Blackburn FBE36-1 FLEXIBLE BRAID 168 KCM, 36INCH LONG

The FBE36-1 is an extra flexible tin-plated copper braid bonding jumper, 168 KCM, 36 inches long, with a one-hole terminal for bolting to a grounding pad or lug. Flat flexible braid is used where the bond has to tolerate movement or vibration, so it is the common choice for bonding across expansion joints, transformer and switchgear enclosures, motor frames, and equipment that shifts relative to the structure. It ships as a single piece, sold each.

One-hole. The FBE36-1 is a 1-hole extra flexible braid connector, so it lands on a single bolt at each end. If your spec or drawing calls for a two-hole NEMA pad connection, typically required to keep a heavy bonding conductor from rotating on the pad, this is not the part for that detail and you need the two-hole version of the braid.

It carries UL E3060 and CSA LR29625. That matters on inspected work, where a bonding jumper on a service, a generator, or a piece of listed equipment is expected to be a listed connector rather than a fabricated strap. The braid is also made in the United States, which covers Buy American language on federal and many institutional jobs.

Flat braid flexes in every direction and absorbs movement without loading the terminals. A solid bar bonds fine but transmits any relative movement straight into the bolted joints, so it belongs where both ends are rigid to each other. Stranded cable flexes but has more bending stiffness and takes up more room than flat braid in a tight enclosure or across a narrow expansion gap. The FBE36-1 is the braid option: flat, extra flexible, tin-plated copper.

The cable length is 36 inches. Order by the run you need plus enough slack for the movement the joint will see, since a braid pulled tight defeats the reason for using braid. Blackburn builds the FBE series in other lengths, so if 36 inches is longer or shorter than your gap, look for the same FBE 1-hole braid in the length you need rather than cutting this one.

Tin plating over the copper is there for exactly that reason. It slows oxidation of the copper surface and reduces the galvanic activity you get when bare copper is bolted against aluminum or galvanized steel, which is why tinned bonding hardware is normally specified for outdoor, damp, and mixed-metal connections. Clean the mating pad and use the antioxidant the equipment manufacturer calls for.

The braid is sold as a single item, each, with the 1-hole terminals formed on it. Bolts, nuts, washers, and any antioxidant compound are separate, so pick up hardware sized to the pad you are landing on and to the terminal hole when you order the braid.

Order Blackburn FBE36-1. That is the manufacturer part number for the 168 KCM, 36 inch, 1-hole extra flexible braid. The FBE prefix identifies the flexible braid family, and the suffix after the length indicates the one-hole configuration, so do not confuse it with the two-hole variant when matching a bill of material.
