Steel City BU504-1 – Frequently Asked Questions
1) What size conduit does the Steel City BU504-1 insulated bushing fit?
The BU504-1 is a 1-1/4 inch bushing, sized for 1-1/4 inch rigid and IMC conduit. It threads onto the conduit end, so match it to the trade size of the conduit, not the knockout in the box.
2) Is the Steel City BU504-1 metal or plastic?
Plastic. It is a non-metallic insulating bushing, which is why it protects conductor insulation at the conduit end without a separate liner. If your job spec calls for a metallic insulated throat fitting or requires the bushing to carry ground continuity, a plastic bushing is the wrong part.
3) Will this bushing work on both rigid conduit and intermediate metal conduit?
Yes. The BU504-1 is made for both rigid (RGD) and IMC conduit, which share the same thread pitch at a given trade size. At 1-1/4 inch it goes on either one.
4) What does an insulated bushing on the end of conduit actually do?
It caps the cut, threaded conduit end with a smooth insulating throat so conductors are not pulled across bare metal. Wire damage during pulls is the failure it prevents. The BU504-1 covers that at 1-1/4 inch on rigid or IMC runs.
5) Does the BU504-1 come as a single piece or in a bulk pack?
It is sold each (EA), one bushing per unit, so order the count you need for your terminations rather than assuming a bag quantity.
