Blackburn EXH340A11400 – Frequently Asked Questions
1) What is the Blackburn EXH340A11400 flexible braid connector used for?
It's an extra flexible braid connector used to make a flexible current-carrying link between rigid bus or equipment terminals, so thermal expansion, vibration, and slight misalignment don't stress the bus. The conductor is a flat, very flexible tin-plated copper braid with four bolt holes per pad, and it's built to IEEE / ANSI C37, 34.
2) What current rating does the Blackburn EXH340A11400 carry?
It's a 3400 amp flexible connector, per the EXH340A11400 designation and description. That puts it in switchgear and substation bus territory rather than anything you'd find in a panelboard. Match the rating to the bus it bridges, not to the load.
3) How many bolts per end does this Blackburn flexible connector take?
Four holes per pad. Your bus or terminal pad has to have a matching 4-hole NEMA-style drilling, and you'll need to supply the bolts, nuts, and washers separately since the connector ships as a bare braid assembly.
4) Does the EXH340A11400 meet switchgear standards for substation work?
Yes. It's built to IEEE / ANSI C37, 34, the standards family covering high-voltage air switches and associated connection hardware, which is what utility and institutional specs for substation bus links normally call out.
5) Should I use a flexible braid connector or a solid bus link between two bus sections?
Use the flexible braid where the joint has to move: thermal growth on long bus runs, vibration from transformers or breakers, seismic separation, or equipment that gets removed and reinstalled. A solid bar link is fine only when both ends are fixed and aligned. The EXH340A11400 is the very flexible, flat-braid version, so it absorbs movement in more than one axis while still carrying 3400 amps.
6) Why tin-plated copper instead of bare copper braid on a bus connection?
The braid on this connector is tin-plated copper. The tin plating slows oxidation on the braid and the pad faces, which keeps contact resistance stable over time on a bolted joint. Tin pads also mate normally with tin-plated bus. If your existing bus is silver-plated, clean and torque to your standard practice for dissimilar plating.
7) Is the Blackburn EXH340A11400 sold individually or in a pack?
Sold each, one connector per order, and it is made in the United States. Order one per joint you're bridging.
