Steel City CI2408 – Frequently Asked Questions
1) What trade sizes does the Steel City CI240 insulated bushing come in?
The Steel City CI240 series insulated bushing runs from 1 inch up through 5 inch trade size: 1 inch (CI2408), 1-1/4 inch (CI2410), 1-1/2 inch (CI2412), 2 inch (CI2416), 2-1/2 inch (CI2420), 3 inch (CI2424), 3-1/2 inch (CI2428), 4 inch (CI2432) and 5 inch (CI2440). Order by the trade size of the conduit or the threaded hub it is going onto, not by the actual outside diameter of the pipe.
2) Do I need an insulated bushing on the end of my conduit, or will a plain locknut do?
An insulated bushing goes on the threaded end of rigid or IMC conduit to give the conductors a smooth, non-abrasive throat where they enter a box, panel or enclosure. A locknut only holds the conduit to the enclosure wall; it leaves the cut thread exposed to the wire jacket. The Steel City CI240 aluminum insulated bushing threads onto the conduit end for that protection, in trade sizes 1 inch through 5 inch. Use the two together, not one instead of the other.
3) What is the part number for a 1-1/4 inch Steel City insulated bushing?
CI2410 is the 1-1/4 inch size in the Steel City CI240 insulated bushing line. The adjacent sizes are CI2408 at 1 inch and CI2412 at 1-1/2 inch, so if you are matching a hub or a rigid conduit end, confirm the trade size stamped on the pipe before you pick.
4) What is the Steel City CI240 bushing made of?
The body is aluminum, with an insulating liner - that is what makes it an insulated bushing rather than a plain metal one. Aluminum matters on two counts: it keeps weight down on the larger 3 inch through 5 inch sizes, and on a job where the spec calls out non-ferrous fittings it satisfies that. If your drawing calls for a malleable iron bushing, this is not that part.
