Blackburn FBS4H150A1-28 – Frequently Asked Questions
1) How long is the Blackburn FBS4H150A1-28 braid connector, and will it span my bus gap?
Overall length is 28 inches, with a cross section given as 5/16 by 3 inches. That is a long braid, intended for substantial expansion, misalignment, or movement between bus sections rather than a short jumper across a tight gap. Measure your pad-to-pad distance and allow for the loop or slack you want the braid to carry.
2) What standards does this Blackburn flexible braid connector meet for switchgear work?
The FBS4H150A1-28 is built to CEI 60694 and IEEE/ANSI C37.34-1994. C37.34 is the test code for high voltage air switches, so this braid is specified for switch and switchgear connection duty rather than as a general-purpose bonding strap.
3) Why use a flexible braid instead of a rigid bus link between switchgear connections?
A braid absorbs thermal expansion, vibration, and mechanical misalignment that would otherwise stress a bolted bus joint or the equipment terminal it lands on. The FBS4H150A1-28 is a flat, flexible conductor, so it flexes in one plane while keeping a wide, low-resistance current path. Use rigid bus where the geometry is fixed and nothing moves; use a braid at breaker connections, transformer terminals, disconnect switches, and anywhere two sections shift relative to each other.
4) Is the Blackburn FBS4H150A1-28 braid copper or aluminum, and will it corrode outdoors?
The conductor is tin-plated copper. The tin plating protects the copper surface and is what lets it land on aluminum bus or terminals without the bare copper-to-aluminum galvanic problem. Use an appropriate joint compound and the hardware called for by the equipment manufacturer on outdoor or wet-location joints.
5) Is the Blackburn FBS4H150A1-28 braid made in the USA for Buy American projects?
Country of origin is the United States. That matters on federal, utility, and public-agency jobs carrying domestic sourcing language, and it is worth citing the part number FBS4H150A1-28 on the submittal.
6) Is the Blackburn FBS4H150A1-28 sold individually or in a pack?
It ships as a single piece, sold each. Order one per connection point; a three-phase bus tie needs three.
