B-LINE P3BFDC3070N – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BFDC3070N plug-in unit use?
The P3BFDC3070N is a 70 amp plug-in unit built on an F frame breaker, which covers the 15 to 225 amp range. If your feeder tap calls for a different amp rating within that band, you stay in the same F frame family; a larger load moves you off F frame entirely.
2) Will a 70A Pow-R-Way III plug-in unit hold up on a 480V busway run?
Yes. The interrupting rating on this unit is 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac, so it covers standard 480Y/277 distribution as well as 600V systems. Check the available fault current at the tap point against the rating for your system voltage before you commit.
3) Does this Pow-R-Way III plug-in unit have a full neutral, and what ground does it come with?
Neutral is rated 100 percent, so it suits panel and receptacle loads where the neutral carries full current, including nonlinear loads on a 4 wire run. Grounding is 50 percent integral housing ground rather than a full size insulated ground conductor. If your spec sheet calls for a 100 percent or isolated equipment ground, this configuration will not satisfy it.
4) How big and how heavy is the B-Line P3BFDC3070N plug-in unit for planning the lift and clearance?
It measures 21.2 inches high, 12.36 inches long, 5.43 inches wide, and weighs 25 pounds. That is a two-hand lift onto the busway at height, and the 21.2 inch dimension is what governs your vertical clearance where units stack along the run.
5) Is a plug-in breaker unit the right way to tap a busway, or should I run a separate panel?
A plug-in unit like the P3BFDC3070N is the standard way to take a protected tap directly off a Pow-R-Way III busway run, which is why it is used over conduit and a remote panel in warehouses, plants, and data halls where load locations move. The unit contains the F frame breaker itself, so the tap is protected at the busway rather than back at a distribution board. If you need many small circuits at one point instead of one 70 amp feed, a panelboard fed from the tap is the better arrangement.
6) What exact part number should I order to match an existing 70 amp Pow-R-Way III tap?
Order by manufacturer part number P3BFDC3070N. That number carries the 70 amp rating, F frame breaker, 100 percent neutral, and 50 percent integral housing ground. Units in this family differ only by a few characters, so matching the full string is how you avoid getting a different neutral or ground configuration on the same amp rating.
