>A ring circuit starts at a 30/32A MCB in the consumer unit, loops in & out of each socket / fused connection unit in the circuit & back to the same 30/32A MCB.
Minimum cable size is 2.5 sq mm Cu/PVC.
Why does it go back to the same 30/32A MCB? Is this yo have better ground-fault protection (since it's a TN system)? What type of curve do you have to use in breakers (B/C)?
The cable is 2.5mm2 and you use a 30/32A breaker? How is this wire protected for over Ampering?(sorry for my English)
