B-LINE P3BHJD3090GN – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BHJD3090GN plug-in unit use?
The P3BHJD3090GN is a 90 amp plug-in unit built around a J frame breaker, and the J frame covers 70 to 225 A. If your tap load calls for something under 70 A or above 225 A, you are outside this frame and need a different unit in the Pow-R-Way III plug-in line.
2) Is the interrupting rating on this Pow-R-Way III plug-in unit high enough for a 480V distribution busway?
At 480 Vac the unit is rated 65 kAIC. It is 100 kAIC at 240 Vac and 25 kAIC at 600 Vac. Compare those against the available fault current your engineer calculated at the busway tap point; if the study shows more than 65 kA at 480 V, this unit is not the right selection.
3) Does the P3BHJD3090GN plug-in unit include a full-size neutral and a ground?
Yes on both counts. The unit carries a 100 percent neutral and a 50 percent internal ground. The full-rated neutral matters on 3-phase 4-wire feeders serving nonlinear loads like LED drivers and VFDs, where neutral current can run high. The ground is internal to the unit, so no separate external ground bar assembly is being supplied.
4) Will this B-Line plug-in unit fit any manufacturer's busway?
No. The P3BHJD3090GN is an Eaton Pow-R-Way III plug-in unit, and the plug-in stabs and hanging hardware are specific to that busway system. It will not land on Square D I-Line, GE Spectra or Siemens bus. Confirm the nameplate on your existing run reads Pow-R-Way III before ordering.
5) How much does the B-Line P3BHJD3090GN weigh and can one electrician hang it alone?
It weighs 47 lb, which is a two-man lift or a mechanical hoist once you are working off a lift at busway height. Plan the plug-in installation accordingly, especially on overhead runs where the installer is handling the unit at arm's length.
6) What are the dimensions of the P3BHJD3090GN busway plug-in unit?
It measures 23.26 x 12.36 x 6.97 inches (height, length, width as published). Use the 23.26 inch height to check your clearance below the busway run and the 6.97 inch width against the spacing between adjacent plug-in openings, since back to back units on a tight bus can crowd each other.
7) I need to tap a busway for a 90 amp feeder to a panel. Is a circuit breaker plug-in unit the right choice over a fusible switch plug?
A breaker plug-in unit like this one gives you a resettable overcurrent device at the tap, which is what most facility maintenance groups prefer because there are no fuses to stock or replace after a fault. A fusible plug is the alternative where the spec calls for fuse coordination or a higher interrupting capacity than the breaker offers. This unit is a 90 A J frame breaker plug with 65 kAIC at 480 Vac, which covers most commercial 480 V distribution taps.
8) Can I use the P3BHJD3090GN on a 600 volt system?
It carries a 600 Vac rating, but the interrupting capacity drops to 25 kAIC at that voltage compared with 65 kAIC at 480 Vac. On 600 V systems with meaningful available fault current, run the numbers before you commit; the derated interrupting capacity is what rules this unit in or out.
9) What is the exact part number to order this Eaton Pow-R-Way III 90A plug-in unit?
Order it as P3BHJD3090GN. That single catalog number carries the 90 A rating, the J frame breaker, the 100 percent neutral and the 50 percent internal ground, so there are no separate suffixes to specify for those options.
