Eaton 7765 – Frequently Asked Questions

1) What size cord can I land in the Eaton 7765 50A armored locking plug?
The clamp accepts cord outside diameters from 0.68 to 1.33 inches (17.3 to 28.6 mm), and the terminals take #10 through #6 AWG conductors. That covers most portable 50A feeder cord (SOOW type) in the 6/4 to 10/4 range. If your cord jacket is under 0.68 inches, the strain relief will not grip it properly.
2) Can this locking plug be used outdoors or in a cold storage / foundry environment?
The operating range runs from -40 to 90 degrees C (-40 to 194 degrees F), which covers freezer rooms, unheated yards, and hot process areas. The shell is stainless steel armor over a glass filled nylon face and body, and the contacts are zinc plated brass, so it holds up to impact and corrosion. Note that no dust-tight or watertight rating is claimed here; for a wet or washdown location the Pass & Seymour 267 Series rubber dust-tight locking plug is the type to look at.
3) How is the Eaton 7765 terminated, and does that change how much room I need behind the connection?
Termination is back wiring, so conductors land from the rear of the device rather than through side screws. The plug body measures 5.73 in long by 3.1 in wide by 2.68 in high, and you need straight pull-back room behind that for the cord and clamp when you assemble it.
4) Is an armored locking plug worth it over a standard industrial-grade plug?
The difference is the shell. This Eaton plug is an armored design with a stainless steel housing and an extra heavy duty device grade, built for cords that get dragged, dropped, and run over on a plant floor. Standard industrial-grade plugs like the Leviton L6-20P 20A 250V or the Bryant 7 Series non-metallic plug use a molded body and are rated industrial grade rather than extra heavy duty. If the connection lives in a fixed, protected spot, the lighter device is fine; if it is a portable machine feed taking abuse, go armored.
5) Is the Eaton 7765 locking plug approved for use in Canada?
It is CSA certified, which is the listing Canadian inspectors look for on a 50A industrial cord connection.
6) Can I use this plug on a 250 volt DC drive or battery circuit?
Yes. The Eaton 7765 carries a dual rating of 600 Vac and 250 Vdc at 50A, so it is usable on DC circuits up to 250 volts as well as AC industrial distribution. Many locking plugs carry no DC rating at all, so check the device you are replacing before you assume it is equivalent.
7) Which locking plug should I use for a wet or dusty outdoor feed instead of the Eaton armored plug?
The Pass & Seymour 267 Series rubber dust-tight locking plug is built as a dust-tight rubber-bodied device for that kind of service. The Eaton 7765 protects the connection differently: a stainless steel armored shell over a glass filled nylon face and body, with a -40 to 90 C (-40 to 194 F) operating range and a cord grip sized for 0.68-1.33 in cord diameters. Pick based on whether the exposure is mainly impact or mainly dust and moisture ingress.
8) Is a non-metallic locking plug like the Bryant 71020NP an equivalent to the Eaton 7765?
They are built for different exposure. The Bryant 71020NP is a 7 Series non-metallic locking plug, while the Eaton 7765 is an extra heavy duty armored device with a stainless steel shell and zinc plated brass contacts, back-wired for #10-6 AWG. Where the cord end takes impact or abrasion in an industrial bay, the armored body is the reason to specify the Eaton; where a non-conductive housing is preferred, the non-metallic body is.
9) What smaller-amperage locking plugs are available if 50 amps is more than my machine needs?
For lighter loads, ZenSupply carries the Bryant 4722N angle locking plug in NEMA L5-15P at 15A 125V, the Leviton 4570-C 2-pole L6-15P at 15A 250V, the Leviton L6-20P at 20A 250V, and a Leviton 4-wire 125/250V 3-phase 20A plug. Those are all standard NEMA configurations, so they will not interchange with the non-NEMA Eaton 7765 armored plug.
10) What is the Eaton part number for this armored locking plug?
The manufacturer part number is Eaton 7765. Spec it by that number when you are matching an existing armored non-NEMA connection, since the configuration will not cross to a NEMA catalog number.
