Most cables are 16A, so the outlets are 16A as well. Also UK uses 240V, not 230V. 32A circuit breakers would make the cables burn when overloaded.
- benj111 7y agoFlex cables might be 16amp, individual sockets are 16 amp though, so if you have more than one of those on a ring main...

- xxs 7y agonormal fuses (in the fusebox) still have to be 16A (B or C class), the main fuse can be anything 32-50A or even tri-phase 50A. >ring circuits up to 100m, cookers and electric showers up to 7200W Normally those tend to be 3phases. Of course it's possible to get over 16A on a single phase and a circuit breaker but that's quite a non-standard option. The issue is that if the fuse/circuit breaker is rated for 32A in a standard application (i.e. an outlet) the cables are likely to burn 1st.
- benj111 7y agoI think we might be getting our wires crossed :) I'm talking about the UK here, which I understood to be similar to the rest of Europe(?). That's a UK website and 3 phase isn't common here. I've just double checked my fuse box, and I have a 32 amp fuse for my socket ring main. Don't forget for a ring main the current is spread over 2 wires, so if theres 32amps power draw, theres only 16amp on each side of the ring.
