Confused, I turned off an MCB to isolate a lighting circuit to change a switch panel. I ended up not doing it but when I switched it back on, no power. The MCB isn't tripping but I have no power. All the other circuits are fine. I have tried dropping the main switch while resetting this circuit but to no avail?
Can anybody point me in the right direction?
Many Thanks
