Arrow Hart 5262W is a heavy-duty industrial 15A 125V 5-15R single-phase device in gray. Those accept ordinary two-pole three-wire cord caps that will not mate with the 3870's 15-R face.
5) Can I put the Pass & Seymour 3870 in a hazardous location?
No. The 3870 is a cULus listed flush straight blade device for general commercial and industrial panel and equipment room wiring. For classified areas, Appleton builds purpose-rated hardware: the FSQC Series interlocked explosionproof receptacle, and the U-Line ECS factory-sealed 15 and 20 amp 3-pole plug and receptacle set. Match the device to the area classification on the drawing rather than substituting a general-purpose receptacle.
6) Is this receptacle approved for use in Canada?
Yes. The 3870 family carries cULus, UL, and CSA listings, so it is accepted on both sides of the border for commercial and industrial 250V work.
7) Does the Pass & Seymour 3870 mount flush in a wall box or does it need a surface enclosure?
It is a single flush receptacle, so it is designed to mount flush in a wall box or an equipment panel opening rather than in a surface-mounted housing. If the installation is an exposed or hazardous location, that calls for a different device entirely, for example the Appleton FSQC Series interlocked explosionproof receptacle.
8) I need a straight blade device rather than a twist-lock for motor equipment. Is this the right type?
Yes, if the equipment cord cap is a 15-R straight blade. Straight blade plugs in and out quickly with no twisting hardware, which suits machines that get connected and disconnected often. Where you want the plug to stay locked in under vibration or a cord pull, a locking device such as the Eaton 7379 industrial locking receptacle is the better choice.
9) What is the difference between the Pass & Seymour 3870 and a motor-duty receptacle like the Bryant 430R9W?
Both are intended for motor loads, but the pole counts and voltages differ. The 3870 is a 250V, 3-pole, 4-wire 15-R straight blade flush receptacle offered in 30A and 60A Motor FLA ratings. The Bryant 430R9W, series 4750DR, is a 2-pole, 3-wire 277V motor-duty receptacle. Pick by the system voltage and the number of current-carrying conductors at the opening.
10) Is the Pass & Seymour 3870 acceptable for patient care areas in a hospital?
The 3870 carries cULus, UL, and CSA listings but is a 250V 3-pole, 4-wire industrial power device. Patient care receptacles are specified as hospital grade: the Leviton 16262-HGW is a hospital grade duplex receptacle in white, supplied in packs of 100 for standardizing a wing or floor. Use the 3870 for equipment and mechanical rooms and the hospital grade device where the code calls for it.
11) I need a single flush outlet but on a 125V branch circuit. What is the closest alternative to the 3870?
The 3870's single flush body is 250V and 3-pole, 4-wire. If you want a single-outlet device on a 125V circuit, the Eaton 6450W is a heavy-duty industrial specification grade decorator single receptacle accepting #14-10 AWG, and the Eaton 816W is a commercial specification grade 15A single receptacle. Both are single-outlet devices like the 3870 but will not take a 15-R plug.
12) For a tenant build-out where I need several outlets at one box, is the 3870 the right choice?
No. The 3870 is a single flush 250V receptacle for one high-current equipment connection. For multiple outlets at one location, the Bryant 21254IGO is a quad straight-blade receptacle, NEMA 5-20R, 20A, and the Leviton 16352-1PW is a commercial grade heavy-duty straight blade duplex rated 20A 125V NEMA 5-20R. Use the 3870 only where a 15-R, 3-pole, 4-wire equipment cord lands.
13) How many of the Pass & Seymour 3870 receptacles come in a pack?
Packaging is 10 each, so a single order quantity covers a run of ten openings. Worth knowing if you are standardizing an equipment room or a machine line on one receptacle pattern.
14) Which receptacle holds up better in a high-abuse area than the Pass & Seymour 3870?
The 3870 is built for repeated use in commercial and industrial environments at 250V with cULus, UL, and CSA listings. If the abuse is in a 125V corridor or common area rather than at an equipment connection, the Leviton 16251W is a commercial grade heavy-duty impact-resistant straight blade receptacle, and the Bryant 5362BI is a heavy-duty 20A/125V duplex. Those address impact and traffic on standard circuits; the 3870 remains the device for the 15-R equipment feed.
15) Is there a decorator-style version of the Pass & Seymour 3870 to match our other device plates?
The 3870 is a flush single straight blade body in a 250V, 3-pole, 4-wire 15-R configuration and is not offered in a decorator opening. Where the finish plates need to match a decorator trim, the Leviton 16342 is a Decora Plus commercial grade duplex rated 20-Amp 125-Volt NEMA 5-20R in white, and the Eaton 6450W is an industrial specification grade decorator single receptacle. Those are 125V devices, so they cover the general outlets rather than the 250V equipment drop.
