one meter base two meters .Not enough information.
How many meters?
Or is it a CT service?
What is the calculated load?
if i size them for 300 amps 250 KCM ??????????????????????????Sounds like a single set of service entrance condcutors to two meters and then to a 100 and 200 amp service disconnect. You'll need a load calculation to determine the conductor size ahead of the meters. I guess without one you can just size them for 300 amps.
For a commercial building, not unless you can show a calculated load of 255 amps or less.if i size them for 300 amps 250 KCM ??????????????????????????
Agree with you 100%. Now with some states are going to ban natural gas in new homes then down the road make existing homes loose thier natural gas and some homes required two EV chargers wonder if some of larger all electric homes would require a minimum of a 300 amp service if they do not have load management system &/or PV with possible battery storage. I have installed just a two hundred amp three phase service in machine shops & plastic injection start ups where money was tight and tried to talk them into getting a 400 amp service. Had to come back in a few years to upgrade the service.If you install 300 kcml you have a 255 amp service. That may be ok for now, but future tenants could add more load. In WA, we have to install an engraved label stating the service size is 255 amps
