Blackburn FBB8-1 – Frequently Asked Questions
1) What is the Blackburn FBB8-1 flexible braid used for?
The FBB8-1 is a flat, flexible tin-plated copper braid jumper used to bond across a joint that moves or has to be broken for service: switchgear doors, transformer cabinets, hinged panel covers, equipment frames, and bus connections where a rigid conductor would fatigue. It is 24 KCMIL, 8 inches long, with a single bolt hole at each end.
2) Is the Blackburn FBB8-1 UL listed for grounding and bonding?
It carries UL E3060 and CSA LR29625. That pairing is what most electrical inspectors and institutional specs are looking for on a bonding jumper, and it is worth quoting on a submittal.
3) How long is the Blackburn FBB8-1 braid, and is that the overall length or hole-to-hole?
The braid is 8 inches, listed as cable length. Plan your span on that 8 inch figure and allow slack so the braid flexes rather than pulls on the terminals, which is the whole point of using braid instead of solid strap.
4) Does the Blackburn FBB8-1 braid come with bolts or hardware?
No. The FBB8-1 ships as a bare 1-hole braid jumper sold each, so the bolt, nut, and any flat or lock washers come from your hardware. Match the bolt to the pad it lands on.
5) Should I use a flexible braid jumper or a solid copper strap on a hinged equipment door?
Use the braid. Anywhere the two bonded parts move relative to each other, a hinged door, a vibrating motor frame, a bus expansion joint, a solid strap work-hardens and cracks at the bend. The FBB8-1 is built as a flexible flat conductor for exactly that duty. Solid strap is the right choice only on static connections between parts that never move.
6) What size is the FBB8-1 braid in KCMIL, and how do I know it is big enough for my bond?
The FBB8-1 is a 24 KCMIL braid. Size your bonding jumper from the NEC table that applies to your installation (equipment grounding conductor or bonding jumper sizing against the upstream overcurrent device or service conductor size), then pick the braid that meets or exceeds it. If your calculation lands above 24 KCMIL, step up to a larger braid rather than doubling this one.
7) Why tin-plated copper braid instead of bare copper for a bonding jumper?
The tin plating on the FBB8-1 braid slows oxidation on the strands and at the bolted terminals, which matters in damp, outdoor, or corrosive rooms where a bare copper braid can green up and add resistance at the joint. The copper core carries the current; the tin protects the contact surface.
8) Is the Blackburn FBB8-1 made in the USA?
Yes, country of origin is the United States. That covers most domestic-preference and Buy American language on government, healthcare, and education purchase orders.
9) How do I order the Blackburn braid and what exact part number should I put on the PO?
Order it as Blackburn FBB8-1, sold each. That part number covers the 24 KCMIL, 8 inch, 1-hole flat braid. Quantity is per piece, so a panel needing a jumper on each of four doors takes four.
