On our house we have a 3 pole / 3 phase main breaker but then everything else is 240v single phase inside the house, what sort of wiring connection happens between the 3 phase power and the rest of the house?
In: 1
It doesn’t. You just tap onto all 3 phases individually. Lights might be powered by A phase, power outlets powered by B phase, cooking appliances by C phase.
It doesn’t need to be arranged like that, it’s just an example. A lot of houses may only use one or two phases. The whole arrangement depends on how much power you’re expected to use and on what circuits.
