Maximum available power for standard domestic users is still only 3kW in many places. Might not be enough for a gaming PC, washing machine and microwave!
Exactly, a "cooking fuse" is not uncommon, which is two 16A lines to the same stove. That gives you 7360W to play with, something you won't reach in practice.
Alternatively, if you already have a multi-phase connection, then you would of course have the lines on different phases. If you have a 3-phase connection 25A main fuse is common, for single phase connections 35A is common.
Just to clarify here: when you talk about a "main fuse", you mean one that sits between the meter and the entire rest of the panel, correct? So individual circuits would be downstream of the main switch.
For context, most American homes have 240V split phase (single phase for all intents and purposes) service with a 200A main breaker.
Wtf do residential homes need 48 kW of power for? I guess it's nice to charge your car quickly, but other than that I'm struggling to think of any uses.
I have a microwave (1270W) and dishwasher (2400W) on the same circuit (230V, 16A). It didn't trip yet...
