I recently did an addition for one of my clients which a service upgrade was needed.After doing the proper calculations we sized the new service accordingly. They had an existing 200 amp single phase 120/240 volt servive.
The new service was installed as a 400 amp 120/240 volt service, I fed it with 3 -500mcm copper conductors to a new (utility company supplied) 400 amp meter pan. The new meter pan fed 2- 200 amp exterior mounted raintight 200 amp disconnects in parellel. The disconnects were both fed with 4/0 aluminum to there respective mains.From there ,200 amp SER cable were run to there respective sub panels which were both 200 amp main breaker 40 circuit panels. The local utility company supplies us meter pans for any service over 200 amps. During the installation of the service i notice a label in the meter pan stating 325 amp maximum meter only. I was a bit in question about this label but completed the service installation. On final inspection the service failed becaused the local inspection company stated that my 200 amp main breakers had to be downsized to 2- 150amp breakers due to the overload capacity of the meter pan. I needed 400 amps to supply the dwelling and wound up with a 300 amp service due to the meter pan. I contacted the local utility company and the said the meter pan was rated for 400 amps to the lugs, my question is why is there a 325 amp rating on the meter itself? My customer paid for a 400 amp service and wound up with only a 300 amp service to comply with the meter rating.Again the utility company told me that meter pan was designed for 400 amp services and thats all they use.On the exterior box label it stated Millbank 400 amp 120/240 volt raintight overhead meter socket. Any views on this?
