[QUOTE="sellers, post: 72210, member: 2357"] Ok, so done a CU upgrade today, I'm not part of a scheme but i'm going to be using this for my assesment so i want it to be spot on. Am I right in saying the main earth of the DB has to be no less than half the csa of the tails? Do you guys generally upgrade the MET or leave it if its ok. Its one of those where you wind the conductors around a bolt and tighten it up about 4 bolts in total. Is doubling up circuits a big no no, or just not good practice. I bought a 10 way cu as its only a small semi but as I was putting it all together i realised there are 11 circuits. I can get away with modifying 2 sockets that are to the left and right of db on their own circuits but do i really need to for regs? Can you put limitations on the test results? The customer says his washing machines are pluged in behind them and they are built into the kitchen cupboards. Thus IR tests are out. Is it correct that I can add ze + (r1+r2) to get zs as my loop tester still trips the b6 mcb even on no trip. Cheers folks [/QUOTE]
