Blackburn EXA100A1304 – Frequently Asked Questions
1) What is the Blackburn EXA100A1304 flexible braid connector used for?
It's a flexible braided jumper for high-current connections, rated 1000A, built from tin-plated copper braid with a flat conductor shape and a single-hole terminal pad on each end. The braid lets it absorb vibration, thermal expansion, and slight misalignment between two bolted bus or equipment terminals, which a rigid bar cannot do. It is made to IEEE/ANSI C37.34, the standard covering flexible connectors for switchgear applications.
2) How long is the EXA100A1304 braid connector?
The braid is 12 inches long, which corresponds to the 304MM in the part designation. That is the overall connector length you have to work with, so measure the gap between your two terminal pads plus the slack you want for movement before committing to this one.
3) Is this Blackburn braid a one-hole or two-hole connector?
One-hole. Each pad takes a single bolt, so it lands on equipment terminals drilled for one fastener. If your bus pad is drilled two-hole on NEMA centers, this braid will not line up and you want the two-hole version of the EX-FLEX braid instead.
4) Why tin-plated copper instead of bare copper braid?
The conductor is tin-plated copper. The plating slows oxidation on the braid strands and on the bolted contact face, which keeps joint resistance stable over time and makes it a safer match against aluminum or plated bus hardware than bare copper would be.
5) Does the EXA100A1304 meet a recognized switchgear standard?
It is built to IEEE/ANSI C37.34, the standard for flexible high-current connectors used with switchgear. If your spec calls out C37.34 for flexible connections, this braid answers it.
6) Can I use a rigid copper bar instead of this flexible braid?
Only where nothing moves. A solid bar transfers vibration and thermal growth straight into the terminal and the bolts. Where a breaker rolls in and out, where a transformer or generator vibrates, or where two sections expand independently, you want the flexible flat braid so the joint takes the movement instead of the hardware.
7) What is the exact Blackburn part number to order for the 1000A 12-inch braid?
EXA100A1304 is the manufacturer part number for the 1000A, one-hole, 304 mm tin-plated copper EX-FLEX braid. Use that full string when cross-referencing, since the length and hole count are both encoded in it.
8) Is the EXA100A1304 sold individually or in a pack?
Sold each. A single braid covers one connection, so for a three-phase run you order three, and add a fourth if you are jumping a neutral as well.
9) Where is the Blackburn EX-FLEX braid made?
Country of origin is the United States, which matters if you're buying against a Buy American or domestic-content requirement on a government or utility job.
