Blackburn FB3D24-1 – Frequently Asked Questions
1) How long is the FB3D24-1 braid, and how much of that is usable span?
The FB3D24-1 is a 24 inch braid. That 24 inches is the overall cable length, so plan your span with the bolt holes at each end falling inside it rather than assuming 24 inches of free flex between terminations.
2) Is this a one-hole or two-hole braid connector?
One hole per pad. The FB3D24-1 is a 1-hole flexible braid connector, so it lands with a single bolt at each termination. If your pad drilling is NEMA two-hole spacing and the spec calls for two-bolt landings, a 1-hole braid won't satisfy it and you need the 2-hole version of the braid instead.
3) Is the Blackburn FB3D24-1 UL listed?
It carries UL file E3060 and CSA LR29625. Those file numbers are what an inspector or a submittal reviewer will want for a bonding jumper on a utility or industrial job.
4) What is the Blackburn FB3D24-1 flexible braid used for?
It's a flat, flexible tin-plated copper braid connector used to bond equipment that moves, vibrates, or expands, such as switchgear doors, transformer connections, bus expansion joints, and generator or motor bonding jumpers. The flat braid construction flexes without fatiguing the way a solid bar or stiff cable would. Each end has a single bolt hole, and it is sold individually.
5) Will a tin-plated copper braid corrode where it bolts to aluminum bus?
Tin plating over the copper is what makes that joint acceptable. The tin gives a dull, oxide-resistant surface and keeps bare copper from sitting directly against aluminum, which is the usual source of galvanic trouble at a bus landing. Prep and a joint compound suited to the pad material are still normal practice.
6) Do I get bolts, washers, or hardware with the FB3D24-1?
The braid is sold as a single piece, each. Bolts, nuts, Belleville washers, and any joint compound are supplied separately, so add them to the order if the pads aren't already hardwared.
7) Is this braid made in the USA for a Buy American job?
Country of origin on the FB3D24-1 is the United States, which is the line a government, transit, or utility procurement package normally asks for on domestic-content bonding hardware.
8) Should I use a flexible braid or just run a bonding cable between the two pads?
Use the braid where the connection has to move. A flat flexible braid takes repeated flexing, thermal expansion, and vibration across a joint without work-hardening, and its flat profile keeps a low, compact loop in tight gear. A stranded bonding cable with lugs is the simpler choice for a fixed, static ground run where nothing moves. Picking a cable for a hinged door, an expansion joint, or a rotating machine is what leads to broken strands and a lost bond.
9) What is the exact part number to order this Blackburn 24 inch flexible braid?
Order Blackburn FB3D24-1. That's the manufacturer part number for the 24 inch, 1-hole flat flexible braid, and it is the number to put on a submittal or a counter order.
