Steel City BU507-1 – Frequently Asked Questions
1) Is the Steel City BU507-1 bushing metal or plastic?
Plastic. It's a molded insulating bushing, not a metallic one, so it protects conductors at the conduit end but does not itself carry ground continuity. On a metal raceway you still rely on the threaded connection or a bonding locknut for the equipment grounding path.
2) Do I need an insulated bushing on the end of 2-1/2 inch rigid conduit entering a panel?
Where conductors leave a raceway, the end needs a fitting that protects them from the cut metal edge. A 2-1/2 inch insulated bushing like the BU507-1 threads onto the conduit end inside the enclosure and gives the conductors a smooth insulating surface to bear against. This is the common approach on larger trade sizes feeding gutters, panels, and pull boxes.
3) Is the BU507-1 non-metallic bushing sold individually or in a box?
The BU507-1 is sold each, one bushing per unit, so order by the number of conduit terminations you need rather than by carton.
