Blackburn FBC6-1 FLEX BRAID 48 KCMIL 6 IN LONG

The FBC6-1 is a flexible flat braid bonding jumper, 48 kcmil, 6 inches long, with a single-hole terminal for bolting to equipment. It's used where two bonded points need an electrical connection that tolerates movement, vibration, or thermal expansion, such as across enclosure doors, hinged panels, gutter and raceway joints, or transformer and switchgear connections. The conductor is tin-plated copper, so it holds up better than bare copper in damp or corrosive locations.

The FBC6-1 carries UL E3060 and CSA LR29625. That covers the US and Canadian listings, so it can be specified on jobs on either side of the border. It's also made in the United States, which matters on Buy American and federally funded work.

Six inches overall. That's sized for short hops, door-to-frame bonds, cover-to-body bonds, and joints in gutter or wireway where the two landing points are close together. Measure hole center to hole center on your opening before ordering; if the span plus the slack you need for movement exceeds 6 inches, step up to a longer braid in the same family rather than stretching this one tight.

The FBC6-1 is a one-hole terminal at each end, which is what you want for a single bolt or stud landing, typical on enclosure doors, hinged covers, and small equipment pads. If your spec or drawing calls for a two-bolt NEMA pad connection, or the terminal has to resist twisting under load, you need a two-hole braid instead, not this one.

Flat braid flexes. On any joint that moves, a hinged door, a vibrating motor, an expansion fitting in a raceway, a stranded conductor work-hardens and eventually cracks at the lug. The FBC6-1 is built as a flat flexible conductor for exactly that duty. On a fixed connection that never moves, ordinary stranded copper with a compression lug is the simpler choice.

The braid is tin-plated copper, which resists the oxidation and sulfide attack that dulls bare copper in wet, coastal, or chemically aggressive rooms. Tin plating also makes it the safer pick where the braid lands on aluminum bus or an aluminum enclosure, since it keeps bare copper off the aluminum surface. Use an approved joint compound on the bolted connection as the equipment instructions require.

It's a 48 kcmil braid. For reference, that sits between 1 AWG and 1/0 in cross-section, so it covers bonding jumper sizing where the drawing calls for something in that range. Confirm the required jumper size against the overcurrent device or bus rating on your job before you land it.

Sold each. Order one per bonding point, so a panel with two hinged doors takes two.

Blackburn FBC6-1. That designation carries the family (FBC flexible braid connector), the 6 inch length, and the 1-hole terminal configuration, so a distributor picking from a bill of material can read the whole spec off the number.
