Which fuses do you use in the UK for the mains socket circuits? 10A? 13A? 16A? (1.5mm²)
Here in Germany it is usually 16A for 1.5mm² (however technically it should be 2.5mm² for 16A)
It sort of works like this:
1. RCD / breaker on the ring main (may be multiple rings - we have 4) .... 30A total per ring. That's 2.5mm cable.
2. Each socket is specced to draw max 13A.
3. Socket block is usually fused to 13A or 10A depending on if it's good or shit quality.
4. Individual plugs are fused 3A, 5A, 13A usually.
