Blackburn FBG36-1 FLEX BRAID 600A 36 IN

The FBG36-1 is a flat, flexible tin-plated copper braid used as a bonding jumper in grounding and bonding work, rated 600A and 36 inches long. Typical use is bridging two points that need to stay electrically bonded while one of them moves or vibrates, such as across a transformer enclosure, switchgear door, expansion joint, or equipment mounted on isolators, where a solid conductor would fatigue and break.

One hole per end. The FBG36-1 is a 1-hole flexible braid, so each terminal end takes a single bolt or stud through the pad. Plan for a drilled and tapped hole or a through-bolt with hardware at both landing points; mounting hardware is not part of the braid itself.

Yes. The FBG36-1 is UL Listed and CSA Certified, which is what inspectors and institutional specs normally require for a grounding and bonding jumper. It is also made in the United States, which matters if you are working to a domestic-content requirement on a government or institutional job.

The FBG36-1 measures 36 inches overall, which is a long jumper by braid standards and is generally chosen where the two bonded points are well separated or where one end moves through a real range of travel, such as a hinged enclosure door, a swinging gate, or seismic and thermal expansion joints. For a short bond across a flange or a few inches of conduit, a 36 inch braid leaves excess that has to be routed and supported so it does not chafe or become a snag hazard; a shorter braid from the same flexible braid family is the better pick there.

Flexibility is the reason. A braid built from many fine tin-plated copper wires in a flat profile takes repeated flexing and vibration without work-hardening and cracking the way a stranded or solid cable lug assembly does. It also lies close to the surface, so it fits behind panels and under covers where a round cable with a bend radius would not. Where nothing moves and nothing vibrates, a conventional bonding conductor is simpler to terminate.

Order Blackburn FBG36-1. That is the manufacturer part number for the 600A, 36 inch, 1-hole flat flexible bonding braid in tin-plated copper.

It helps. The conductor is tin-plated copper, and the plating slows oxidation of the copper strands and of the contact face at the bolted connection, which is where resistance creeps up over time. That makes it a reasonable choice for outdoor enclosures, wet process areas, and dissimilar-metal landings where a bare copper braid would discolor and lose contact quality faster.

Sold each. The FBG36-1 is a single 36 inch braid per unit, so if a run needs a jumper at both ends of a moving joint you are ordering two.
