LDC3 said:Usually only 2 of the 3 phases are brought inside a residential building. Each phase is 120º from the others. The voltage between any phase and ground is about 115V. The potential between any 2 phases is about 230V. When all 3 phases are available, it is 550V.
This message is mainly for Stuntman to education me. How do businesses get 3 phase power from the same distribution as residential houses if there is not 220V between each of the phases?Stuntman said:... but this is largely incorrect.
