Blackburn FB2D36 FLEXIBLE BRAID 153.6KCMIL 36IN LONG

36 inches of cable length, and it ships as an each, one braid per order. If you are bonding several joints on the same gear, order one per joint.

It is a 153.6 KCMIL braid, so it is in the range of a 2/0 to 3/0 copper conductor by cross-section. Size your bonding jumper to the equipment ground or bonding requirement on your drawing and confirm the braid's rating matches before you substitute it for a cable jumper.

It carries UL file E3060 and CSA LR29625. That is the pairing an inspector or institutional spec usually wants to see on a bonding jumper, and it is worth noting for anyone working to both US and Canadian requirements on the same project.

The FB2D36 is a flat, flexible tin-plated copper braid jumper with a two-hole terminal at each end, used to bond across moving or vibrating joints, expansion points, hinged enclosure doors, switchgear bus, transformer cases and similar equipment where a rigid conductor would fatigue. The flat braid construction flexes repeatedly without work-hardening the way a solid bar would, and the two-hole pads bolt down so the connection cannot rotate loose under vibration.

Two-hole pads on each end mean you supply the bolts, nuts, flat and belleville or lock washers to match the drilling on your bus or equipment pad. No mounting hardware is included with the braid itself. Confirm the hole spacing and diameter on the pads against your existing bus drilling before you cut anything else on the job.

No. The FB2D36 is a factory assembly, 36 inches with a formed two-hole pad crimped at each end. Cutting it destroys one terminal and voids the UL E3060 listing that makes it acceptable as a bonding jumper. If 36 inches is too long, route the slack in a gentle loop, which is what the flexible braid is meant to do anyway, or order a shorter length in the FB2D series.

Use the flat flexible braid where the joint moves: expansion joints, vibration isolators, hinged doors, rolling or sliding equipment. Braid takes repeated flexing far better than a lug-and-cable jumper and its flat profile fits tight clearances between bus bars. A stranded cable jumper with compression lugs is the simpler choice for a static bond where nothing moves and nobody cares about profile. The FB2D36 is the moving-joint answer, at 36 inches and 153.6 KCMIL.

Order by the part number FB2D36. Within the FB2D family the digits after FB2D are the length in inches, so FB2D36 is the 36 inch version at 153.6 KCMIL with a two-hole pad on each end. If your drawing calls out a different length or a single-hole termination, that is a different catalogue number even though the braid looks identical.

The FB2D36 braid is tin-plated copper. The plating slows oxidation on the strand surface and on the terminal pads, which keeps contact resistance stable over time and reduces galvanic trouble where the braid bolts to aluminum or galvanized equipment. Bare copper works electrically but the pad surface dulls faster, particularly in damp or outdoor enclosures.

Country of origin is the United States, which matters if you are procuring for a government, federal or institutional job carrying domestic-content language.
