B-LINE P3BFDC3020N – Frequently Asked Questions
1) Will a P3BFDC3020N plug-in unit work on any busway, or only Pow-R-Way III?
The P3BFDC3020N is a Pow-R-Way III plug-in unit, so it lands on Pow-R-Way III busway runs only. Plug-in units are matched to the busway housing and stab arrangement of their own system, and this one is built for Pow-R-Way III. If your overhead run is a different busway system or generation, the unit will not seat on it.
2) What voltage can I use this 20A FDC plug-in breaker at, and what fault current does it interrupt?
Interrupting ratings on the 20 amp FDC unit are 200 kAIC at 240 Vac, 100 kAIC at 480 Vac and 35 kAIC at 600 Vac, so it is rated for service up to 600 Vac. Check the available fault current at the plug-in location against the figure for your system voltage; a 480 volt plant with under 100 kA available is well inside the rating.
3) Does the 100% neutral option matter for feeding lighting or receptacle panels?
It does. The P3BFDC3020N is built with a 100% rated neutral, which is what you want feeding lighting, receptacle and other single-phase or harmonic-heavy loads off a three-phase tap, because the neutral carries full phase current rather than a reduced share. The unit also carries 50% integral/housing grounding, so the busway housing serves as the ground path at half rating.
4) I need to replace one 20A plug-in unit on an existing Pow-R-Way III run. What do I have to match?
Match four things off the old unit's nameplate: the Pow-R-Way III busway system, the 3-pole configuration, the FDC (F frame) breaker, and the 20 amp trip. Also confirm the neutral and ground arrangement, because this one is 100% neutral with 50% integral/housing grounding, and a run built with a different neutral rating uses a different unit. If all four match, the P3BFDC3020N is a direct in-kind replacement.
5) Is this a 3-pole or 3-phase 4-wire tap, and how many loads can it feed?
Three poles, one breaker. The unit is a single 3-pole 20 amp circuit breaker plug-in, so it feeds one three-phase branch circuit (plus the 100% neutral where a neutral is needed). If you need several branch circuits off one bus opening, you want a panelboard or fusible switch plug-in unit rather than a single-breaker tap.
6) What does FDC frame type mean when I'm ordering a busway plug-in breaker?
FDC is the breaker frame designation inside the plug-in unit, catalogued as F frame. The frame sets the physical breaker size and the interrupting class, and the trip rating within it is what you pick, in this case 20 amps. Two plug-in units with the same amperage but different frames are not the same device, so match the frame letter on the drawing or the unit you are replacing.
7) Will this busway breaker unit satisfy a spec calling for NEMA compliant plug-in units?
The unit is NEMA compliant and IEEE certified. Those are the two designations carried on the record for this 20 amp FDC plug-in, so a specification written to NEMA busway requirements is met. Any additional listing your facility or inspector requires should be confirmed against the project specification.
