B-LINE P3BJDC3090N – Frequently Asked Questions
1) Will a Pow-R-Way III plug-in breaker unit fit any brand of busway?
No. The P3BJDC3090N plug-in unit is built for B-Line Pow-R-Way III busway and plugs onto that busway's plug-in openings. It is not a panelboard breaker and it is not a universal bus plug, so if your run is another manufacturer's busway you need that manufacturer's matching plug-in unit instead.
2) What short circuit interrupting rating does the 90A JDC bus plug have at 480V?
100 kAIC at 480 Vac. The same unit is rated 200 kAIC at 240 Vac and 35 kAIC at 600 Vac, so it covers a 480Y/277 distribution run with a high available fault current without needing a series-rated arrangement upstream. Check the value against the fault current at the plug-in location on your coordination study before you commit.
3) Is this a 3-pole 90 amp unit, and what breaker frame is inside it?
Three poles, 90 amps, on a J frame breaker (JDC frame type). That makes it a fit for a 3-phase load up to 90A continuous, and the J frame is what you reference when you're sourcing a replacement breaker or trip unit for the enclosure.
4) Does this bus plug give me a full neutral for 277V single-phase loads?
Yes, it's configured with a 100% neutral, so the neutral is rated for the full 90A of the phase conductors. That matters if you're feeding line-to-neutral loads such as 277V lighting or nonlinear loads where neutral current does not cancel. Grounding is 50% integral/housing ground.
5) How heavy is a 90A Pow-R-Way III bus plug, and can one person hang it?
It weighs 47 lb and measures 23.26 in high, 6.97 in wide and 12.36 in deep. That's a two-person lift when you're working off a lift or ladder at busway height, and worth planning hoisting or a plug-in hanger for on an overhead run.
6) Do I have clearance for a bus plug this size along my busway run?
Plan for a body 23.26 in in the long dimension, 6.97 in wide and 12.36 in deep hanging off the busway, plus room to operate the breaker handle and to pull conductors out of the bottom. On tight runs the 6.97 in width is what decides how closely you can space adjacent plugs.
7) Can I use this on a 600 volt busway system?
Yes, it carries a 600 Vac rating with 35 kAIC interrupting at that voltage. The interrupting capacity drops as system voltage rises (100 kAIC at 480 Vac, 200 kAIC at 240 Vac), so on a 600V system confirm available fault current is at or below 35 kA at that tap point.
8) What exact part number do I order for a 90A 3-pole Pow-R-Way III plug-in breaker with 100% neutral?
B-Line part number P3BJDC3090N. That single number covers the 3-pole, 90A, JDC frame plug-in unit with the 100% neutral and 50% integral/housing ground, so there are no separate options to call out when you order it.
9) Is this bus plug NEMA compliant for a spec job?
It's listed as NEMA compliant and IEEE certified. Those are the ratings on record for the P3BJDC3090N, and they're the ones to carry onto a submittal for a Pow-R-Way III plug-in unit.
