B-LINE P3BJDC3070G – Frequently Asked Questions
1) What interrupting rating does the 70A JDC frame plug-in unit have at 480V?
100 kAIC at 480 Vac. The same unit is rated 200 kAIC at 240 Vac and 35 kAIC at 600 Vac. Check the available fault current at the tap point against the voltage you are actually running, since the rating drops sharply as system voltage rises.
2) Can I use this 70A unit on a 600 volt busway system?
It can be applied at 600 Vac, but the interrupting rating there falls to 35 kAIC, against 100 kAIC at 480 Vac. On a 600V run with high available fault current, run the short-circuit study first; 35 kAIC is the limiting number, not the 200 kAIC figure quoted at 240V.
3) What does the JDC frame designation mean for this 70 amp busway plug?
JDC refers to the J frame breaker inside the plug-in unit, set at a 70 amp rating. The frame size governs the physical breaker and its interrupting capability, while 70A is the trip rating. If your drawing calls out a different frame letter at 70A, the enclosure and interrupting ratings will not match this unit.
4) How much clearance and lifting help do I need to install this busway breaker plug?
Plan for a unit measuring 23.26 x 12.36 x 6.97 inches that weighs 47 lb. At that weight, overhead installation on a busway run is a two-person job or one that wants a lift, and you need enough working clearance around the plug-in opening for the full 23.26 inch dimension plus the operating handle access.
5) Does this Pow-R-Way III plug-in unit meet NEMA requirements for a spec job?
The unit is NEMA compliant and IEEE certified. Those are the two designations carried on the P3BJDC3070G, which covers most institutional and industrial busway specifications calling for NEMA-compliant tap-off devices.
6) Should I use a circuit breaker plug-in unit or a fusible switch tap on a busway run?
A breaker plug-in unit like the 70A JDC unit gives you a resettable device, so after a fault or overload the maintenance crew resets the handle instead of stocking and swapping fuse elements. A fusible tap needs replacement fuses on hand and matched sizing every time. Where you need very high interrupting capacity at 240V, note this breaker unit is already rated 200 kAIC at that voltage, so a fusible tap is not required to get there.
7) What is the exact part number to order for a 70 amp 3-pole Pow-R-Way III breaker plug with 50% ground?
Order B-Line P3BJDC3070G. That single part number covers the 3-pole, 70 amp, JDC frame plug-in unit with the 50% internal ground; there are no separate finish or configuration choices to specify on it.
