Blackburn EXB070A1304 EX-FLEX BRAID TNCU 700A 2H 304MM

It's a flat, extra-flexible tin-plated copper braid jumper with a two-hole terminal pad at each end, rated 700A. Braid jumpers like this bridge two bolted bus or equipment pads where movement, vibration, or thermal expansion would stress a rigid bar, typical on switchgear, transformer terminals, and disconnect connections. The braid construction lets the connection flex while carrying full current.

304 mm, which is 12 inches, measured as the cable length. That is the dimension to check against your pad-to-pad spacing: you want enough length for a relaxed loop so the braid absorbs movement rather than pulling on the bolted pads.

Two-hole pads on the EXB070A1304. A two-hole termination resists rotation under fault current and is what most utility and switchgear specs call for on bus connections, so you'll be drilling or matching a two-bolt pattern on each landing pad rather than a single stud.

Where the two pads move relative to each other, yes, and that is exactly what this braid is for. Rigid bar links are fine for fixed, aligned pads; they transmit vibration and thermal growth straight into the bolted joint. The extra-flexible flat braid takes that movement instead. Use the braid on breaker to bus connections, transformer terminals, and anywhere equipment is racked, shifted, or expands with load.

The braid is tin-plated copper. Tin plating slows oxidation on the strands and at the bolted pad interface, which matters for connections in humid, outdoor, or industrial atmospheres and when landing on aluminum or plated bus. Bare copper braid will darken and build oxide at the contact surface over time.

Made in the United States, which is the answer needed for Buy American and domestic-content sourcing on federal, utility, and institutional projects.
