Blackburn FBE24-1 FLEX BRAID 168KCMIL 24 INLG 1 HOLE

The FBE24-1 is a flat, extra-flexible tin-plated copper braid jumper with a one-hole terminal pad at each end, sized at 168 kcmil and 24 inches long. Braid jumpers like this bond across points that move or vibrate, or where a rigid conductor cannot be bent, such as switchgear doors, transformer and enclosure bonding, bus bar to bus bar jumpers, and equipment grounding on rotating or shifting apparatus. The flat braid construction flexes repeatedly without work-hardening the way a solid or stranded cable would.

Yes. The FBE24-1 carries UL file E3060 and CSA file LR29625, so it is acceptable on both US and Canadian installations where a listed bonding jumper is called for.

The braid is 24 inches long overall, measured as the cable length. The one-hole pads are pressed on each end, so plan your bolt-to-bolt run a little shorter than 24 inches and leave slack in the braid so the flex is not taken up in tension. If the gap between your two lugs is much less than that, order a shorter FBE length rather than folding this one back on itself.

Where the two ends never move, ordinary stranded cable with compression lugs is fine. Choose an extra-flexible flat braid instead when the connection has to move or vibrate: hinged switchgear or enclosure doors, generator and motor bonding, bus expansion joints, seismic gaps. The FBE24-1 is built for that duty, rated 168 kcmil with flat flexible construction that takes repeated movement without cracking strands or loosening the pad.

Country of origin on the FBE24-1 is the United States, which is what a government, transit, or federally funded project submittal usually needs to see on a bonding jumper.

Each end of the FBE24-1 has a single bolt hole in the pad, and the mounting bolt, nut, and washers are not supplied with the braid. Match the hardware to the hole in the pad and to the tapped bus or lug you are landing on, and use a flat and lock washer on each end so the joint stays tight under vibration.

On Blackburn's flexible braid line the number after FBE is the length in inches and the digit after the dash is the number of holes in the terminal pad. FBE24-1 is therefore a 24 inch braid with one-hole pads, at 168 kcmil. To order, you settle three things: braid ampacity or kcmil size, the length you need between landing points, and whether your bus prep takes a one-hole or two-hole pad.

The FBE24-1 conductor is tin-plated copper. The tin plating slows oxidation on the strand surface and at the pad face, which keeps contact resistance stable over time and makes it a better match for aluminum or plated bus and lugs than bare copper. It also holds up better in damp or industrial atmospheres.

It sells as each, one FBE24-1 braid jumper per unit. If you are bonding both leaves of a double door or doing several cubicles, count the jumpers you need and order that quantity.
