Generally it's two-out-of-three-phases. You don't need 48A outlets in domestic use generally, but you totally could. The way e.g. my induction cook top is wired up is two bog-standard 250V 16A circuits, each from a different phase. Both these circuits end up at a single socket which the cooktop plugs into. Amusing side effect of this arrangement is that it's possible for the breaker to trip on half the cook top, leaving the other half perfectly usable.

If I used all my sockets at their maximum rating I'd trip that 100A, but equally I could put an 80A circuit off this and draw 14kW to charge my car without worrying too much (other than the cost!) Is a typical supply 100A on each phase (so 300A total), or lower?
- Doxin 4y agoThe supply to the house itself is typically three-phase. Pretty much no appliance needs all three though, so you'll often see two-phase at the socket.
