Situation: Hotel building with a 12.47 primary service. It has primary metering. Service entrance hits a primary fused switch then connects to a 12.47 to 120/208 dry-type transformer. Transformer connects to a panelboard with a main device. My client is installing a cell site on the roof of the building with an equipment room located on the same level as the above service equipment. The client desires a seperate 120/208 volt service from the utility. The AHJ is denying the plans because (his words follow):
"It is my understanding that since the building is served by a primary service the owners have the option of supplying what ever voltage that they
may need from that service. Thus the argument for Article 230.2(D) does not apply. Article 230.2(B)(1) states that additional services may be permitted
for multiple occupancies where there is no available space for service equipment accessible to all occupants. Space is available so that is not an issue.
The building already has 120/208 as the operating voltage therefore a second service is not permitted."
My contention is that the owners ability to supply "what ever voltage that they may need" is not relevant to meeting the standard set by the Article. Article 230 is specific to services, once the primary passes through the main device it becomes a feeder and is no longer subject to article 230. Therefore this case would meet the criteria to apply 230.2.D Different Characteristics which would allow additional services for different voltages, frequencies, or phases, or for different uses...
What do you all think?
