I have a commercial project which includes a bowling alley with 208/120 service. The bowling alley electrical requirements state the 208V pin setters and some other 208V control power need to be on the same phase. On a 3 phase panel, this would mean pin setter 'A' would be on circuit 1/3, a space on 5, and controls 'A' on 7/9. Obviously this will create a lot of spaces in the panel and I tried my best to balance things around having some lanes across A/B, some across B/C, and some across C/A.
Stamping PE wants me to look into doing this on a 240V panel since it would be easier to install and would not have as much wasted space. To me, we would be pulling only 2 phases of the 208V service, possibly unbalancing the load upstream, and also not coordinating with the nameplate on the panel. Is there anything code wise preventing me from doing this? (Designed under NEC 2008, construction began under NEC 2011)
Thanks,
Ryan
