I am reviewing a set of plans for a two story multi-tenant commercial building. The service from the utility is 120/208 three phase and comes to a 600 ampere disconnect that feeds a meter stack. One meter feeds a house panel for the common areas, and two separate meters provide power to separate 200 ampere panels within the same tenant space. Do the separate meter feeds to the same space (isolated by fire walls from the rest of the building) constitute a violation of 230.2?

Re: Multi-tenant Retail Service
Looks to me like you only have one service. Why would you be in violation 230.2?

It would not be an NEC violation. Some utilities use separate meters for hot water heaters, ours meters electric heat separately from the rest of the tenant needs. It shouldn't be an issue unless there is a local requirement.

Re: Multi-tenant Retail Service
not that simple. usually fire walls mean separate structures, if seperate structures then need to use one of the "outside" of building definitions. Most use 2" concrete cover as outside, running pipe underneath to tenant walls. This is not always called and not always caught. AND there is some attempt to get around this by claiming that these are not separate services, that they are feeders. But be cautious and check with your jurisdiction for their interpratation.
A small fire in a closet could cause a whole mall to be shut down until rewired if passing thru other tenant spaces.
