Eaton AHCL620P – Frequently Asked Questions
1) What size wire can I land in this Eaton locking plug?
The Ultra Grip plug terminates #14 through #8 AWG conductors, so it covers everything from a 14 AWG portable cord up to 8 AWG on a 30 amp feed. Terminals are back wired, and the screws torque to 14-16 lbf-inch.
2) What should I use instead of the Eaton Arrow Hart locking plug if my opening is a 480V three-phase circuit at 30A?
The Eaton Arrow Hart line covers L15-30 and L6-30 configurations with a 250V rating, with a red 480-volt color-coded version offered in the L15 family. For a dedicated 480V three-phase 30A opening, the Leviton Industrial Grade Polarized Locking Plug, 480V 3-Phase, 30A NEMA L16-30P is built for that configuration. For a 3-wire 480V 30A cord, the Pass & Seymour Turnlok NEMA L8 locking plug is the L8 family equivalent.
3) What is the closest equivalent to the Eaton Arrow Hart AHCL620P locking plug from another brand?
The Eaton Arrow Hart AHCL620P is a nylon-bodied L6-30 industrial locking plug rated 250V. The nearest peer by family is the Leviton Industrial Grade Locking Plug in NEMA L6-20P, 20A 250V, which shares the two-pole 250V L6 family and industrial grade but is configured L6-20P rather than L6-30. Confirm the receptacle configuration in the field before swapping, since L6-20 and L6-30 blades do not intermate.
4) I need a locking plug for a 125V 15A cord, not 250V - what is the alternative to the Eaton Arrow Hart Ultra Grip?
The Eaton Arrow Hart Ultra Grip plugs are rated 250V in L6-30 and L15-30 configurations, so they will not serve a 125V 15A cord. The Bryant 4722N angle locking plug is NEMA L5-15P, 15A 125V, which is the correct configuration for that circuit.
5) What locking plug should I specify instead of the Eaton Arrow Hart if the cord connection is exposed to washdown or dust?
The Eaton Arrow Hart Ultra Grip plug has a nylon face and body rated for -40 to 60 C service, but it is a standard industrial locking plug rather than a sealed device. Where the connection sees dust or washdown, the Pass & Seymour 267 Series rubber dust-tight locking plug is built with a rubber body for dust-tight service.
6) Can I use this Eaton locking plug on outdoor or freezer equipment?
The nylon body is rated for service from -40 to 60 C (-40 to 140 F), so cold storage, unheated shops, and outdoor temporary power are within range. It is cULus Listed and RoHS compliant. Note that it is a general industrial plug, not a stated watertight or dust-tight device; for a wet or dusty location the Pass & Seymour 267 Series rubber dust-tight locking plug is the type to look at.
7) What does the color on the Eaton Arrow Hart locking plug mean?
Color is voltage identification, not cosmetic. The L15-30 plugs come black (AHCL1520P) and blue (AHCL1530P) at 250 volts, with red (AHCL1620P) marking the 480 volt device. On a facility where crews plug and unplug portable gear daily, that color coding is what keeps a 480 volt cord off a 250 volt machine.
8) Is nylon good enough for a plug that gets dragged around a plant floor?
Nylon face and body is the industrial-grade choice here, and the Ultra Grip design is built around a secure twist-lock mating with a 14-16 lbf-inch terminal torque. If you want a rubber body instead, for abuse resistance and dust-tight service, the Pass & Seymour 267 Series is rubber; Bryant's 71020NP is a non-metallic 7 Series alternative.
9) How big is this plug, for clearance behind a machine?
Body dimensions are 2.69 inches high, 2.1 inches wide, and 2.23 inches long/deep. Worth checking against a tight receptacle box or a panel with equipment pushed close to the wall, since the cord exits straight out the back.
