B-LINE P3BEHD3090 – Frequently Asked Questions
1) What amperage is the B-Line P3BEHD3090 busway plug-in unit rated for?
The P3BEHD3090 plug-in unit carries a 90 amp circuit breaker on an E frame, which covers the 15 to 225 amp range. If your tap load is above 90 amps continuous, you need a different unit in the series rather than this one.
2) Will a 90A Pow-R-Way III plug-in unit meet my available fault current at 480V?
Interrupting rating on this unit is 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. Compare that against the available fault current at the busway tap point on your coordination study. If your 480V system calculates above 14 kAIC at that point, this breaker is not adequately rated and you need a higher AIC device or series-rated combination.
3) What grounding does the B-Line P3BEHD3090 plug-in unit provide?
It uses 50% integral housing grounding, meaning the ground path is carried through the busway housing itself at 50 percent capacity rather than through a separate full-size ground bus. Make sure the run it plugs onto is the matching 50% integral ground configuration, since mixing ground schemes on a Pow-R-Way III run is not a valid install.
4) Is the P3BEHD3090 a standalone circuit breaker or does it need a busway?
It is a plug-in unit, not a loose breaker. The 90 amp E frame breaker comes already enclosed and fitted with the stabs to land on an Eaton Pow-R-Way III busway run. There is nothing to mount it to on a wall as a disconnect, and it will not fit a panelboard interior. If you want an enclosed 90 amp breaker fed by conduit, you are looking for a separate enclosed circuit breaker instead.
5) How big and heavy is the P3BEHD3090 plug-in unit, and can one person hang it?
The unit measures 21.2 by 12.36 by 5.43 inches and weighs 25 pounds. At that weight and size it is a two-hand lift overhead onto the busway plug-in opening, so plan on a lift or a second set of hands if the run is at ceiling height. The 5.43 inch depth is what determines your clearance off the face of the bus run.
6) What is the exact part number to order this 90 amp Pow-R-Way III plug-in unit?
Order it as P3BEHD3090 from B-Line. That number encodes the Pow-R-Way III plug-in unit with an E frame breaker at 90 amps. Adjacent catalog numbers in the same series change the amp rating or the ground configuration, so the digits matter when you are matching an existing drop on a run.
