Blackburn FBXD18-1 FLEXIBLE BRAID 105.6 KCMIL, 18 LONG

The FBXD18-1 is a flat flexible tin-plated copper braid jumper, 105.6 kcmil, 18 inches long, with a one-hole terminal pad on each end. It bonds two points that move or vibrate relative to each other, or that need an expansion allowance, where a solid or stranded conductor would work-harden and fail. Typical uses are bonding across equipment enclosure doors and hinged panels, across expansion joints in raceway or busway runs, and grounding jumpers on rotating or vibrating machinery.

It carries UL E3060 and CSA LR29625. That matters on inspected work, since bonding jumpers on a permanent installation generally have to be a listed component, and the CSA file covers you on Canadian jobs as well as US ones. The braid is also made in the United States, which is the answer an institutional or government buyer usually needs for domestic-preference purchasing.

Braid is the right choice anywhere the connection flexes. Stranded copper bends a limited number of times before individual strands break at the lug barrel; a flat braid of many fine tin-plated copper wires distributes that motion over its whole width and survives repeated cycles. The flat shape also gives more surface area for a given cross-section, which helps on high-frequency or fault-current bonding. For a fixed, non-moving bond, ordinary stranded conductor with compression lugs is cheaper and entirely adequate. The FBXD18-1 covers the moving case at 105.6 kcmil equivalent, 18 inches long.

Yes. The conductor is tin-plated copper rather than bare copper. The plating slows oxidation on the pad faces, which keeps contact resistance stable in humid, outdoor, or corrosive environments, and it is the plating normally specified when a copper connector lands on aluminum bus or an aluminum enclosure, since bare copper against aluminum is the galvanic pairing you want to avoid. Bare copper braid is fine indoors on copper-to-copper bonds.

The stated cable length is 18 inches, and the model designation itself carries the 18. That figure is the braid length; the one-hole terminal pads at each end are rigid and take up part of any run, so lay out your bolt centers with some slack rather than pulling the jumper taut. A braid installed straight and tight transmits the movement into the pads instead of absorbing it, which defeats the point of using braid.

No hardware is included with the braid itself. Each end is a one-hole pad, so you need one bolt, nut and washer set per end, sized to the pad hole and to the tapped hole or bus hole you are landing on, plus a Belleville washer where the spec calls for one on a bonding connection. Verify your bolt diameter against the pad before you go to site.

Individually. The selling unit of measure is each, and the orderable item is a single model, FBXD18-1. If you are bonding a row of enclosure doors or a series of expansion joints, count one jumper per connection point and order that quantity.
