Blackburn FBDRL ROLL,FLEXIBLE BRAID 76.8 KCMIL

The FBDRL braid is sold by the foot, so you order the exact length you need for each bond rather than a fixed pre-cut piece. Order quantity equals feet of braid.

It is a 76.8 kcmil flexible braid. That is the cross-sectional copper area to compare against your bonding jumper sizing calculation, not a stranded AWG cable rating.

That is exactly what this is for. The FBDRL is a flexible, flat braided conductor, so it absorbs movement and vibration without work-hardening the way a solid or rigid bar does. Typical uses are bonding across busway expansion joints, transformer and motor frames, and equipment doors or hinged panels.

The FBDRL is supplied as bulk braid on the roll, cut to the footage you order. It is part of Blackburn's two-hole flexible braid connector line, so plan on terminating the cut ends yourself and specify the ferrules or two-hole pads and the bolts, washers and antioxidant compound separately.

Tin-plated copper. The plating is what you want where the jumper sits outdoors, in a damp vault, or against dissimilar metal hardware, since bare copper corrodes faster in those spots.

Flat. A flat braid lays against a bus bar, frame, or pad face and takes a two-hole bolted termination cleanly, which round braid does not do as well. If your landing point is a round lug or a compression barrel, flat braid is the wrong geometry.

Country of origin is the United States, which is the line a federal, military, or Buy American funded project will ask you to document for bonding material.

Flexible braid like the FBDRL is intended for bonding and equipment grounding connections where flex is needed, not as a substitute for the conductor type your drawing or inspector calls out for a grounding electrode run. Size it off the 76.8 kcmil copper area against the jumper table your job is engineered to, and if the spec names a stranded or solid conductor, use that.
