Bryant 4786MB 2-Pole 3-Wire Wiring Device Base, 15A 277V

The Bryant 4786MB is a 2-Pole 3-Wire (2P3W) wiring device base rated 15A at 277V, engineered to serve as the foundational connection point within a Bryant wiring device assembly. Built for grounded electrical circuits, this device base is sized for standard-duty branch circuit applications where a 15A, 277V rating is required. Electrical contractors, panel builders, and facility maintenance teams rely on Bryant device bases like the 4786MB for dependable, code-compliant wiring connections in commercial and industrial settings where consistent electrical performance is essential. Specifying the correct pole/wire configuration and voltage/amperage rating up front helps ensure the finished wiring device assembly performs as intended once installed.

Key Features

  • Pole/Wire Configuration: 2-Pole, 3-Wire (2P3W) design supports grounded circuit wiring, giving installers a defined conductor arrangement for safe, reliable connections.
  • Amperage Rating: Rated 15A, making this device base suitable for standard-duty branch circuit electrical loads commonly encountered in commercial wiring.
  • Voltage Rating: Rated 277V, suited to higher-voltage commercial and industrial electrical systems where 277V branch circuits are in use.
  • Device Base Construction: Functions as the base component of the wiring device assembly, providing the core wiring connection point that the rest of the 4786 series builds upon.
  • Model Designation: Bryant catalog number 4786MB clearly identifies this specific device base within the broader Bryant wiring device product line, simplifying specification and reordering.

Bryant 4786MB – Frequently Asked Questions

1) What voltage and amperage is the Bryant 4786MB rated for?
The Bryant 4786MB device base is rated 15A at 277V in a 2-pole, 3-wire configuration. That 277V rating is what puts it on commercial lighting and higher-voltage branch circuits rather than standard 120V receptacle circuits, so match the circuit voltage before you order it.
2) Can I use a 277V wiring device base on a 120V circuit?
No. The 4786MB is rated 277V, and that rating is the circuit it belongs on. For a 120V branch circuit you need a device rated 125V. Using the wrong voltage class device is a code and safety problem, not a convenience issue, so specify the rating against the circuit you are actually feeding.
3) What exactly is a wiring device base like the Bryant 4786MB, and is it a complete receptacle?
It is the base component of the device, the part that carries the wiring terminations and that the rest of the 4786 assembly builds on. On its own it is not a finished, ready-to-cover device. If you are replacing a complete receptacle or switch, order the full device rather than the base alone.
4) Does 2-pole 3-wire mean the Bryant 4786MB includes an equipment ground?
2-pole, 3-wire on the 4786MB means two current-carrying poles plus a third conductor for grounding, so it is intended for grounded circuit wiring. If your installation calls for a separate insulated equipment ground in addition to the circuit conductors, you are looking at a 3-wire grounding configuration, which this is not.
5) What part number do I reorder to match a Bryant 4786MB already installed in our building?
Order Bryant catalog number 4786MB. That single designation carries the 2P3W, 15A, 277V rating, so a facilities team standardizing across openings or panels can reorder from the number alone without re-verifying the electrical spec each time.
6) Is a 15A 277V Bryant device base suitable for commercial lighting branch circuits?
Yes, that is the usual home for it. 277V is the phase-to-neutral voltage on a 480/277V three-phase system, which is how most commercial and industrial lighting branch circuits are fed, and the 15A rating covers standard-duty loads on those circuits.
7) Where can I get the full Bryant spec sheet for the 4786MB?
Bryant publishes the 4786MB within its full line catalog, which ZenSupply hosts at zensupply.com/content/pdf/bryant/bryant-full-line-catalog.pdf. Use it when you need dimensional or terminal detail beyond the 2P3W, 15A, 277V electrical rating.
