Blackburn EXB150A1304 EXTRA FLEX BRAID 2H NEMA 12IN LONG

It's a flat, extra flexible tin-plated copper braid jumper with a two-hole NEMA pad on each end, 12 inches long. Braid jumpers like this bond equipment that moves or vibrates, across expansion joints, on transformer cases, switchgear doors, generator skids, or busway sections, where a rigid conductor or a solid bar would fatigue and crack. The flat braid construction flexes repeatedly without work-hardening the way a solid conductor would.

Yes, the EXB150A1304 is a two-hole braid connector with NEMA-pattern pads, so it bolts to standard two-hole NEMA ground pads at each end rather than relying on a single bolt. Two-hole termination is what keeps a bonding jumper from rotating loose under vibration, which is the whole reason you'd use a braid jumper on moving or vibrating equipment.

The conductor is tin-plated copper. The tin plating slows oxidation on the strands, which matters on braid more than on solid conductor because a braid has enormous surface area and any corrosion product between strands drives up resistance. Tinned braid is the usual choice for damp locations, outdoor pads, and anywhere the jumper sees salt or industrial atmosphere.

Not where the connection moves. Stranded cable handles occasional flex, but on equipment that vibrates continuously or joints that cycle open and closed, the strands fatigue and break inside the lug. An extra flexible flat braid is built for that duty, and this one is classified as a very flexible conductor for exactly that reason. For a static bond between two fixed pads, a stranded jumper or a solid bonding bar is the simpler pick.

Sold each, one braid jumper per unit. If you're bonding a run of busway sections or a bank of enclosure doors, count the joints and order one per joint. Bolts and washers for the NEMA pads are not part of the braid itself, so plan on hardware sized to your ground pad pattern.

Blackburn EXB150A1304. That's the manufacturer part number to quote, and it identifies the 12 inch, two-hole NEMA, extra flexible braid configuration. Made in the United States.

If your specification carries a domestic-content requirement, the EXB150A1304 braid is manufactured in the United States, which is the data point a submittal reviewer usually wants on grounding accessories. Pair it with the manufacturer part number on your submittal so the reviewer can match it to the spec line.
