Double circuit in the distribution box

This guide covers split load vs dual RCD vs RCBO board configurations, circuit arrangement and allocation, BS 7671 labelling requirements, type testing under BS EN 61439, SPD installation, wiring best practice, and the common mistakes found during EICR inspections. Presented single line diagrams and layouts are generalized since they depend on the type and voltage (s) of the substations. The physical size. Use electrical diagrams to see where circuits go. Diagrams are like maps for your wires. Make sure the breaker matches what it protects. This stops fires and helps everything work right. The supply wires from every energy meter are ejected and carried to the distribution fuse board of every floor. Wiring a Distribution Board is vital in any electrical installation. The Main feeder cable to the Distribution Board should be able to handle the total power anticipated when all the sub circuits in the Distribution Board. A distribution board or distribution box is where the main power supply is distributed to multiple loads.
