I need a Code refernce if there is one. Existing store being seperated into two units. Each will have their own service. Low bidder wants to use the existing single raceway to the rooftop units with feeders from the two seperate services for the seperate rooftop units. Sounds like a hazard to me but, I would sure like to back it up with a Code reference. 210.25 is for dwelling units to common areas. 230.2 is for services. Is there a rule about feeders in commercial areas ?? Alan--
Alan- the only thing that I found is in Art. 225 Sect. 225.31 & 32. I don't know if this helps you but it does convey the thought of different feeders from different sources and how to handle them. Beyond that, your on your own. See Ya in Traverse City in September.
George, Found the solution in section 215.5. If the low bidder wants to mix feeders from two different services then the AHJ (me)will require compliance with 215.5 and have copies posted at each service. Alan--
Iwire, I'm the local AHJ but, there is the right to appeal any decision I make to the local review board and / or to the State Building Commissioner. I've had two appeals in 25 years and was supported both times. Alan-- The Code is to promote safety and I feel that circuits from two seperate services in the same raceway is creating an unnecessary hazardous condition. Alan--

The maxim of the law is that whatever is not forbidden is lawful. The code forbids having both emergency and none emergency conductors in the same raceway. I believe it is silent on the issue of conductors from two services in the same raceway. I would agree that it is an unusual installation but if it is not forbidden by the code then you will have to hang your decision on clear and present danger. Iwire may have hit on a remedy in that the rules of your states utility regulatory agency may forbid the mingling of conductors from two different meters in the same raceway. -- Tom Horne

One raceway to/thru roof to 'units' from two tenant meters??
Sounds like a 'design' thing. I know of no Article to prohibit this.
From the safety angle, are the terminations identified?
We (NJ) have the same basic Appeals system that you described; we also have DCA (State) people we can get interpertations from, BUT, they are that person's OPINION. The AHJ has the 'Final" decision, albeit subject to the Board of Appeals.
Usually, I try to 'work out' situations one on one, not saying it works all the time, but......
