Definition of 'defect' for comments on existing installation

When filling out electrical certificates, for the comments on existing installation section, this points to 644.1.2 which says that "The person responsible for the new work...will record...any defects found, so far is reasonably practicable, in the existing installation.".

What do we class as a defect? - anything that is not up to the latest BS7671? There is no definition in BS7671. 

  • Yes. Any such defect will also be awarded a code. Code 1 or code 2 means as unsatisfactory. Code 3 means satisfactory because safety is still maintained, however it might not be to the latest standard but the inspector has determined it is still pretty safe. FI (further investigation required) really means unsatisfactory because further investigation may in fact reveal a code 1 or code 2 once a determination is made.

  • Homework again Jimi? Keep it coming!

  • I think you are referring to the "comments on existing installation" boxes on EICs and MWEICs, and not an EICR. So no codes are attributed to the defects in these 2 forms. After all, an EICR is a comment on an existing installation in its entirety.

    The defects recorded do not affect the safety of your new work, else they would have needed to be fixed (eg no main bonding where required). so are things like no RCD protection to socket circuits, when you worked on the lights.

  • I stand corrected, codes would not be awarded if it is not an EICR/PIR

  • We could keep this going all evening, maybe even for a week or more.

    Probably easiest just to sum it up as anything that is not as it should be to current standards.

  • I was in a punk band at school called the Defects. Only Report that mentioned this was a school report.

  • Probably easiest just to sum it up as anything that is not as it should be to current standards.

    I'd maybe want to exclude minor deviations from current BS 7671 though - e,g. red/black colour coding on cables, or equipment not complying with the current product standards (e.g. BS 5486 CUs or BS 3871 MCBs).
