Panel feeders

[rrtdc]

Am feeding two new panels out of an existing distribution panel. The feeders are to be in seperate conduits. These conduits will run on same rack for a way before going in different directions. Need to put an opening (270 degrees by spec.) at the place where they head in different directions. My question is can these two feeders share a common gutter or junction box, or do they need to be seperate?

sharing is fine (Unless one is emergency)

Both of them are emergency, out of the same distribution panel.

What does that mean? :-?

every 3 -90's (270 degrees) they want a junction box according to spec?

omitting "emergency" in your original post sure could make a difference.:smile:
why its always risky answering inspection questions. 700.9(B) would lead me to think there would not be a problem, but that might depend on an individual's outlook as to "feeders" being considered "circuits". My OPINION would be no problem, but strongly suggest you ask your AHJ.

Sorry that I was not clear on the 270 degrees deal. Yes the specifications on this job say maximum of 270 degrees of bends before an opening instead of 360 degrees that the NEC requires. Thanks for the replys. That helps me out.

I recon that's aimed at lessened conductor damage during install.

That can be an obnoxious limitation.

Yes, particularly if it is ignored and then picked up on by a diligent customer.:grin:

It cost the company I used to work for $17,000 in copper alone, never mind all the Sunday DT for the 10 or 12 of us. OUCH!

Ouch is right! Who got the blame for the snafu? And, how many Sundays?

We had to replace two 800 amp feeders to a pair of chillers. .......... and no, we did not get to keep what we pulled out. :grin:
