B-LINE P3BFDC3030N – Frequently Asked Questions
1) Will a P3BFDC3030N plug-in unit fit any busway, or only Pow-R-Way III?
This is a Pow-R-Way III plug-in unit. It plugs into Pow-R-Way III busway run only, since the housing and stabs are built for that bus system. Other busway families use different plug-in openings and stab geometry, so a Pow-R-Way III unit is not the part for them.
2) What voltage and short circuit rating does the 30 amp FDC plug-in breaker unit carry?
Interrupting rating runs 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. That 480 Vac figure is the one that matters on most commercial 480Y/277 busway risers, and 100 kAIC covers service-entrance-adjacent taps where available fault current is high.
3) Does this bus plug include a neutral for 277V lighting or single-phase loads?
Yes, it is configured with a 100 percent rated neutral, so you can pull single-phase 277V lighting circuits or other line-to-neutral loads off it without derating the neutral. Grounding is 50 percent integral housing ground.
4) Is the 30A in P3BFDC3030N the breaker trip rating or the bus plug rating?
30A is the breaker rating inside the plug-in unit, a 3-pole 30 amp FDC frame device. So you get 30 amps of protected feeder out of the plug, regardless of the ampacity of the busway run it hangs on.
5) Do I need to run a separate equipment ground to the load from this plug-in unit?
The unit uses a 50 percent integral/housing ground, meaning the busway housing itself serves as the equipment grounding path back to the source. Whether you also pull a wire-type EGC to the downstream load is decided by the load circuit design and your local inspector, not by the plug.
6) How much does a Pow-R-Way III 30 amp bus plug weigh and how big is it, for rigging and clearance?
25 lb, measuring 21.2 in high, 5.43 in wide, and 12.36 in deep. One person can set it, but plan the depth: 12.36 in of projection off the busway plus room to swing the operating handle is what you need to keep clear of ductwork, pipe, or racking below the run.
7) What does the FDC frame designation mean when I am matching a replacement bus plug?
FDC is the circuit breaker frame type inside the unit, an F frame device. When you are matching an existing plug or standardizing spares across a facility, frame type plus pole count plus trip rating are the three things that have to agree: here that is F frame, 3-pole, 30 amp. A different frame in the same amperage is a different unit.
8) Is this bus plug suitable for a 600 volt busway system?
It is rated for use up to 600 Vac, with 35 kAIC interrupting at that level. Confirm the available fault current at the plug location is at or below 35 kA on a 600 V system; on 480 Vac the same unit gives you 100 kAIC of headroom.
9) What is the exact part number to order this 3-pole 30 amp Pow-R-Way III breaker plug?
Order B-Line part P3BFDC3030N. That number encodes the Pow-R-Way III plug-in unit with FDC frame breaker, 3-pole, 30 amp, 100 percent neutral.
10) Does this bus plug meet NEMA requirements for a spec that calls for standard busway devices?
The unit is NEMA compliant and IEEE certified. If your drawing calls out a NEMA busway plug-in device, that requirement is satisfied on the submittal.
