Blackburn STB040A1508 – Frequently Asked Questions
1) What is the Blackburn STB040A1508 flexible braid connector rated for, and where is it used?
The STB040A1508 is a 400 amp flexible braid connector with two bolt holes per pad, built for substation and switchgear work where a flexible shunt is needed between rigid bus or equipment terminals. It is made to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connectors. The braid is tin-plated copper, flat in shape, and it is sold each.
2) Is the Blackburn STB040A1508 a two-hole NEMA pad connector on both ends?
Yes, it is a 2-hole terminal braid, so each pad bolts down with two fasteners rather than one. Two-hole pads resist rotation under fault current and are what most switchgear and substation terminal preps are drilled for. Bolts, washers, and joint compound are not part of the connector itself, so order hardware separately.
3) Why use a flexible braid connector instead of a solid copper bus bar between two terminals?
A braid absorbs movement. Bolted rigid bus transmits thermal expansion, vibration, and switch operating motion straight into the terminal pads. The STB040A1508 is a flexible flat braid, so it carries the 400 amp connection while letting the two ends move relative to each other. Where nothing moves and the run is short, a rigid bar is the simpler choice.
4) Does the tin plating on this Blackburn braid matter for connecting to aluminum bus?
It does. The conductor is tin-plated copper, and tin plating is the usual specification when the braid lands on aluminum pads or sits in a damp or corrosive outdoor substation environment, because it limits the galvanic action and oxidation you get from bare copper against aluminum. Still use the joint compound and torque your equipment manufacturer calls for.
5) Is the Blackburn STB040A1508 made in the USA for a Buy American job?
Country of origin on the STB040A1508 is the United States, which is what utility and government specifications with domestic content clauses typically ask you to document. Cite the part number STB040A1508 on your submittal.
6) How is the Blackburn braid connector sold, individually or in pairs?
Each. One STB040A1508 is one braid assembly, so a three-phase connection takes three pieces.
