    As it says - what code should I be giving to a metal CU where the cables come straight in through the knockouts without any form of protection. Meter tails and main earth enter through different apertures 'n all.

    C2 in my book. no cable restraint and chance of shorting out to CU casing. potential dangerous. the different holes i'd code as C3 as the small eddy currents on a dom. will not cause a problem

    Are the tails insulated and sheathed?
    Is there any signs of damage /abrasions to the tails?
    And is it TT?

    Whilst I agree that in reality it's unlikely to pose any real issue in a domestic installation I would still C2 it as it is not something which I would condone.

    C
    C2 potentially dangerous?
    If there was evidence of thermal effects on the enclosure then that's the only time I would C2 it for tails entering different holes.
    Just my opinion tho.
    I'd be more concerned with the lack of protection to the cables entering the enclosure.

    It does have the potential to be dangerous, although as stated with the loads in a domestic installation this is unlikely.

    The earthing conductor must pass through the ferromagnetic enclosure together with the live tails. I'm not sure if that was what you were asking though.

    What do you think would warrant a C1?

    Which certs are you using? The ones in BS 7671 don't have a check list!

    Access to live parts a major issue on that installation by not fitting blanks, Knockouts with no glands and tails showing signs of damage. Tail gland kits are not expensive and make such a neater looking job. The MET appears to have a 16mm from DNO cut out to MET block then a 10mm run into the consumer unit, also there is only 1 10mm bonding cable from MET block which would mean only 1 bonding cable running to incoming gas or water? the lack of labeling on the CU and MET also shows signs of a cowboy installer grab the cash and run jobby to me.

    also there is only 1 10mm bonding cable from MET block which would mean only 1 bonding cable running to incoming gas or water

    Or even to both via one cable ;)

    Which doesn't even have to be continuous.... but is good practice to be a single cable

    Then your teacher was correct,both services sometimes require bonding, running a cable to each can cover that requirement
    there is however,more than one way to skin a cat :) and because something is done correctly,it does not mean there are not other permitted means to comply

    Quite a lot of electrical requirements can be achieved with differing solutions, it can be elusive sometimes finding justification for another persons method

    I suppose that is why electricians are regularly disputing or interpreting regs with one and other,they can have differing and compliant means to reach the same outcome

    Exactly why i love this trade i learn new ways all the time. My boss would always want me to install separate bonding to incoming gas and water and thats what he prices for so i do as he says, but every spark is different and as i say im learning all the time and loving it.

    Standard finger -if you can poke something 12.5mm in dia and 75mm long and touch and exposed part then it needs to have a gromit/ gland fitted.
    I remember my collage lecturer finding a standard finger amusing. I don't know why?:rolleyes:
