[QUOTE="ProDave, post: 552842, member: 6969"] First you need to determine what the THREE red cables from the MCB do. Turn off the power, remove all three from the MCB and check with the multimeter if any of them show continuity from one to another. If they don't then connect them one at a time to the MCB, and with everything else on the CU switched off go and see what works. That will tell you what each of the three cables feeds, then you can make a plan for how to improve it. If any 2 show continuity between them report the findings back here before trying that test.
