on a 3 phase 240 volt service . is it a fact that when installing a sub panel from the main panel you can't bring the neutral wire to the new panel because of danger of neutral and 208 v leg.? this is what another electrician said to me and i am not sure. Thanks for your help...
 
certainly no reason that I know of that you can't. If you anticiapate no 120 volt loads, then there would be no requiremt for the neutral and perhaps it's absense would serve as a caution about connecting 120v loads.
However, from my experience, if the "electrician" connecting loads to this sub-panel is not knowledable enough of high-leg systems, he might be just as apt to connect his 120v load to the grounding means.

is it a code violation to carry the neutral wire to the sub panel ? i was told its been against the nec for 25 years.

Fact is, there are many instances where the neutral is specifically carried to a subpanel... one that is 120/240 1? 3-wire. This 1? subpanel helps reduce the confusion of running single phase line to neutral loads out of the three phase panel and leaves more slots available for two- and three-pole breakers.

i think he was saying you can't bring the neutral with a 3 phase feed for the added sub panel. it has to be a single phase sub panel.

I don't read minds :wink:

But in any case, he's wrong.
