I always have 124 and the PoCo says that is within the nominal limits.
I am also not sure you can tap these transformers. There is a selector
but it is only for the medium voltage inputs.

Why do Americans have such piddly little transformers? We have nice big things that serve 100 houses:

Our houses were usually farther apart and it made more sense to do the
distribution over long distances with medium voltage. Once they got
started that way it was better to only have a few basic transformers.
It does limit the number of customers who are dark when one fails.
After hurricane Charley, my neighbor was out, I had power so I could
string a couple of cords over to her house to get the essential things
going for her (water, refrigeration, lights, TV and a little window
shaker). I had enough cords and circuits available outside to get her
around 7 KVA.

That is still just 1 &2 family or small commercial.
Multi family and office buildings will be served by bigger
transformers.


Never heard of a transformer failing here. Usually power lines.


This one was blown up in a hurricane, maybe struck by lightning but it
went up like a bomb and there was oil everywhere.
It only took out 2 houses tho.
They had to fix the primary but once they did the rest of the street
came up OK. It took a few days to get to that transformer tho. The
neighbor ran off of my house.
