    The transformer is dimensioned based on the max capacity of the houses in the neighbourhood, which are standardised.

    100 houses with 200 A main fuse each? Supplied by a 20 000 A transformer (plus safety margin obviously).

    If cryptoboy wants a non-standard main fuse size that requires an upgrade of the transformer, he has to pay for that.

      No, it isn’t. They use considerably smaller, cheaper transformers, based on the maximum expected load. A 500A transformer might serve ten 200A users.

      Those ten users might never use more than 400A total, even though each of them might use 150A+ from time to time. It doesn’t make sense to install a 2000A transformer when it will never see more than 400A.
