Bryant 7 Series NEMA Flanged Locking Receptacle

The Bryant 7 Series flanged locking receptacle line delivers secure, twist-lock connections for demanding industrial and commercial power applications. This family of receptacles spans a range of NEMA locking configurations, including options such as NEMA L21-30R, so contractors and electricians can match the correct locking receptacle to the mating plug required on site. Each flanged body supports panel, box, or enclosure mounting, making the 7 Series a practical choice wherever a fixed, code-compliant locking connection point is needed rather than a portable cord-and-plug setup. As part of Bryant's professional-grade 7 Series locking device line, these receptacles are built for generator hookups, temporary power distribution, and industrial control applications where a standard straight-blade device is not secure enough.

Key Features

  • NEMA Locking Configurations: The 7 Series flanged receptacle family spans multiple NEMA locking configurations, including NEMA L21-30R, delivering a positive, twist-lock connection that resists accidental disconnection under load or vibration.
  • Flanged Mounting: The flanged receptacle body allows for surface, panel, or enclosure mounting at a fixed installation point rather than a portable cord connection.
  • 7 Series Construction: Part of Bryant's 7 Series locking device line, engineered for demanding industrial and commercial electrical applications.
  • Receptacle Function: Female (R) receptacle configuration provides the fixed connection point for a mating NEMA locking plug across the 7 Series configuration range.
  • Professional-Grade Design: The locking-style connection is intended for applications where a secure, pull-resistant connection point is required in demanding environments.
  • Panel-Ready Flange: The flanged housing is suited to mounting on equipment enclosures, distribution panels, or junction boxes throughout a facility.

Bryant 70520FR – Frequently Asked Questions

1) Which NEMA locking configurations does the Bryant 7 Series flanged receptacle come in?
The Bryant 7 Series flanged locking receptacle covers 36 NEMA locking configurations, from L5-20R and L5-30R (70520FR, 70530FR) right through L23-20R and L23-30R (72320FR, 72330FR). In between you get L6, L7, L8, L9, L10, L11, L12 (20A and 30A each), L13-30R, L14, L15, L16, L17-30R, L18, L19, L20, L21 and L22. Match the configuration to the mating plug already in service, since a twist-lock body only accepts its own NEMA pattern.
2) Will a Bryant 70520FR flanged receptacle accept a standard 5-20 straight blade plug?
No. The 70520FR is a NEMA L5-20R twist-lock device, so only an L5-20P locking plug will engage it. Straight-blade 5-20P cord caps will not insert or turn. If the equipment cord has a straight-blade plug, you need a straight-blade receptacle such as the Eaton Arrow Hart 5262W in 5-15R or a 20A spec-grade receptacle instead.
3) Which 7 Series part number do I need for a 3-phase 120/208V generator inlet?
For 120/208V wye three-phase with neutral and ground, the L21 pattern is the one to specify: 72120FR for L21-20R and 72130FR for L21-30R. If the generator is 120/240V single phase, L14 is the match instead (71420FR or 71430FR). Three-phase 250V without neutral uses L15 (71520FR, 71530FR).
4) I need a 50 amp locking receptacle. Does the Bryant 7 Series go that high?
No. The Bryant 7 Series flanged locking range runs 20A and 30A configurations only, the -20R and -30R patterns. For a 50A locking device, look at the Eaton industrial locking receptacle 7379, rated 50A at 600V/250V AC/DC.
5) For a hazardous or classified area, what should be used instead of a Bryant 7 Series flanged locking receptacle?
The Bryant 7 Series flanged locking receptacle is a general industrial and commercial twist-lock device for panel, box, or enclosure mounting, not a classified-area device. Where the area classification requires it, the Appleton FSQC Series interlocked explosionproof receptacle is the alternative, and the Appleton U-Line ECS factory-sealed 15 and 20 amp 3-pole plug and receptacle set is a factory-sealed option in the 15A and 20A range. Match the Appleton device to the class and division on the drawing.
6) What is the closest alternative to a Bryant 7 Series flanged locking receptacle if the load is 50 amps instead of 20 or 30 amps?
The Bryant 7 Series flanged locking receptacles cover 20A and 30A NEMA locking configurations, from NEMA L5-20R through L23-30R. For a heavier locking connection, the Eaton 7379 is an industrial locking receptacle rated 50A, 600V/250V AC/DC in black, built to an extra heavy duty grade. Confirm the mating plug's NEMA configuration before ordering, since the Eaton is a different amperage class and will not accept a 20A or 30A locking plug.
7) Is a Pass & Seymour Turnlok 3330 receptacle interchangeable with a Bryant 7 Series 30A locking receptacle?
No. The Pass & Seymour 3330 is a Turnlok 30A single receptacle in a non-NEMA configuration, so its blade pattern does not correspond to a standard NEMA locking layout. The Bryant 7 Series flanged locking receptacles use standard NEMA locking configurations such as L5-30R, L14-30R, and L21-30R, which mate with off-the-shelf NEMA locking plugs. Use the Bryant when the cord cap on site is a NEMA locking plug, and the Turnlok 3330 only where the existing equipment already uses that non-NEMA pattern.
8) What is the difference between a flanged locking receptacle and a standard locking receptacle?
A flanged body is made to be fixed in place. The flange bolts to a panel face, equipment enclosure, or junction box so the receptacle becomes a permanent power outlet, rather than hanging on the end of a cord. If you need the female end on a portable cord set instead, you want a connector body, not this flanged inlet-style device.
9) Do I get both the plug and the receptacle when I order a Bryant 70520FR?
You get the receptacle only. The 7 Series flanged device is the female (R) half, the fixed connection point in the panel or enclosure; the mating locking plug is ordered separately. If you want the plug and receptacle supplied together, the Appleton U-Line ECS factory-sealed 15 and 20 amp 3-pole set is sold as a plug and receptacle pair.
10) Why choose a twist-lock receptacle over a heavy-duty straight-blade one for equipment power?
The locking connection twists and latches, so load or vibration will not shake the cord loose, which is why these get used on generator hookups, temporary power distribution and industrial control work. A straight-blade device relies on blade friction alone. If the connection is not at risk of being pulled out, an industrial spec-grade straight-blade receptacle like the Eaton 6450W single receptacle (#14-10 AWG) or the Pass & Seymour IG5362-I 20A 125V duplex will do the job with easier cord caps.
11) Can I mount a Bryant 7 Series flanged receptacle on the side of a control panel or generator enclosure?
Yes, that is what the flange is for. The housing mounts to equipment enclosures, distribution panels or junction boxes, giving a fixed outlet point anywhere in the facility rather than a cord-and-plug arrangement.
12) Can I use a heavy-duty spec grade straight-blade receptacle instead of a Bryant 7 Series locking receptacle?
Only if the connection does not need to resist pull-out. The Bryant 7 Series is a twist-lock device intended for generator hookups, temporary power, and industrial control points where a straight-blade device is not secure enough. Straight-blade options include the Eaton Arrow Hart 5262W heavy-duty industrial duplex, 15A 125V, 5-15R in gray, and the Pass & Seymour IG5362-I heavy-duty spec grade isolated ground duplex at 20A 125V. Those accept standard cord caps but will not lock a plug in place under load or vibration.
13) I need a 277V receptacle - does the Bryant 7 Series cover it, or is there another option?
For a 277V locking connection, the Bryant 7 Series includes the NEMA L7-20R and L7-30R configurations, which are the 277V single-phase locking patterns in the line, supplied in a flanged panel-mount body. If the circuit instead calls for a straight-blade 277V device, the Pass & Seymour 5762 is a specification grade duplex self-grounding receptacle at 15A 277V. Choose the Bryant where the cord cap is a locking plug and the 5762 where it is not.
14) Does any comparable receptacle add load control that the Bryant 7 Series does not?
Yes. The Pass & Seymour PLT26351 is a heavy duty spec grade plug load timer receptacle rated 20A 125V, so it switches the load on a timer at the outlet itself. The Bryant 7 Series flanged locking receptacle is an unswitched twist-lock connection point for panel, box, or enclosure mounting, with no integral timing. Specify the PLT26351 for plug-load control requirements and the Bryant where a secure locking power tap is the objective.
