[QUOTE="Traineeboy, post: 500667, member: 32807"] The max Permitted for 32a MCB Type B is 1.37 therefore 1.39 would fail if I was to use that measurement but I do it via Calculation ( which is the way I was taught) then I get 0.30 which is totally fine. Would I be getting a much higher Reading , taking the Zs via measurement because of parallel earths ? as 1.09 difference is a big difference got the r1 + r2 via testing at the board. end to end then Figure of 8. Took highest reading on the circuit. [/QUOTE]
