Blackburn FBC24-1 FLEXIBLE BRAID 48 KCMIL, 24IN LONG

The FBC24-1 is a flexible tin-plated copper braid bonding jumper, 24 inches long, with a single bolt hole at each termination. Flat flexible braid like this is used where two bonded points move relative to each other or need vibration isolation: transformer cabinets, switchgear doors, generator skids, hinged enclosure panels, and equipment grounding across expansion joints. The flat shape lays flat under a lug pad instead of standing off the way round cable does.

Yes. It carries UL file E3060 and CSA file LR29625, so it is recognized for both US and Canadian installations. That is the documentation an inspector or a spec reviewer typically wants on a grounding and bonding jumper.

The braid is rated 48 KCMIL of copper cross-section. Compare that figure against the conductor size your bonding or equipment grounding schedule calls for rather than eyeballing the braid width, since the woven strands make a braid look larger than its actual copper area.

It is a 1-hole braid, so each end lands on a single bolt. One-hole terminations are quicker to install and work on narrow pads or small bus tabs, but they allow the jumper to rotate around the bolt. Where rotation is a problem, or where the connection carries higher fault current on a wide pad, a 2-hole braid is the better choice.

The conductor is tin-plated copper. The tin plating resists oxidation and galvanic corrosion, which matters when the braid bolts to galvanized steel enclosures, aluminum bus, or sits outdoors and in damp mechanical rooms. Bare copper braid will darken and build oxide at the termination over time in those conditions.

The cataloged cable length is 24 inches. Measure the travel your equipment actually needs, door swing, skid movement, or expansion joint range, and leave slack so the braid flexes rather than pulls against the bolts. Blackburn builds the FBC series in a range of lengths, so if 24 inches leaves too much loop, a shorter braid in the same family is the cleaner install.

Use the braid where the connection moves. A stranded grounding conductor with crimp lugs is fine for a static bond between fixed steel, and it is usually easier to route in a raceway. A flat flexible braid is the right call across a hinge, on vibrating machinery, or over an expansion joint, because the woven flat conductor absorbs repeated flexing without work-hardening a solid lug barrel. The FBC24-1 is the flexible flat-braid version at 48 KCMIL, 24 inches.

No hardware is included. The FBC24-1 is sold as the braid itself, one per order, with a single hole at each end. Supply your own bolt, nut, lock washer, and any anti-oxidant compound to suit the pad you are landing on and the size of the existing hole.

Country of origin is the United States, which is what Buy American and domestic-preference procurement on federal, municipal, and institutional projects normally asks you to document.

The part number is FBC24-1: FBC for the flexible braid connector series, 24 for the 24 inch length, and the -1 for the one-hole termination. Ordering is by the each. If you need a different length or a two-hole end, the change shows up in those two positions of the number, so quote the full designation to your distributor rather than just the series.
