Metallics IPB300 – Frequently Asked Questions
1) Will the Metallics IPB300 insulated bushing thread onto 3 inch rigid conduit?
Yes. The IPB300 is a 3 inch insulated bushing that screws directly onto threaded rigid conduit, so it mates with standard 3 inch rigid or IMC male threads at the end of the run. It is a plastic bushing intended for rigid conduit.
2) Is the Metallics IPB300 bushing metal or plastic, and does that matter for a grounded run?
Plastic. The IPB300 is a molded insulating bushing only, so it does not carry a bond or ground path. If the job calls for a grounding bushing with a lay-in lug, that is a different fitting entirely, not this one.
3) Are Metallics insulated bushings made in the USA for a Buy American job?
Country of origin on the IPB300 is the United States, and it is flagged both Buy American compliant and ARRA compliant, which is what federal, school, and municipal procurement typically asks for on electrical fittings.
4) What does an insulated conduit bushing actually do at the end of a run?
It caps the exposed conduit thread with a smoothly rounded insulating surface so conductors are not cut or abraded as they are pulled through and as they sit under vibration over time. The IPB300 does that job at a 3 inch opening, which is where a large pull of big conductors is most likely to be damaged on a bare thread.
5) Can I use a 3 inch insulated bushing instead of a plastic push-in bushing on EMT?
No. The IPB300 threads on, so it needs a male conduit thread to grab, which rigid and IMC have and plain EMT does not. For EMT you want a snap-in or push-in type bushing sized to the tubing, or a threaded bushing on an EMT connector hub.
6) What does a jar of 25 Metallics 3 inch insulated bushings weigh and how big is the container?
The jar comes in at 2.5 lbs, with container dimensions of 10 x 8 x 4 inches. Light enough to keep a jar on the truck without eating a shelf.
