Where are conduit bushings required?
For IMC and RMC, a metal or plastic bushing must be installed on conduit threads at terminations, regardless of conductor size, in accordance with 300.4(F), unless the design of the box, fitting, or enclosure is such as to afford equivalent protection [342.46 and 344.46].
What is a conduit bushing?
Bridgeport’s insulating bushings are used to protect conductors inside rigid or IMC conduits when entering a box or enclosure. The edges of the bushing provide a smooth surface to help prevent damage to wire insulation.
Can I mix PVC and EMT conduit?
You can connect EMT to a PVC box using a regular EMT connector or a raintite one if outside. The only thing is that you will have to use a bonding bushing to connect to the EG.
How do you connect conduit together?
Quote from the video:
Quote from Youtube video: All you have to do is put an insert on each piece of conduit that you're trying to connect. And then use a threaded rod in between them to connect them. Together.
Can you mix rigid and EMT fittings?

Do you need plastic bushings on EMT connectors?
Senior Member. infinity said: #6 and smaller does not require a bushing on an EMT connector. Although they do not require an additional bushing IMO insulated throat connectors are terrible when pulling larger conductors.
What is plastic bushing?

Why is it important to follow conduit trade size?
One type of raceway is the conduit, which is mostly used in duct bank installation, and also building installations. As with any raceways, conduits also should be sized large enough to carry cables with them overheating and to prevent any insulation damage while cable pulling.
