What is the panelboard capacity (V & A) for 7-eleven type convenience stores, w and w/o gas station?

[AdamH78]

Would like to know typical voltage and amps for the main service of 7-eleven style stores, with and without accompanying gas station?

There's no 'one size fits all' answer, it would depend on many things such as whether the convenience shop has a bakery etc.

As far as voltage goes it should be 240/120vac and as far as the size of the service needs to be at a minimum of 400 amps. As @Marvo stated there is not enough info. You should have engineered drawings on a job like that tell you the voltage and amperage
