So could run with FI, but obv that doesn't deliver a satisfactory report. Bit of a tricky one as it would have complied...

    PSCC on 460V Split Phase Supply

    Hi all. Been doing a bit of work on a pub out in the sticks with a 460V split phase Supply. When tried to test phase - phase PSCC my tester didn't play along. I was going to use the double p - n rule of thumb but then I got thinking, does this still apply to a 460v supply?

    Split Concentric Termination

    I'm no expert on split concentric (assuming that's what this is)......But an earth clamp doesn't seem the best solution to this (also as the earth cores appear to be insulated! This is for an eicr on a sub main but I'll have to do the remedial work at some stage. Any advice on how to...

    Low Ze, high(ish) R1+R2, Got a plan but just had an idea

    So Ze=0.02 and R1+R2 = 0.73 on a first floor ring main. Nearest submain is about 35m away, so that Ze's plausible, and even a slightly indirect route makes Ze=0.03 realistic. So MCBs are going to need changing to Type Cs. Unfortunately for that first floor ring R1+R2 of 0.73 is too high for a...
