B-LINE P3BFD3080 – Frequently Asked Questions
1) Will the B-Line P3BFD3080 plug-in unit work on a 480V three-phase busway run?
Yes. The P3BFD3080 is a three-pole plug-in unit for Pow-R-Way III busway, and its interrupting rating is published at three system voltages: 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac. On a 480V three-phase run you are working to the 25 kAIC figure, so confirm your available fault current at the tap point is at or below that before you hang it.
2) Does the P3BFD3080 bus plug fit any brand of busway, or only Eaton Pow-R-Way III?
Only Eaton Pow-R-Way III. This is a plug-in unit built to that busway's design, so it lands on Pow-R-Way III bus duct and nothing else. Plug-in units are not interchangeable between manufacturers or between busway generations, so if the run in your building is an older Pow-R-Way or another maker's duct, this is the wrong tap.
3) What size breaker is inside the P3BFD3080 bus plug?
An 80 amp, three-pole F frame breaker. The F frame covers 15 through 225 A, and this unit is factory built at the 80 A trip, so it suits a feeder or piece of equipment drawing up to 80 A continuous at the usual derating. If you need a different trip rating you order a different plug in the same F frame family rather than swapping the breaker in the field.
4) Do I need to run a separate ground conductor with a P3BFD3080 bus plug?
The plug is supplied with 50% integral/housing grounding, meaning the ground path is carried through the busway housing with a 50 percent rated integral ground rather than a full-size internal ground bus. Whether that satisfies your equipment ground depends on the grounding scheme of the Pow-R-Way III run it is stabbing into, so match the plug's grounding option to how the duct itself was specified.
5) Is the P3BFD3080 a circuit breaker I can mount in a panelboard?
No. It is a busway plug-in unit, an enclosed tap housing with an 80 A three-pole F frame breaker inside, made to stab onto a Pow-R-Way III run. It does not bolt into or clip into a panelboard or switchboard. For a panel you want a loose F frame breaker in the mounting style that panel takes.
6) What part number do I quote to match an existing 80A three-pole Pow-R-Way III plug?
B-Line P3BFD3080 is the manufacturer part number, an Eaton Pow-R-Way III plug-in unit with an 80 A three-pole F frame breaker. If the tag on the unit you are replacing reads P3BFD3080, this is a direct like-for-like. If it reads a different suffix, the digits after the frame letters are the trip rating, so check those before ordering.
