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 ?

Thanks,
Bob

This is Turtle.

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

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

E-mail me if you want to discuss it.
