    Electrics... Undersized earthing conductor 12th Feb 18 at 8:18 PM
    Looking at a past electrical installation condition report for a flat and an item raised was:

    Earthing conductor undersized to comply with current IEE regulations. Unable to upgrade as main cables fed from meter through conduit

    Is this something that needs attention? The past owner was letting the flat to tenants, so I assume it is not a big deal?

    Was it given a rating? The ratings can be summarised as:
    C3: Technically doesn't comply, but not actually unsafe.
    C2: Poor, not as safe as it should be.
    C1: Dangerous, get it fixed before it kills somebody.

    Most people would just ignore a C3.
    If it sticks, force it.
    If it breaks, well it wasn't working right anyway.

    If it's green-yellow insulated wire (ie after mid-1970s) it's probably undersized but adequate.

    If it's green, or bare straggly copper, it needs looking at.
    A kind word lasts a minute, a skelped erse is sair for a day.

    Without details of the supply type and characteristics; cross-sectional areas of the cables involved (tails and Earthing conductor etc.) nobody can answer it. As stated, surely the Report has highlighted the seriousness of the fault through the coding system for the Observations.

    For an old style Periodic Inspection Report any defect will be numbered 1 through to 4 (with information on the Report as to what these recommendations mean), or for a newer Electrical Installation Condition Report there will be C1, C2, C3 or FI.
