Bryant BRY-7582-S – Frequently Asked Questions

1) Is the Bryant 3330 a grounding receptacle?
No. It is a 3-pole, 3-wire device, meaning three current-carrying poles and no separate equipment grounding contact. If your installation requires a grounding-type locking receptacle, you need a 3-pole 4-wire or 2-pole 3-wire configuration instead, depending on the system.
2) I am replacing an old 30A twist-lock outlet on a piece of shop equipment. Will the Bryant 3330 match my existing plug?
It will mate only if your existing plug is the same locking configuration, 3-pole 3-wire at 30A 250V. Locking blade patterns are configuration-specific, so a 3-wire plug will not seat in a 4-wire receptacle or the reverse. Check the pattern on the plug body before swapping the device.
3) Is there an equivalent 30A locking single receptacle from another brand that matches the Bryant 3330?
Yes. The Pass & Seymour Turnlok 30A non-NEMA single receptacle is the closest cross-brand counterpart: like the Bryant 3330, it is a 30A single locking receptacle rather than a duplex or straight-blade device. The Bryant 3330 is a 3-pole 3-wire locking device rated 30A at 250V. Because both are non-NEMA locking configurations, confirm the blade pattern of the mating plug or cord cap already in service before you swap one for the other - locking devices only mate within their own configuration, regardless of amp rating.
4) Can the Bryant 3330 be used in a hazardous or classified area?
The Bryant 3330 is a general commercial and industrial wiring device - a 3-pole 3-wire locking single receptacle rated 30A 250V for dedicated locking-device circuits and new construction. For a classified location you need a device built for it, such as the Appleton FSQC Series interlocked explosionproof receptacle, or the Appleton U-Line ECS factory-sealed 15 and 20 amp plug and receptacle set, 3-pole, where a factory-sealed assembly is called for. Those are purpose-built enclosure-type devices and are not interchangeable with a standard flush-mount locking receptacle.
5) What should I use instead of the Bryant 3330 if the circuit is 50A rather than 30A?
Step up to the Eaton industrial locking receptacle 7379, which is rated 50A at 600V/250V AC/DC in black and carries an extra heavy duty grade. The Bryant 3330 is rated 30A at 250V, so it should not be applied to a 50A branch circuit. Match the device to the breaker and the cord cap on the equipment: a 30A locking receptacle and a 50A locking receptacle use different blade configurations and will not intermate.
6) Do I need a locking receptacle like the Bryant 3330, or will a spec-grade straight-blade receptacle do?
The Bryant 3330 is a 3-pole 3-wire twist-lock device whose value is a mated plug that resists accidental disconnection under vibration or incidental pull, on a dedicated 30A 250V circuit. If the equipment cord has an ordinary straight-blade cap and no pull-out risk, a straight-blade spec-grade device is the simpler route - for example the Eaton Arrow Hart heavy-duty industrial duplex receptacle, 15A 125V, 5-15R in gray, or the Eaton commercial specification grade single receptacle at 15A. Those serve general 125V loads and cannot be used for a 30A 250V load or with a locking cord cap.
7) Why choose a twist-lock receptacle instead of a straight-blade 30A outlet?
A locking device keeps the mated plug mechanically engaged, so vibration or an incidental pull on the cord will not drop the connection. That is the reason to spec the 3330 on equipment circuits where an accidental disconnect matters. If your load is a general-purpose 15A or 20A convenience outlet, a straight-blade spec-grade device like the Eaton Arrow Hart 5262W (15A 125V, 5-15R) is the right part instead.
8) Which receptacles look like alternatives to the Bryant 3330 but will not work as substitutes?
Several spec-grade devices sit near it in a catalog but serve different circuits. The Pass & Seymour 5762 is a duplex self-grounding receptacle at 15A 277V; the Pass & Seymour IG5362-I is a heavy-duty spec-grade isolated ground duplex at 20A 125V; and the Pass & Seymour PLT26351 is a heavy duty spec grade plug load timer receptacle at 20A 125V. None of them is a locking device, and none matches the Bryant 3330's 30A 250V 3-pole 3-wire locking configuration - a twist-lock cord cap will not engage any of them.
9) Is the Bryant 3330 suitable for a 250V single-phase piece of equipment on a dedicated circuit?
Yes, that is exactly the application. Rated 30A at 250V and built as a single receptacle, it is meant for one dedicated load rather than shared convenience power. Common uses are commercial and industrial installations, device retrofits, and new construction.
