Pass & Seymour 3852 – Frequently Asked Questions

1) Will a NEMA 6-50 welder plug fit the Pass & Seymour 3852 receptacle?
Yes. The 3852 is a 6-50R straight blade device, 50A at 250V, 2-pole 3-wire, so any cord set with a matching NEMA 6-50P plug lands in it. That is the configuration most stick welders and plasma cutters ship with. It will not accept a 6-30P, a 14-50P range plug, or any locking (twist-lock) plug.
2) Does the 3852 receptacle mount in a flush wall box or on the surface?
It is a surface-mount device. The housing mounts directly to a wall, panel, or enclosure face, so there is no flush box or ring prep to cut in. If your drawing calls for a flush-mounted 6-50R behind a plate, this is the wrong body style.
3) Is the Pass & Seymour 3852 a 3-wire or 4-wire receptacle, and does it have a neutral?
Two-pole, three-wire: two hots and an equipment ground, no neutral. That suits 250V single-phase loads that need no 120V leg, such as welders, compressors, and HVAC equipment. Any appliance needing 120/240V (a range or dryer with controls on a neutral) requires a 4-wire device like a 14-50R instead.
4) If equipment needs a twist-lock connection instead of a straight blade at 50 amps, what receptacle works?
The Pass & Seymour 3852 is a straight blade 6-50R rated 50A 250V, so the plug pulls straight out under load. Where a locking connection is wanted at the same amperage, the Eaton 7379 is an industrial locking receptacle rated 50A at 600V/250V AC/DC in black, classed extra heavy duty. The locking body requires a matching locking plug on the cord, so it is not interchangeable with a 6-50P cord cap.
5) Can I use a 20A duplex receptacle for a 250V welder circuit instead of the 3852?
No. The Pass & Seymour 3852 is rated 50A 250V in a 2-pole 3-wire 6-50R configuration, which is what a 250V welder cord cap mates with. Devices such as the Bryant 5362B heavy-duty duplex receptacle at 20A/125V or the Leviton 16352-1PW commercial grade duplex at 20A 125V NEMA 5-20R are 125V 20-amp duplex devices with a different blade pattern and a much lower current rating, so they will not accept a 6-50P plug.
6) Is the 3852 receptacle approved for use in Canada as well as the US?
It is cULus Listed, which covers both US and Canadian requirements, so it can be specified on either side of the border without a second listing.
7) How much clearance do I need to mount the 3852 50A receptacle?
Plan for a footprint of 5.65 in high by 2.8 in wide, with 2.41 in of depth off the mounting surface. Add room above and below for the cord to bend once a 6-50 plug is seated, which adds several inches in practice.
8) Can I use the Pass & Seymour 3852 on a 120V circuit?
No. It is rated 250V, and the 6-50R blade pattern is a two-hot 250V configuration that will not accept a 120V 5-15P or 5-20P plug. For 125V work you need a 5-15R or 5-20R device, for instance the Leviton commercial grade 20A 125V 5-20R duplex.
9) What should I specify for a 50A connection in a hazardous or classified area?
The Pass & Seymour 3852 is a cULus Listed surface-mount thermoplastic receptacle intended for general industrial, commercial kitchen, HVAC and workshop power connections, not for classified locations. For a classified area, the Appleton FSQC series interlocked explosionproof receptacle is built for that duty, and the Appleton U-Line ECS factory-sealed plug and receptacle set covers 15 and 20 amp 3-pole connections. The Appleton devices use their own enclosure and plug system rather than a standard 6-50P cord cap.
10) The 3852 is 250V 2-pole 3-wire. What do I use for a 277V motor load?
The Pass & Seymour 3852 carries a 250V rating, so it is not the device for a 277V branch. The Bryant 430R9W, a 4750DR series 2-pole 3-wire motor-duty receptacle, is rated 277V and shares the 2-pole 3-wire configuration. Confirm the amperage and plug pattern against the motor cord, since the two are not the same NEMA configuration.
11) I am standardizing patient-care room outlets and 50A equipment drops in the same building. Do I need two different devices?
Yes. The Pass & Seymour 3852 covers the 50A 250V 6-50R equipment drops and is cULus Listed for US and Canadian installations. Patient-care receptacles call for a hospital grade device such as the Leviton 16262-HGW hospital grade duplex receptacle in white; general corridor and office outlets are commonly handled with commercial grade devices like the Leviton 16342 Decora Plus 20-amp 125-volt NEMA 5-20R duplex. The three serve different circuits and are not substitutes for each other.
12) What is the 3852 receptacle housing made of, and will it hold up in a shop?
The body is thermoplastic in black. It is built for high-amperage distribution in industrial and commercial work, with typical uses including welders, workshop tools, HVAC gear, and commercial kitchen equipment. For a hazardous or classified area it is not the right device: an explosionproof unit such as the Appleton FSQC Series interlocked receptacle covers that.
13) Will the 3852 work for a generator inlet or transfer setup?
It is listed for generator transfer applications among its typical uses, and at 50A 250V 2-pole 3-wire it matches 6-50 generator cord sets. Note that it is a receptacle, not a power inlet box, and it carries no neutral, so a transfer scheme needing a 120/240V four-wire connection will not work with it.
14) Is a single industrial specification grade receptacle an alternative to the 3852 for a kitchen appliance?
Only if the appliance is a 125V cord-and-plug load. The Pass & Seymour 3852 is a 50A 250V 6-50R surface receptacle with a black thermoplastic housing for heavy-duty equipment. The Eaton 6450W is a heavy-duty industrial specification grade decorator single receptacle accepting #14-10 AWG, and the Eaton 816W-BOX is a commercial specification grade single receptacle rated 15A; both are low-current 125V devices. Match the appliance nameplate and cord cap before choosing.
15) What do I use where a workbench needs several 20A outlets rather than one 50A drop?
The Pass & Seymour 3852 provides a single 50A 250V 6-50R connection for one heavy-duty tool or welder. For multiple hand-tool outlets, the Bryant 21254IGO is a quad straight-blade receptacle, NEMA 5-20R, 20A, and the Leviton 16251W is a commercial grade heavy-duty impact-resistant straight blade receptacle. Those are 125V 20-amp devices and will not serve the 250V equipment the 3852 is intended for.
