Historical Wiring.

Zoomup

The old days where house main earthing leads were green 6.0mm2. Ring "mains" were wired in 2.5mm2 T&E with 1.0mm2 earth continuity conductors. And the use of plastic oval conduit in plaster was common.

Is this compliant? Please see picture.

    Why not compliant Chris? And for your bonus point, name the decade.

    But do the building regulations make it part of the installation?

    not to latest regs as cable out of zone, may predate cable zones if pre 1988 or so, and may have complied when built

    Yes it was common for cables to take more interesting routes than we usually get nowadays

    Yep, and the installation is dated from the 1970s. (Well before our time eh ebee). Clears throat.

    Weren't cables supposed to run vertically or horizontally from a point even back then, when hidden in walls?

    Probably. We always did apart from the cooker outlet cable which we put in diagonally to the outlet. That was mid 1980s as i left school in 84. Not sure when we started doing it properly. I don't know if it was compliant then, my boss seemed to think so and he was well thought of and always did a good job as far as i know. We stopped at some point so maybe he got picked up on it during an inspection.

    Guess at 1970s with the ash-type breeze-block, and the fact that 2.5/1.5 T&E was manufactured between approx 1969 and 1981.

    I think orthogonal routing was considered  best practice for many years before it snuck into the regs as a proper requirement in the late 1980s.
