Blackburn FBXD24-1 FLEX BRAID 105,600 KCMIL 24 IN

24 inches overall. That length is what suits a hinged switchgear or enclosure door, a long expansion span on a bus run, or a bond across a piece of equipment sitting on vibration isolators where the two landing points are far apart. If your two pads are close together, a 24 inch braid will need to be looped and secured so it does not chafe on an edge or foul a moving part.

It carries UL E3060 and CSA LR29625. That covers you on both sides of the border for an inspected job, so it can be specified on utility, industrial, and institutional work where a listed bonding jumper is called for on the drawing.

One hole per end. A single-hole pad lands on a stud or a single tapped hole, which is the common arrangement on enclosure doors, motor frames, and equipment ground pads. Where the connection carries real fault current or sits on a bus bar, a two-hole pad is usually specified instead because it resists rotation and keeps the joint from loosening under vibration. Check what the pad you are landing on is drilled for before you order.

The FBXD24-1 is a flat, flexible tin-plated copper braid jumper with a one-hole terminal pad on each end. It bonds two points that need to stay electrically connected while one of them moves, vibrates, or expands: switchgear doors, transformer cases, generator skids, bus expansion joints, and equipment grounding across isolation pads. The braid construction lets it flex repeatedly where a solid conductor or a stiff cable lug would fatigue.

The conductor is tin-plated copper. The tin coating slows oxidation on the strand surfaces and at the terminal pads, which is what you want in a damp vault, a wash-down area, an outdoor pad-mount enclosure, or anywhere the braid is exposed. Bare copper braid greens up and the contact resistance at the bolted joint climbs over time. Still use an antioxidant compound on the mating surfaces and torque the bolt to the equipment maker's value.

Flat braid takes the bend in one plane and distributes the flexing across many fine strands, so it survives repeated door swings and vibration better than a round cable with crimped lugs. It also lies tight against a panel or frame instead of standing proud. The FBXD24-1 is a flat flexible conductor with the pads formed as part of the assembly, so there is no field crimping and nothing to get wrong on the connection. Round flexible cable is the better pick where the bond has to twist in more than one axis or route through conduit.

Country of origin is the United States, which is what a government, utility, or federally funded project needs on record when domestic sourcing is written into the spec. Pair that with the UL E3060 and CSA LR29625 listings and it covers most institutional submittal requirements for a bonding jumper.

Blackburn FBXD24-1. The FBXD prefix is the flexible braid expansion connector series, 24 is the length in inches, and the -1 is the single-hole pad configuration. Quote that full string, since the same series runs in other lengths and hole counts and a partial number will get you the wrong span.

Sold each. So if you are bonding a run of enclosure doors or a bank of isolated equipment, count the openings and order that quantity; there is no minimum bundle to work around.
