Cooper Wiring Devices Locking Flanged Inlet with Lid, Nylon

The Cooper Wiring Devices Locking Flanged Inlet with Lid is a rugged, back-wired power inlet built for industrial power distribution. Constructed of durable nylon and rated 50A, this armored-design flanged inlet accommodates #10-6 AWG conductors and cord diameters from 0.68 to 1.13 in, meeting California standard requirements in a non-NEMA configuration. It is engineered for demanding industrial environments where a secure, locking connection and a protective lid are essential.

Key Features

  • Durable Construction: Molded nylon housing resists impact and corrosion for long service life in industrial applications.
  • Back Wiring Method: Rear-terminal wiring accepts #10-6 AWG conductors for a secure, code-compliant hookup.
  • Electrical Rating: Rated 50A to support heavy industrial power loads.
  • Armored Design: Armored design type adds reinforced protection against impact and harsh job-site conditions.
  • Cord Diameter Range: Accepts cord diameters from 0.68 to 1.13 in for flexible cordset compatibility.
  • Non-NEMA Configuration: Built to California standard for specialized industrial connections outside standard NEMA configurations.
  • Integrated Lid: Hinged lid helps protect the inlet from dust and debris when not in use.
  • Steel Color Finish: Steel color coordinates with industrial equipment and enclosures.

Cooper Wiring Devices COOP3769 – Frequently Asked Questions

1) What size conductors can I land in this 50A Cooper flanged inlet?
The terminals accept #10 through #6 AWG, and it is a back-wired device, so conductors land on rear terminals rather than side screws. At 50A, #6 copper is the usual pull for the full rating. Plan your box depth around rear termination.
2) What cord diameter will the Cooper locking inlet's clamp accept?
Cord outside diameters from 0.68 to 1.13 inches. Measure the jacket OD on your existing cordset before ordering. A cord thinner than 0.68 inches will not clamp securely, and anything over 1.13 inches will not pass the strain relief.
3) Can a Bryant 70 Series flanged inlet be used as a drop-in replacement for the Cooper 3768?
Treat it as a different device rather than a drop-in. The Cooper Wiring Devices flanged inlet is a non-NEMA California standard nylon device accepting cord diameters from 0.68 to 1.13 in, while the Bryant 70520MB is a 70 Series NEMA locking-style flanged inlet. Because the mating configurations are not the same family, swapping one for the other means changing the cordset end as well.
4) Is this Cooper flanged inlet suitable for an outdoor generator connection?
It is built for industrial power distribution, with a nylon body and an armored design type for impact resistance, plus a hinged lid that keeps dust and debris out of the contacts when nothing is plugged in. Typical uses include generator and temporary power connections. The lid is a debris cover, not a stated weatherproof rating, so pair it with an enclosure appropriate to the location.
5) Flanged inlet or a receptacle for feeding power into equipment?
Use a flanged inlet when power flows INTO the equipment or panel through a cordset, which is why the pins are male and mounted behind a flange on the enclosure face. This Cooper unit is a 50A locking version, so the cord twists and locks rather than pulling free under vibration. A receptacle is the wrong part for that direction of feed.
6) What is the difference between the Bryant 70520MB and 71020MB flanged inlets when I am cross-shopping against the Cooper 50A inlet?
Both Bryant parts are flanged locking inlets, but they come from different lines: the 70520MB is a 70 Series device with a NEMA locking-style configuration, while the 71020MB is a 7 Series flanged locking inlet. The Cooper Wiring Devices inlet differs from both in that it is a non-NEMA California standard device rated 50A with an integral lid. Match the series and configuration to the existing plug rather than to the amperage alone.
7) I need a flanged inlet for a generator tie-in but my feeder is smaller than #6 AWG and I do not need a lid. What else should I look at?
The Cooper Wiring Devices inlet is built around back wiring for #10-6 AWG conductors with an armored body and a protective lid, which suits heavy industrial cordset work. If your job does not call for that termination range or the lid, the Bryant 71020MB 7 Series flanged locking inlet or the Bryant 70520MB 70 Series flanged inlet are simpler locking inlets to evaluate. Verify the configuration against the generator cordset in either case.
8) What colors does the Cooper locking flanged inlet come in and what are the part numbers?
Three choices: steel color as part 3768, black as 3769, and the standard version as CS8164. All are the same 50A locking flanged inlet with lid; pick the color that matches the rest of your equipment and enclosures.
