Bryant 7 Series Locking Plug, NEMA Twist-Lock Configuration Family

The Bryant 7 Series Locking Plug is a family of twist-lock plugs engineered to deliver a secure, positive-locking power connection for demanding industrial and commercial electrical applications. This single product line spans 11 selectable NEMA locking configurations — 70620NP, NEMA L1-15P (125V, 15A), NEMA L5-20P (125V, 20A), NEMA L5-30P (125V, 30A), NEMA L6-15P (250V, 15A), NEMA L6-30P (250V, 30A), NEMA L7-20P (277V, 20A), NEMA L8-20P (480V, 20A), NEMA L8-30P (480V, 30A), NEMA L9-20P (600V, 20A), and NEMA ML-2P (125V, 15A Midget) — so contractors and facility managers can standardize on one trusted Bryant locking-device platform while matching the exact voltage and amperage pairing their equipment requires. Every configuration in the family is built as the plug end (the "P" designation), intended to mate with a corresponding Bryant locking connector or receptacle, and every configuration shares the same twist-lock engagement principle that resists accidental disconnection when equipment is subject to vibration, movement, or heavy daily use.

Bryant 7548 – Frequently Asked Questions

1) Which NEMA locking configurations does the Bryant 7 Series locking plug come in?
Eleven configurations, all plug ends: L1-15P (125V, 15A, part 7548), ML-2P midget (125V, 15A, 7594NP), L5-20P (125V, 20A, 70520NP), L5-30P (125V, 30A, 70530NP), L6-15P (250V, 15A, 70615NP), 70620NP, L6-30P (250V, 30A, 70630NP), L7-20P (277V, 20A, 70720NP), L8-20P (480V, 20A, 70820NP), L8-30P (480V, 30A, 70830NP), and L9-20P (600V, 20A, 70920NP). Pick by the voltage and amperage your equipment's cord and receptacle already use, since NEMA locking patterns are not interchangeable between configurations.
2) Is the Bryant 7 Series twist-lock a plug or a receptacle?
It is the plug end, the male device (the "P" in the NEMA designation). It goes on the cord and mates with a matching Bryant locking connector or receptacle of the same NEMA configuration. If you need the female end of the cordset, you want a locking connector rather than this device.
3) Will a Bryant locking plug mate with a Leviton or Pass & Seymour receptacle?
Yes, as long as the NEMA configuration is identical. NEMA locking patterns are standardized across manufacturers, so a Bryant L6-15P plug mates with any L6-15R receptacle, and a Bryant L8-20P works with the same pattern as a Pass & Seymour Turnlok L8 device. Match the configuration code, not the brand.
4) I need a 250V 20A twist-lock plug - the Bryant 7 Series jumps from L6-15 to L6-30. What do I use?
For an L6-20 opening, the Leviton 2321 is an industrial grade locking plug in NEMA L6-20P at 20A, 250V, which sits between the Bryant 70615NP L6-15P (250V, 15A) and the 70630NP L6-30P (250V, 30A). L6-20 blades will not engage an L6-15 or L6-30 receptacle, so match the receptacle configuration exactly rather than substituting by voltage alone.
5) Is the Bryant 70830NP the right plug for a 480V three-phase four-wire cordset?
No. The Bryant 70830NP is the L8-30P configuration at 480V, 30A, which is a two-pole three-wire pattern. For 480V three-phase 30A you want a plug built for that pattern - the Leviton 2341 is an industrial grade polarized locking plug in NEMA L16-30P, 480V 3-phase, 30A. The two patterns are not interchangeable at the receptacle.
6) The Bryant 7 Series tops out at 30A. What locking plug covers a 50A feed?
The Bryant 7 Series locking plugs span 15A to 30A across their eleven NEMA configurations. For a heavier feed, the Eaton 7765 is an extra heavy duty industrial armored locking plug rated 50A at 600V / 250Vdc with back-wiring terminations. That is a different device class from the 7 Series, so verify the mating receptacle is rated for the same amperage.
7) Can I use a locking plug on equipment that vibrates or gets dragged around?
That is what the twist-lock engagement is for. You insert and rotate, and the blades stay captive so the cord will not shake loose on a portable generator feed, a temporary power cordset, or a piece of shop equipment that moves. A straight-blade plug will back out under the same conditions.
8) What is the highest voltage locking plug in the Bryant 7 Series?
600V, on the L9-20P configuration (part 70920NP), rated 20A. Above that in the family are the 480V L8-20P and L8-30P. If you need 480V three-phase four-wire instead of the three-wire L8 pattern, the Leviton NEMA L16-30P 30A plug covers that configuration.
9) What is the ML-2P midget locking plug used for versus a standard L5-15?
ML-2P (Bryant 7594NP) is the miniature two-pole locking pattern rated 125V, 15A. It is a smaller body and a different blade pattern than the standard L-series, so it only mates with ML-2 connectors and receptacles. It shows up on small appliances, sound and lighting gear, and equipment where a full-size locking body will not fit. For a standard 125V 15A locking plug in the same family, use the L1-15P (part 7548).
10) I need a locking plug for a wet or wash-down area. Is the Bryant 7 Series the right choice?
The 7 Series is a general industrial and commercial locking plug, not described as a sealed device. Where you are hosing down equipment or working outdoors unprotected, look at a dust-tight rubber body instead, such as the Pass & Seymour 2675 267 Series 20A rubber dust-tight locking plug. For dry interior industrial, warehouse, and foodservice equipment connections, the 7 Series is the straightforward pick.
11) What is the difference between the 277V L7-20P and the 480V L8-20P Bryant plugs?
Both are 20A, but they are different voltage classes and different blade patterns, so they cannot be swapped. L7-20P (70720NP) is 277V, the single-phase leg-to-neutral voltage you see feeding commercial lighting off a 480/277 system. L8-20P (70820NP) is 480V, used line-to-line. Check the equipment nameplate voltage before choosing.
12) Can I use the Bryant 7594NP ML-2P in place of a standard L5-15 or L6-15 locking plug?
No. The Bryant 7594NP is the ML-2P midget configuration at 125V, 15A, and the midget pattern is physically smaller and will not mate with full-size locking receptacles. For a standard 125V 20A locking cord end use the Bryant 70520NP L5-20P, and for 250V 15A the Leviton 4570-C is an industrial grade NEMA L6-15P plug.
13) What is an alternative to the Bryant 70720NP for a 480V 20A locking plug?
The Bryant 7 Series covers 480V 20A with the 70820NP in NEMA L8-20P; the 70720NP is the 277V 20A L7-20P and is a different pattern. On the cross-brand side, the Pass and Seymour L720P Turnlok is a NEMA L8 three-wire 480V locking plug. Confirm the receptacle is L8 rather than L7 before ordering, since 277V and 480V twist-lock patterns are keyed differently.
14) For a wet or dusty location, is the Bryant 70620NP the right locking plug or should I use something else?
The Bryant 7 Series plugs are specified as twist-lock plug ends for industrial and commercial power connections. If the cord end is exposed to washdown or airborne dust, the Pass and Seymour 2675-2675 is a 20A rubber dust-tight locking plug from the 267 Series, built with a rubber body for that duty. Match the NEMA configuration of the dust-tight plug to the receptacle you are feeding.
15) How does the Bryant 70630NP compare with the Eaton L6-30 locking plug?
The Bryant 70630NP is the L6-30P plug end at 250V, 30A. The Eaton L6-30 locking plug is a two-pole three-wire nylon-bodied device in the same L6-30 series, listed at commercial grade. Both terminate a cord to an L6-30 receptacle; the Eaton is specified with a nylon body, while the Bryant is one of eleven configurations in a single 7 Series platform that lets a facility standardize stocking across voltages.
16) My cordset needs a 125/250V four-wire twist-lock plug. Does the Bryant 7 Series have one?
The Bryant 7 Series configurations run L1-15P, L5-20P, L5-30P, L6-15P, L6-30P, L7-20P, L8-20P, L8-30P, L9-20P, ML-2P and 70620NP. For a four-wire 125/250V pattern, the Leviton 2411 is an industrial grade four-wire locking plug rated 125/250V 3-phase 20A. Four-wire plugs will not seat in a three-wire receptacle, so confirm the outlet before ordering.
17) Can a facility standardize its locking plugs on one Bryant family?
That is the practical reason to buy the 7 Series. One family covers 125V through 600V and 15A through 30A across eleven patterns, so a maintenance shop can stock spares from a single line and keep consistent devices on cordsets throughout the building rather than mixing brands at every voltage.
18) Is there a locking plug with a grip-style body instead of a standard Bryant 7 Series plug for portable equipment?
The Bryant 7 Series locking plugs are standard male plug ends intended to mate with a matching Bryant locking connector or receptacle, and the 70520NP covers 125V 20A. If you want a gripping body on a frequently handled cord, the Eaton 7411-C is a safety grip locking plug rated 20A at 120/208V and listed as heavy-duty specification grade. Check the NEMA pattern against your receptacle, since the Eaton is a 120/208V device.
