Blackburn FBE4H340A1-23 – Frequently Asked Questions
1) How long is the Blackburn FBE4H340A1-23 jumper braid?
The FBE4H340A1-23 braid assembly measures 23.5 inches (596.9 mm) overall. That length is the deciding factor on most jobs: it needs to reach between the two bonding points with enough slack that the braid stays flexible and isn't pulled taut across a hinge, expansion joint, or vibrating equipment mount.
2) What is a flexible jumper braid used for versus a solid bonding conductor?
An extra-flexible braid like the Blackburn FBE4H340A1-23 is used where the two bonded points move relative to each other: equipment on vibration isolators, hinged enclosure doors, busway and raceway expansion fittings, transformer and motor frames. Solid or stranded bonding conductor is fine for static connections, but it work-hardens and eventually cracks under repeated flexing. That's the whole reason the braid exists.
3) Does the Blackburn FBE4H340A1-23 come as a complete assembly with terminals, or just braid?
It ships as a made-up assembly, not cut bulk braid, and it's sold each, so one order gets you one finished jumper ready to bolt in. Nothing has to be crimped or cut on site.
4) Does the Blackburn FBE4H340A1-23 jumper meet a recognized standard?
The braid assembly is built to NEMA. For a specifier or MRO buyer standardizing bonding jumpers across a facility, that's the standard referenced on this part.
5) Is the Blackburn FBE4H340A1-23 made in the USA?
Yes, country of origin is the United States. That matters on government, institutional, and federally funded work where domestic-origin electrical material is a condition of the contract.
6) How many of these bonding jumpers do I get per order?
One. The FBE4H340A1-23 is sold individually, each, so if you're bonding a run of enclosure doors or a bank of isolated equipment, order one per connection point.
