B-LINE P3BEHD3080N – Frequently Asked Questions
1) What amperage and interrupting rating does the B-Line P3BEHD3080N plug-in unit carry?
The P3BEHD3080N is an 80 amp plug-in bus plug built around an E Frame breaker (the E Frame covers 15 to 225 A). Interrupting capacity is 18 kAIC at 240 Vac and 14 kAIC at 480 Vac, so check your available fault current at the tap point against those two numbers before you specify it.
2) Can I use this bus plug on a 480 volt busway run?
Yes, it is rated for use at 480 Vac, but with a lower interrupting capacity there: 14 kAIC at 480 Vac versus 18 kAIC at 240 Vac. On a 480/277 V system, compare 14 kAIC against the calculated fault current at that point on the busway. If the available fault current exceeds it, this plug is not the right selection.
3) Does the P3BEHD3080N include a neutral, and what ground does it provide?
It is configured with a 100% rated neutral and a 50% integral/housing ground. That means you can land a full-capacity neutral for line-to-neutral loads such as 277 V lighting or receptacle panels, and the equipment ground path is through the unit housing at 50% capacity rather than a separate full-size ground bar.
4) How much does an 80A Pow-R-Way III bus plug weigh, and can one person hang it?
Plan on 25 pounds. At that weight plus the reach, most crews stab these two-handed off a lift with a second person steadying the unit. It is not a one-hand overhead install.
5) What are the dimensions of the P3BEHD3080N plug-in unit for clearance planning?
The unit measures 21.2 x 12.36 x 5.43 inches (height, length, width as listed). Use the 21.2 inch height when checking drop clearance below the busway and the 5.43 inch width when spacing adjacent plugs along the run.
6) Is a bus plug like this the right way to feed a panel, or should I run conduit from the switchboard?
A plug-in unit like the 80A P3BEHD3080N is the right call when you already have Pow-R-Way III busway overhead and want a tap you can add, move, or re-rate later without pulling new feeders. It gives you an 80 amp breaker-protected tap right at the load. If there is no busway in the space, a bus plug does nothing for you and a conduit-and-wire feeder from the distribution gear is the only option. Busway taps pay off in plants, data halls, and light industrial bays where loads get relocated.
7) What exact part number should I put on the purchase order for this 80 amp Pow-R-Way III plug?
Order by Eaton/B-Line part number P3BEHD3080N. That single number carries the 80 amp rating, the E Frame breaker, the 100% neutral, and the 50% integral housing ground, so there are no separate option suffixes to add.
8) Is the breaker inside this unit replaceable or re-ratable to a different amperage?
The P3BEHD3080N is built with an E Frame breaker, a frame that spans 15 to 225 A. The unit itself is factory-configured at 80 amps, so if your load changes you order the plug in the amperage you need rather than treating this one as field-adjustable.
