Hello:

When they say a house has, e.g., 150 amp service, is that 150 amps at 115 V,
or 150 amps at 220 V ?

This is Turtle.

150 amps in 115 volt service or 300 amps in a 220 volt service.

WRONG. It means 150 amps at 220 volts.

You can have 15 --- 20 amp single 115 volt breakers or 7.5 --- 20 amp double
pole breakers at 220 volt service.

Wrong again. It's perfectly OK for the ratings of the individual branch
circuit breakers to add up to a *lot* more than the rating of the main
disconnect. This is because the branch circuits will not _all_ be in use, at
full capacity, at the same time.

E-mail me if you want to discuss it.

The OP would be better off posting his questions publicly so that others have
the opportunity to correct your errors.
