An old hospital campus is being renovated into low-income housing. As part of this phase 4 buildings are being converted into housing units. Each building will have anywhere from 19-27 units, each with its own metered board, all electric appliances. We need to reconfigure the electrical distribution and my plan is to have each building have its own transformer and an exterior meter module, the reason being if I was to use one transformer to feed all the buildings, all building would lose power upon transformer failure. There is an existing utility tunnel that connects all the buildings and one idea was to have one xfmr power the campus and have all the meter modules in one building(the one building that has a utility room inside) and have all the feeders to the apartments run through these tunnels. The furthest apt is approx 300' from this utility room. Does anybody have any opinion on either method? Comments appreciated.

Less piping, fewer single points of failure to take down the complex.charlie tuna

Re: New Residential Service
no question--individual transformers feeding meter banks with main breakers built in. where and how many meter banks would depend on the physical size and height of the buildings... cost of feeders and voltage drop considerations would get very expensive.....

Read 225.30, .31, .32 and Charlie's post and it will be self evident that your original idea is a very good one.

Re: New Residential Service
I like the individual transformers better also, but I am wondering where the service point is. If the meters are at each building, isn't it the power company's responsibility to provide service to each building? Wouldn't that make it their decision?

Re: New Residential Service
it being a "low income" project, i'm sure the power company could provide the best service options. i don't know where the project is but you could always go to submetering the units and it might save money by buying power at a bulk rate. we did a building that originally had 52 power company meters installed and we went to one meter from the power company and installed a sub-meter system --- cost of job $36,500.. monthly savings-------$16,000.! check with your public utility commision....
