Leviton 4760 – Frequently Asked Questions
1) What NEMA configuration is the Leviton 4760 locking receptacle, and what plug mates with it?
The Leviton 4760 is a NEMA L7-15R locking receptacle, rated 15A at 277V. Only an L7-15P twist-lock plug will mate with it. L7-15 is a two-pole, three-wire grounding configuration for 277V single-phase circuits, so a 125V L5-15 plug or a 250V L6-15 plug will not insert.
2) Can I use a 277V L7-15R receptacle on a 120V branch circuit?
No. The 4760 is configured and rated for 277V, which in practice means a line-to-neutral leg of a 480/277V system, typically feeding lighting circuits in industrial and commercial buildings. The L7-15 keying exists specifically to keep 277V equipment off 120V circuits and vice versa, so do not install it on a 120V branch as a general-purpose outlet.
3) I need a 20 amp locking outlet for a generator feed, is the 4760 the right part?
No. The 4760 is a 15A, 277V single-locking device, which is a lighting-circuit configuration rather than a generator inlet. For a 125/250V four-wire generator or portable equipment connection, look at a NEMA L14-20 device such as the Eaton L14-20 industrial locking receptacle.
4) What is the equivalent locking receptacle for a 125V single-phase L1-15 cord?
The Leviton 4760 is configured L7-15R for 277V service and will not accept an L1-15 plug. For an L1-15 two-wire locking cord, the Eaton 7540 NEMA L1-15 locking receptacle is the matching configuration; it is a commercial grade device, where the Leviton 4760 is built to an industrial grade standard with impact- and chemical-resistant housing. Confirm the circuit voltage before ordering either.
5) What locking receptacle should I use if my equipment cord is a NEMA L14-20 twist-lock instead of L7-15?
The Leviton 4760 is a NEMA L7-15R configuration rated 15A at 277V, so it only accepts an L7-15 plug - the blade pattern will not mate with an L14-20 cord. For an L14-20 twist-lock cord, use the Eaton L14-20 industrial locking receptacle (EAT-L1420-R), a black nylon device. NEMA locking configurations are keyed by design, so match the cord cap configuration exactly rather than trying to adapt.
6) Does this locking receptacle mount in a box or does it need a flanged housing?
The 4760 is a flush mount device, intended to sit flush to the mounting surface in a panel, enclosure, or wall box for a low-profile fit. If you need a receptacle that mounts to the outside face of an enclosure or a piece of equipment with a surface flange, that is a different style, for example the Bryant 71020ER 7 Series flanged locking receptacle.
7) Will a twist-lock receptacle keep equipment from unplugging itself?
That is the point of the single locking design on the 4760. The mating plug inserts and twists to lock into the contacts, so vibration, cord pull, or someone brushing past does not drop power to the load. It is the usual choice for 277V fixed and portable equipment in plants where a straight-blade outlet would shake loose.
8) I need a surface-mounted locking receptacle, not one that sits flush in a panel. What is the alternative?
The Leviton 4760 is a flush mount device intended to install flush to a panel, enclosure, or wall plate opening. If the installation calls for a flanged outlet mounted to the face of a box or machine housing, the Bryant 71020ER 7 Series flanged locking receptacle is the style to specify instead. Verify the NEMA configuration of the flanged unit matches your cord before ordering, since the 4760 is L7-15R.
9) Do I need an industrial grade locking receptacle, or will a commercial grade one do?
The Leviton 4760 is built to an industrial grade standard with an impact-resistant and chemical-resistant housing, which is the choice for plants where the device sees rough handling or contact with oils, solvents, and cleaning agents. The Eaton 7540 and the Eaton L14-20 locking receptacle are both commercial grade devices. For an office, light retail, or protected equipment room, commercial grade is the common specification; for a production floor or wash-down-adjacent area, the industrial grade construction is the reason to pick the 4760.
10) Can a Bryant 7 Series locking receptacle be swapped straight in for a Leviton 4760?
Not as a direct swap. The Bryant 71020ER is a 7 Series flanged locking receptacle, a different mounting style from the flush mount Leviton 4760. Two things have to line up for any substitution: the NEMA configuration must match the cord cap, and the body style must match the opening you already have cut. The 4760 is L7-15R, 15A, 277V, so a replacement has to carry that same configuration and be flush mount to drop into the existing prep.
11) What color is the Leviton 4760, and does it matter for identifying 277V circuits?
Black. Many facilities standardize on black-bodied locking devices for 277V lighting legs so maintenance crews can tell them apart at a glance from 120V devices, and the L7-15R keying enforces it mechanically regardless of color.
12) Where can I get the full wiring and dimensional spec for the Leviton 4760?
Leviton publishes a technical information sheet for the 4760 that ZenSupply hosts alongside the product, covering the detail beyond the headline 15A, 277V, L7-15R ratings. Use it when you need terminal and dimensional data for a panel cutout.
