Blackburn FBE4H235A1-12 – Frequently Asked Questions
1) How long is the Blackburn FBE4H235A1-12 jumper braid?
The braid measures 12 inches (304.8 mm) overall, which is the L12 in the part number. That length is what gives you slack to bridge across a hinged enclosure door, a pipe joint, or a flexible conduit run without putting tension on the terminals.
2) What bolt size do the terminals on this Blackburn bonding jumper braid take?
The terminal hole size is 9/16 inch, shown as H9/16 in the part designation. A 1/2 inch bolt or stud passes through it with clearance; if your ground bus or busbar is drilled for a smaller fastener, use a washer to spread the bearing surface.
3) Is the FBE4H235A1-12 braid insulated?
No. It is a non-insulated braid, so the conductor is exposed along its length. Keep it clear of energized parts and sharp edges when you route it, and treat any point it can touch as a bonded surface.
4) Why use a flexible braid instead of a solid or stranded bonding jumper?
An extra-flexible jumper braid is what you reach for where the two bonded points move relative to each other: enclosure doors that swing, equipment on vibration isolators, expansion joints, and flexible conduit sections. Solid or stranded copper work-hardens and eventually cracks under repeated flexing; the flat braid construction takes the motion. For a fixed, static connection between two rigid points, a standard bonding conductor is the simpler choice.
5) Is this Blackburn braid made in the USA, and does it meet a recognized standard?
Country of origin is the United States, and it is built to NEMA. That combination matters on federal, municipal, and other domestic-preference jobs where the submittal has to show origin.
6) What exact part number should I order for the 12 inch Blackburn braid with 9/16 inch holes?
Order Blackburn FBE4H235A1-12. That single part number covers the assembled braid, 12 inch length, 9/16 inch terminal holes, non-insulated.
7) Is the Blackburn FBE4H235A1-12 sold individually or in a pack?
Sold each, one assembled braid per unit. Count the openings or joints you are bonding and order to that number; for a switchgear lineup where every door needs a jumper, that is one per door.
