    GN8 9.3.1 Calculation of csa – armoured cable 118

    there are no requirements for supp or main bonding within the building supplied in question , SWA only used as a CPC on sub mains and not supporting main bonding. But yes quite right i think its a factor of 6 or something?

    Internal drainage pipe help

    If a cast iron internal drain pipe terminates outside into a clay drainage point is this still classed as extraneous conductive part. I am being super careful as an NICEIC inspector had me box off a soil pipe on a PME system earlier last month and dont want to come a cropper again.

    within a building supplied my a PME system it’s not possible to main bond the extraneous conductive parts effectively back to the origin. Resolution instead of changing to a TT system remove the extraneous conductive parts. Water pipe: this comes out the ground so change this to plastic and...

    client wont let me back into site

    i could never get access to the origin, turns out we could on my assessment and discovered the building sub main was off a PME 50mm SWA twin. thats the issue. a big mistake for me as assumed i could limitate it on the EICR
