Are Bushings required on 1 1/4" or Larger EMT

[icefalkon]

Has anyone ever heard of this before?

 

[iwire]

No and yes.

No not required yes I have heard it before.

I think 300.4(G) comes into play here. Never heard that pipe size mattered.

 

[jaylectricity]

I've always used bushings on anything 3/4" and above.

For what it's worth we were taught 25 years ago in apprentice school that the requirement was for 1 1/4" raceways and larger. I don' think that requirement ever appeared in the NEC.

Based on conductor size... (1 1/4" most likely has #4 or larger) And material PVC vs metallic.

Or 6s or 8s or 10s or 12s or 14s

...or Cat-5s or RG-6s or 18-2s or 18-4s or Cat-6s or...

In EMT - how would this be required?

might just be a jet line too.

You had indicated the most likely size in 1.25" would be 4 or larger, I disagree, I use 1.25" for 10 AWG often or a butt load of 14s for fire alarm etc.

Could be fiber as well. :grin:

And you would be required to put a bushing on that????

Don't make me go all 'English teacher' on you.... [Snake-neck]

'Most likely' doesn't mean always....

 

[LarryFine]

Remember, EMT connectors are not conduit.

 

[cowboyjwc]

Conduits containings conductors #4 or larger.

Thanks for the Frisco to English translation. I thought the same as Bob, until you used colors to point out your piss-poor grammar

 

[ggonza]

Yeah but you might want to wait to put the plastic bushing on after the jet line comes out. It can slice right through it, if your not careful.
