Bryant 5666B 15A 250V Straight Blade Plug

The Bryant 5666B is a 15A, 250V straight blade plug built for dependable electrical connections in commercial, industrial, and residential settings. Featuring an S B (straight blade) configuration, this plug is engineered for quick, secure insertion into compatible straight blade receptacles rated for the same 15A, 250V circuit. As part of Bryant's professional-grade electrical device lineup, the 5666B delivers the precise fit and consistent function that electricians and maintenance teams rely on for everyday wiring, equipment hookups, and panel-to-load connections. Its straight blade design makes it a practical choice anywhere a fixed, non-locking plug connection at 15A and 250V is required.

Key Features

  • Amperage Rating: 15A, suited for standard-duty circuits and equipment that operate within this current range.
  • Voltage Rating: 250V, supporting applications that call for higher-voltage electrical service than typical 125V devices.
  • Straight Blade Configuration: The S B blade design allows for secure, compatible mating with correspondingly rated straight blade receptacles, without the twist-lock engagement of locking-style devices.
  • Model 5666B: Bryant's specific model designation, useful for accurate identification, cross-referencing, and like-for-like replacement in the field.
  • Bryant Manufacturing: Produced under the Bryant brand, a name electrical contractors and distributors commonly specify for wiring devices in professional installations.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Commercial and Industrial Electrical Installations — connecting cord sets and equipment to 15A, 250V circuits.
  • Equipment and Appliance Power Connections where a straight blade, non-locking plug is specified.
  • Replacement and Maintenance Wiring Projects that call for the Bryant 5666B by model number.
  • New Construction Electrical Systems requiring properly rated 15A, 250V cord-and-plug connections.
  • Panel, Load Center, and Branch Circuit Cord Connections in residential and light commercial settings.

Why Bryant?

Bryant is a recognized name in professional electrical devices, and the 5666B plug reflects that standard with a clearly defined 15A, 250V rating and a straight blade construction built for dependable circuit connections. Specifying components by model number, like the Bryant 5666B, helps contractors and facility teams ensure the correct amperage and voltage match on every connection. Choose the Bryant 5666B for consistent, precisely rated electrical components trusted by electrical contractors, maintenance professionals, and distributors across commercial, industrial, and residential projects.

Bryant 5666B – Frequently Asked Questions

1) Will the Bryant 5666B plug work on a 125V circuit or a standard 5-15 receptacle?
No. The Bryant 5666B is rated 15A at 250V and its straight blades mate only with straight blade receptacles rated for the same 15A, 250V service. A common 125V 5-15 outlet uses a different blade arrangement, so the plug will not insert. For a 15A 125V straight blade cord plug instead, the Eaton Arrow Hart Ultra Grip industrial specification grade plug covers that rating.
2) Can I use the Bryant 5666B on equipment drawing 20 amps?
No. The rating is 15A, so it must not be fitted to a cord set or load on a 20A circuit. For a 20A cord plug ZenSupply carries the Pass & Seymour EHU angled straight blade plug at 20A 125V, and the Leviton 8315-CT tamper-resistant hospital-grade plug in NEMA 5-20P.
3) What is the closest cross-brand equivalent to the Bryant 5666B 15A 250V straight blade plug?
The Leviton 5666-C is the closest match. It is a 3-wire 2-pole polarized industrial grade straight blade plug rated 250 volt 1-phase, which lines up with the Bryant 5666B's 250V straight blade, non-locking configuration. Both are cord-mounted plugs intended to mate with correspondingly rated straight blade receptacles.
4) Can a hospital-grade plug like the Leviton 8215-CAT be used in place of the Bryant 5666B?
No. The Leviton 8215-CAT is a tamper-resistant hospital-grade plug in NEMA 5-15P configuration, which is a 125V blade pattern and will not mate with the 250V receptacle the Bryant 5666B is built for. The 8215-CAT is the device to specify when a patient-care area calls for hospital grade at 125V; for a 250V straight blade connection, stay with the 5666B configuration. The Leviton 8315-CT is the NEMA 5-20P version of the same hospital-grade family.
5) Is the 5666B a locking plug or a straight blade plug?
Straight blade, non-locking. The blades push straight into the receptacle with no twist-lock engagement, so the cord can be pulled free without rotating the body. If the equipment needs a connection that cannot vibrate or be tugged loose, a straight blade device is the wrong choice and you want a twist-lock type instead.
6) Is a Bryant 5666B acceptable for patient-care areas in a hospital?
Not for patient-care spaces. Those locations call for hospital-grade devices, and the 5666B is a general 15A 250V straight blade plug. ZenSupply stocks hospital-grade options in the Leviton 8215-CAT tamper-resistant NEMA 5-15P and the 8315-CT tamper-resistant NEMA 5-20P, both supplied in packs of 100 for standardizing across a facility.
7) I need a plug that comes out of the wall flat behind equipment, is the 5666B angled?
The 5666B is a straight body plug, not an angle plug, so the cord exits in line with the blades and needs clearance behind the device. Where an appliance sits tight to the wall, an angled body is the better pick: ZenSupply carries the Leviton 275-E commercial grade 4-wire 3-pole straight blade angle plug and the Pass & Seymour EHU angled straight blade plug in 20A 125V.
8) What part number do I order to replace an existing Bryant 250V cord plug like for like?
Order by the model marking 5666B, which is the Bryant manufacturer part number for this 15A, 250V straight blade plug. Matching the model number is how you keep the amperage and voltage rating identical on a replacement, since straight blade configurations differ between ratings.
9) Is there a 20A straight blade plug alternative if the Bryant 5666B's 15A rating is too low for my equipment?
Yes. The Bryant 5666B is rated 15A, so equipment drawing more than that needs a 20A device. The Pass & Seymour PS5366-SSAN is an EHU series angled straight blade plug rated 20A 125V. Note it is a 125V device and angled rather than straight-bodied, so confirm both the voltage of your circuit and the cord entry orientation before substituting.
10) My equipment needs a 4-wire connection - will the Bryant 5666B work?
No. The Bryant 5666B is a 2-pole 3-wire style straight blade plug for a 15A 250V single-phase connection. For a 4-wire 3-pole cord end, the Leviton 275-E is a commercial grade 4-wire 3-pole straight blade angle plug. Count the conductors in your cord and confirm the receptacle's pole and wire configuration before ordering either.
11) If I want an angled cord entry instead of a straight body, what replaces the Bryant 5666B?
Angle-body plugs route the cord parallel to the wall, which helps behind equipment set close to a receptacle. Options include the Leviton 275-E commercial grade 4-wire 3-pole straight blade angle plug and the Pass & Seymour PS5366-SSAN EHU angled straight blade plug rated 20A 125V. Neither shares the Bryant 5666B's 15A 250V two-pole rating, so verify the receptacle configuration before substituting for cord orientation alone.
12) Where can I get the full wiring device specs for the Bryant 5666B?
Bryant publishes the device data in two references ZenSupply hosts: the Bryant Full Line Catalog and the Bryant Wiring Devices Selection Guide. Use the selection guide to confirm the blade configuration against the receptacle already installed before you wire up the cord set.
13) What is a lighter-duty cord plug option compared with the Bryant 5666B?
The Pass & Seymour PS5965-Y is a MaxGrip M3 nylon cord plug in yellow, a general cord-end device for field-assembled cord sets. The Bryant 5666B is a straight blade plug specifically rated 15A at 250V, which is the device to use when the connection has to match a 250V straight blade receptacle by rating. Choose based on the circuit rating and receptacle configuration you have to land on, not on body style alone.
