Steel City BU503-1 – Frequently Asked Questions
1) What size conduit does the Steel City BU503-1 insulated bushing fit?
The BU503-1 is a 1 inch bushing. It threads onto 1 inch rigid or IMC conduit, so match it to the trade size of the raceway, not the conductor count.
2) Is the Steel City BU503-1 bushing plastic or metal?
Plastic. It is a non-metallic insulating bushing, which is why it is used to protect conductors at the conduit end rather than to serve as part of the grounding path. If your inspector wants a bonded connection at that fitting, you need a metallic insulated grounding bushing with a lug instead.
3) Will the BU503-1 bushing work on EMT?
No. It is threaded for rigid and IMC conduit, which are threaded raceways. EMT is unthreaded and terminates with a set-screw or compression connector, so you would use an insulated-throat EMT connector or a bushing sized to the connector's threads instead.
4) What is an insulated bushing on rigid conduit actually for?
It screws onto the exposed threaded end of the conduit where it enters a box, panel, or enclosure and gives the conductors a smooth insulated throat to bear against instead of bare cut threads. The BU503-1 covers the 1 inch trade size. Standard practice on rigid and IMC runs pulling insulated conductors.
5) Does the Steel City BU503-1 come as a single piece or in a box?
It is sold each, one bushing per unit, under model BU503-1. Order by the count of 1 inch conduit terminations on the job.
