Bridgeport Fittings BJ-100 – Frequently Asked Questions
1) Which Bridgeport bonding jumper do I need for 3/4 inch EMT?
Use the BJ-100. Bridgeport's bronze bonding jumper assembly is sized in three ranges by conduit size: BJ-100 covers 1/2 inch through 1 inch, BJ-200 covers 1-1/4 inch through 2 inch, and BJ-400 covers 2-1/2 inch through 4 inch. Pick the range the conduit falls in, not the next size up.
2) Can this bonding jumper be used on copper water pipe, or is it conduit only?
Both. The Bridgeport bronze bonding jumper assembly is intended for use with EMT, rigid conduit, or copper water pipe, so the same part handles bonding a metallic water piping system as well as raceway.
3) Is the Bridgeport bonding jumper UL listed for inspection sign-off?
It is UL listed under file E20412 and meets the NEMA FB-1 standard for fittings. Those are the two things an inspector typically wants to see on a bonding jumper in a commercial or institutional job.
4) Why is this bonding jumper bronze instead of plated steel or aluminum?
Bronze with a natural (unplated) finish is used because it resists corrosion and keeps a clean conductive surface at the clamp points. That matters where the jumper sits on damp copper water pipe or in a mechanical room, since a corroded contact face is what kills a bonding path over time.
5) What does a bonding jumper assembly actually do on a conduit run?
It carries the equipment grounding path around a break in the metallic raceway, for example across a concentric or eccentric knockout, an expansion fitting, or a length of non-metallic pipe, so the run stays electrically continuous. On copper water piping it ties the pipe into the grounding electrode system. It is not a connector and does not terminate conduit into a box on its own.
6) I need to bond several sizes on one job. Can I standardize on one Bridgeport jumper?
Not on a single part, but three cover the usual commercial range. Between BJ-100, BJ-200, and BJ-400 you span 1/2 inch through 4 inch conduit, so stocking all three on the truck covers most EMT and rigid work. Each one is the same bronze construction and same UL file E20412, so the submittal reads consistently across sizes.
7) Is the Bridgeport BJ series made in the USA?
Yes. The BJ series bronze bonding jumper assemblies are manufactured in the United States, which matters if you are working a government, municipal, or federally funded project with domestic content requirements.
