I have a question about the electrical design for a project I'm doing the mechanical on (because I am nosey and want to learn!).
It is a campground with clusters of cabins fed from a single meter. These "cabins" each have full kitchen, bath, HVAC systems. The electrician has it laid out so the owner is feeding a cluster of eight cabins from one utility meter. The meter is off a current transformer at the secondary of the utility transformer. The feeder from the transformer is to a 1200A main panel with a breaker and feeder to each cabin's own 200A panel. All single phase 120/240.
On his drawing the electrician sized the feed to the "main" panel using Article 220 Part IV Optional Method -- I thought this is just for multifamily dwellings. This is multiple single dwellings.
How should he have sized feeder and branches?
