Splicing a Feeder

We have an existing 225A 120/208v 3ph 4w panel that is to be relocated. The existing feeder leaves the distribution panel and passes thru a junction box, (no connections, splices or taps) and to the panel.

Can I move the panel and then run new wire to the j/box and assuming there is sufficient room, splice the wires with either a terminal board or other splices? Purpose would be to now have to shut down the distribution board to run new feeders to the existing breaker, critical computer systems connected.

If its ok, can someone point me to the applicable NEC code?

Thanks
 
Feeders can be spliced as often as you like, no different then branch circuits.

There really is no code section that says this, more importantly there is no code section saying you can not splice a feeder.
 
We removed a 200amp disconnect that was feeding a 200amp panel and installed a 400amp panel. The 3/0's feeding the 200amp panel were about 3' too short to make it to the 200amp breaker located in the bottom of the 400amp panel. The neutral was good though.

I spliced the 3/0's with coupletaps in the 400amp panel and the inspector said no way. I thought about asking him to look at 312.8 but decided to let it go. I have successfully argued this section before but I just didn't think it would be worth it on this job. This was in Chicago.

You're just too soft. Al Capone would have been ashamed. :D
 
312.8 is pretty explicit even for a hard nosed inspector. Unless of course there is a local code prohibiting it.
 
I would recommend making the splice readily available for periodic inspections, especially large, important feeders.
