B-LINE P3BFDC3030G – Frequently Asked Questions
1) What is the interrupting rating on this 30 amp busway plug-in breaker at 480 volts?
Short circuit interrupting capacity runs 200 kAIC at 240 Vac, 100 kAIC at 480 Vac and 35 kAIC at 600 Vac. On a 480 Vac three-phase run that means 100 kAIC available fault current coverage, which is what an engineer will want to see against the calculated fault current at that point in the distribution.
2) Is the FDC frame breaker in this plug-in unit a 3-pole 30 amp, and what frame size is it?
Three-pole, 30 amp trip, on an F frame breaker (FDC frame type). The 3-pole configuration suits 3-phase loads; for a single-phase or 2-wire load you would specify a 2-pole unit instead.
3) Does the P3BFDC3030G include a ground path, or do I need a separate ground bus?
It is supplied with 50% internal ground, so the equipment ground path is integral to the unit and matches a Pow-R-Way III run ordered with 50% internal ground. If your busway was specified with a full-capacity ground or an external ground bar, order the matching grounding option instead so the plug-in and the run agree.
4) Can I use this 30 amp plug-in unit on a 600 volt busway run?
Yes, it is rated to 600 Vac, with 35 kAIC interrupting capacity at that voltage. Compare that 35 kAIC against the available fault current at the tap point on a 600 V system before committing, since the rating drops from 100 kAIC at 480 Vac.
5) How much does a B-Line busway plug-in breaker unit weigh, and can one electrician hang it?
The unit weighs 25 lb and measures 21.2 in high, 5.43 in wide and 12.36 in deep. At that weight and length it is a two-hand lift overhead on a ladder or lift, so most crews stage it with a second person or a hoist when plugging into an elevated busway run.
6) Does this busway breaker plug-in meet NEMA standards for a spec job?
The unit is NEMA compliant and IEEE certified, which is usually what a submittal package asks for on a busway tap. Those are the ratings carried on record for it, alongside the 200/100/35 kAIC interrupting ratings at 240, 480 and 600 Vac.
7) Should I use a plug-in breaker unit or a fusible switch unit to tap a busway run?
A circuit breaker plug-in like the P3BFDC3030G gives you a resettable device: after a trip you clear the fault and close the handle, with no fuse stock to keep. A fusible plug-in unit needs replacement fuses on hand and matched fuse classes, but is often chosen where very high interrupting capacity or specific coordination with fuse curves is required. This one already carries 200 kAIC at 240 Vac and 100 kAIC at 480 Vac, so fault capacity is rarely the reason to go fusible here.
8) What is the exact part number to order this 30 amp 3-pole B-Line busway plug-in?
Order B-Line part number P3BFDC3030G. That number covers the Pow-R-Way III plug-in unit with the FDC frame breaker, 3-pole, 30 amp, 50% internal ground. It is a single configuration, so there are no separate finish or voltage suffixes to add.
