Bryant 70 Series Flanged Inlet, NEMA Locking-Style Configuration

The Bryant 70 Series Flanged Inlet is a locking-style flanged inlet engineered for secure, twist-lock power connections in permanent and semi-permanent distribution setups. This listing covers the 70 Series flanged inlet platform across multiple Model options and NEMA locking configurations, including the L8-30P configuration, giving installers a range of choices to match their corresponding locking plug or connector. Flanged inlets mount directly to an enclosure, panel, or equipment housing, allowing a mating locking device to connect and disconnect quickly while resisting accidental separation during use. As part of Bryant's established 70 Series locking device line, these flanged inlets are built for professional electricians and facility maintenance teams who need a dependable, code-compliant connection point for power equipment.

Key Features

  • Locking-Style Configuration: NEMA locking-style configurations, such as the L8-30P, provide a secure mating connection with the corresponding plug or connector, helping prevent accidental disconnection during use.
  • 70 Series Design: Engineered as part of Bryant's established 70 Series locking device line, built to deliver dependable performance for demanding power connection applications.
  • Flanged Inlet Style: The flange-mount design allows the inlet to be securely mounted to a panel, enclosure, or equipment housing, creating a fixed, reliable point of connection.
  • Secure Power Connection: The locking design helps maintain a stable connection under vibration and movement, reducing the likelihood of unexpected disconnects in demanding environments.
  • Multiple Model Options: Offered across 11 Model configurations (70520MB through 70930MB) within the 70 Series line, covering a range of NEMA locking configurations to match different mating devices.
  • NM Configuration: These flanged inlets are cataloged under Bryant's NM configuration within the 70 Series product family.

Bryant 70615MB – Frequently Asked Questions

1) What NEMA locking configurations does the Bryant 70 Series flanged inlet come in?
Eleven locking configurations across the 70 Series flanged inlet line, all male-pin inlets: NEMA L5-15P (70615MB), L5-20P (70520MB), L5-30P (70530MB), L6-20P (70620MB), L6-30P (70630MB), L7-20P (70720MB), L7-30P (70730MB), L8-20P (70820MB), L8-30P (70830MB), L9-20P (70920MB) and L9-30P (70930MB). Pick the one that matches the mating locking connector or cord already in service, since NEMA locking blades only mate within their own configuration.
2) I need a 480V 30A generator connection point on an enclosure. Which Bryant 70 Series inlet is that?
That is the NEMA L8-30P version, Bryant 70830MB. L8-30 is the 3-wire, 2-pole 480V 30A locking configuration, so it takes an L8-30 locking connector on the feeder. If the load is 600V instead, step up to the L9-30P (70930MB); at 250V use the L6-30P (70630MB).
3) Is a flanged inlet the right part for a generator hookup, or do I need a power outlet receptacle?
A flanged inlet is what you use when power is coming INTO the equipment or panel: it presents male pins on the outside of the housing and accepts a locking connector on the end of a cord, which is exactly the arrangement for feeding a building panel or a piece of equipment from a portable generator. A flanged outlet (female receptacle) is the opposite case, where power leaves the enclosure and a locking plug on the load cord plugs into it. Match the gender to the direction of power flow, not to what is convenient to mount.
4) What is the difference between the L5, L6, L7, L8 and L9 versions of this Bryant inlet?
They are different voltage classes, and the blade patterns are deliberately not interchangeable. L5 is 125V, L6 is 250V, L7 is 277V, L8 is 480V and L9 is 600V; all five of those are 2-pole, 3-wire grounding configurations. The number after the dash is the ampere rating, and the 70 Series flanged inlets cover 15A (L5 only), 20A and 30A. So a 277V lighting or HVAC circuit wants the L7 version, while a 480V three-wire feed wants the L8.
5) Will a twist-lock inlet hold up on portable equipment that vibrates or gets dragged around?
That is the reason to use the locking style. The twist-lock interface on the 70 Series inlet keeps the connection engaged under vibration and movement instead of working loose the way a straight-blade connection can, so it suits portable power gear, job site and event temporary power, and standby generator tie-ins. The flange mount itself is fastened through the enclosure wall, so the cord load is taken by the housing rather than by wiring inside.
6) Do I need a separate box or cover to install the Bryant 70 Series flanged inlet?
The inlet is a flange-mount device: it fastens to the face of a panel, enclosure or equipment housing through a cutout, so the enclosure is the box. You still need the right cutout and mounting screw pattern for the configuration you order, plus a weatherproof cover or gasket if the mounting surface is outdoors or wet location. The inlet does not come with an enclosure of its own.
7) Can I use one of these inlets to replace a straight-blade inlet on my equipment?
Not as a direct swap on the cord side. Every 70 Series flanged inlet here is a locking twist-lock device, so the mating cord end has to be a locking connector of the same NEMA configuration; a straight-blade cord will not engage. If you are converting a piece of equipment from straight-blade to locking, plan on changing the cord connector at the same time and on verifying the new flange cutout against the old opening.
8) For a multi-building standby generator program, can I standardize on one Bryant 70 Series inlet across sites?
You can standardize by voltage class rather than by part sprawl, which is the usual approach for a facilities fleet. The 70 Series flanged inlet line runs from 70520MB up through 70930MB in one family, so 208/240V single-phase sites can sit on the L6-30P (70630MB) and 480V sites on the L8-30P (70830MB), with the same series, same mounting style and the same twist-lock discipline for the portable cord sets. Keeping the cord tails in matching configurations is what makes the generator interchangeable between buildings.
