Pass & Seymour 388 – Frequently Asked Questions

1) Is the Pass & Seymour 388 a 3-wire or 4-wire 30 amp receptacle?
Three-wire. The 388 is a 3-pole, 3-wire device in the 10-30R pattern: two hots and a neutral, with no separate equipment grounding conductor. If the job calls for a dedicated ground, you need a 4-wire 14-30R device instead.
2) Is the Pass & Seymour 388 acceptable in a hazardous or classified area?
The 388 is a UL Listed general-purpose surface receptacle, not a hazardous-location device. For classified areas, look to Appleton's FSQC Series interlocked explosionproof receptacle or the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set, which are built for that duty. Confirm the area classification with the engineer of record before selecting.
3) Can I use a 20A duplex receptacle instead of the Pass & Seymour 388 for a 30-amp appliance?
No. The 388 is rated 30A at 125/250V, while devices such as the Bryant 5362B heavy-duty duplex and the Leviton 16352-1PW commercial grade duplex are 20A 125V NEMA 5-20R. Those are single-voltage 20A devices and cannot serve a 30A dual-voltage appliance circuit.
4) Does the 388 receptacle need a recessed electrical box?
No. It is a surface-mount receptacle, so it mounts directly to a wall or other flat surface with the wiring brought to it, which is why it gets used in shops, mechanical rooms, and laundry areas where cutting in a flush box is not practical.
5) Can I run 240V equipment off the Pass & Seymour 388?
Yes, within 30 amps. The 388 is rated 125/250V, so it serves straight 240V loads across the two hot poles, or 120V loads from a hot to neutral, which is how dryers and some kitchen and shop equipment use the dual-voltage configuration.
6) Is the Pass & Seymour 388 UL Listed for commercial work?
UL Listed, yes. That is the certification carried on the 388 30A 10-30R surface receptacle, which is what inspectors look for on commercial kitchen, HVAC, and industrial machinery connections.
7) What is the difference between the 388 and a standard 20 amp straight blade receptacle like the Leviton 16342?
Different class of circuit entirely. The 388 is a 30A 125/250V 10-30R surface device for two-pole, dual-voltage loads. The Leviton Decora Plus 16342 is a commercial grade 20-amp 125-volt NEMA 5-20R duplex, a standard 120V general-purpose outlet. A 5-20R plug will not enter a 10-30R, and the two are not interchangeable on the same circuit.
8) I need a higher amperage industrial receptacle than 30A, what else is available?
The 388 tops out at 30 amps. For heavier loads, the Eaton 7379 industrial locking receptacle is rated 50A, 600V/250V AC/DC, in black, and is an extra heavy duty locking device rather than a straight blade. Note that a locking configuration requires a matching twist-lock plug, so the equipment cord cap has to change with it.
9) What is the difference between the Pass & Seymour 388 and the Bryant 430R9W motor-duty receptacle?
The 388 is a 30A 125/250V 10-30R straight blade surface receptacle, a 3-pole 3-wire device for dual-voltage equipment cords. The Bryant 430R9W is a 4750DR series 2-pole 3-wire 277V motor-duty receptacle, intended for 277V single-voltage motor loads. The pole-and-wire arrangement and voltage differ, so they are not interchangeable.
10) For a patient care area, should I specify the Pass & Seymour 388 or a hospital grade device?
The 388 is a UL Listed 30A 125/250V 10-30R surface receptacle for general power connections and carries no hospital grade designation. Where hospital grade is required, the Leviton 16262-HGW is a hospital grade duplex receptacle in white. Equipment needing a 10-30 connection in a healthcare building should be coordinated with the facility's electrical standards.
11) I need a surface-mounted outlet for shop tools but only 120V single-phase - is the 388 the right choice?
The 388 is a 3-pole, 3-wire 10-30R device at 125/250V, so a standard 120V tool cord will not plug into it. For straight 125V tool receptacles, Eaton's Arrow Hart 5262W is an industrial specification grade duplex rated 15A 125V 5-15R in gray, and the Leviton 16342 Decora Plus is a commercial grade 20A 125V NEMA 5-20R duplex. Those accept common 120V cord caps.
12) Does the Pass & Seymour 388 include a ground wire connection like a 4-wire dryer outlet?
The 388 is a 3-pole, 3-wire 10-30R configuration, which uses the older 3-wire arrangement rather than a separate equipment grounding conductor. If the branch circuit and cord are 4-wire, a 10-30R device is the wrong configuration and a 14-30 style receptacle should be specified instead. Verify the cord cap and circuit before ordering.
13) What color is the Pass & Seymour 388 and does it come in other colors?
Black is the finish, and model 388 is the single configuration offered under that part number. If a different device color is required to match other outlets in the space, you would be looking at a different catalog number rather than an option on this one.
14) What part number do I order for a Pass & Seymour 30A 10-30R surface receptacle?
Catalog number 388 from Pass & Seymour. One part number covers the device: 30A, 125/250V, 10-30R, black, surface mount, manufactured in China.
15) If I need a single receptacle rather than a duplex but at lower amperage, what are the alternatives to the Pass & Seymour 388?
The 388 is a 30A 125/250V single-outlet surface device. For lower-amperage single receptacles, Eaton offers the 6450W heavy-duty industrial specification grade decorator single receptacle accepting #14-10 AWG, and the 816W commercial specification grade single receptacle rated 15A. Both are 125V-class devices rather than dual-voltage 30A.
16) We need multiple outlets at one location - can the Pass & Seymour 388 do that?
No, the 388 is a single 10-30R outlet for one 30A equipment cord. Where several device openings are needed at one point, the Bryant 21254IGO is a quad straight-blade receptacle, NEMA 5-20R, 20A. That covers four 120V openings rather than one 30A dual-voltage connection.
17) Is there an impact-resistant option if the 388 location takes abuse from carts and equipment?
The 388 uses a durable black surface mount housing with no recessed box required. For 125V circuits in high-abuse areas, the Leviton 16251W is a commercial grade heavy-duty impact-resistant straight blade receptacle. It is a different configuration, so it is an option only where a 10-30 connection is not required.
18) Does color matter when matching the Pass & Seymour 388 to existing devices?
The 388 is supplied in black. Among comparable wiring devices, the Bryant 5362BI heavy-duty 20A/125V duplex and the Leviton 16262-HGW hospital grade duplex in white show how body colors vary by line, so confirm the color on each device when standardizing a facility. Color does not change the 388's 10-30R configuration or its 30A 125/250V rating.
