Blackburn FBE4H250A1-20 – Frequently Asked Questions
1) How long is the Blackburn FBE4H250A1-20 jumper braid?
The FBE4H250A1-20 braid assembly is 20 inches long (508 mm). That length is what determines whether it will reach between your two bonding points with enough slack left for movement, so measure the run before you order.
2) Is the Blackburn FBE4H250A1-20 bonding braid insulated?
No. It is a non-insulated braid, so the conductor is bare along its length. If it will be routed where it could contact energized parts or a grounded surface you do not intend to bond, sleeve it or reroute it.
3) Why use a flexible braid instead of solid bonding wire across a moving connection?
An extra-flexible jumper braid like the Blackburn FBE4H250A1-20 is built for spots where the two bonded parts move relative to each other or vibrate, such as equipment doors, hinged panels, transformer connections, and expansion joints. Stranded or solid bonding conductors work harden and eventually crack at the flex point; a braid distributes the bending across many fine strands. For a fixed bond with no movement, a standard bonding jumper or grounding conductor is the simpler choice.
4) What standard does the Blackburn FBE4H250A1-20 braid conform to?
NEMA is the standard listed for this grounding assembly. Facility and MRO buyers specifying to a NEMA reference on a drawing can match it on that basis.
5) Is the Blackburn FBE4H250A1-20 sold individually or in a pack?
It is sold each, one braid assembly per unit, under manufacturer part number FBE4H250A1-20. If you are bonding multiple panel doors or enclosures, order one per connection point.
6) Is the Blackburn FBE4H250A1-20 made in the USA?
Country of origin is the United States. That matters for government, transit, and institutional jobs carrying domestic-content requirements on the bill of materials.
