    I won't dispute that.
    And to clarify SP didn't actually specify to remove trunking, only to remove the tails from the trunking. It was just easier to remove a few screws and the trunking due to the way the tails entered each end.
    A 3m 25mm² tails kit had been installed so no 'too long' excuses etc.

    Quite. It seems to me that many/most 'meter operatives' (many of whom appear to have very limited, and very specific, training) will simply 'walk away' from anything other than the most conventional of situations - which makes me suspect that I might well struggle to find one who was happy to connect SWA to a meter, no matter how the end of the SWA had been 'prepared'. I certainly would personally not dream of taking that 'risk'.

    Kind Regards, John

    Thanks all, as I'm not qualified, I think I'll ask my supplier what they will allow and go from there, I will suggest the SWA as an option and see if they'll accept it. Thanks again all.

    You're welcome.

    AS far as the Wiring Regulations are concerned, if you want the tails buried in a wall, your only two real options are to have both tails in (the same) steel conduit or to use SWA (which can be buried directly), and SWA is probably the simplest of those two options.

    If you used SWA, the only debate is to how it would be connected to the meter. Sunray believe that it could/should just be connected 'directly' but I, and others, don't think it likely that your supplier (or their subcontractor) would be prepared to do that. If I'm right, then, as I have said, the solution would be simple enough - the SWA could be taken to a 'box' (maybe an isolator) in the meter cabinet and, from there, a few inches of conventional cable could go to the meter.

    Let us know what your supplier says!

    Kind Regards, John

    The isolator is an excellent idea, in fact asking SP to provide one is the obvious first step.

    Well, it's just a watered-down version of the 'switch-fuse' that was initially suggested, given that, as in said in response to that suggestion, if the fuse is not currently 'required' (e.g. because of length of the tails) it presumably would still not be needed if the tails were buried.

    By the way, as a matter of interest, why have you recently taken to quoting the whole of a message but 'greying out' all but the little bit of relevance (rather than just quoting the 'relevant' bit)?

    Kind Regards, John

    Simply because I've been 'accused' of picking and chosing what I reply to (but that doesn't alter it) and quoting out of context.

    This way the whole message is there, including context.

    Fair enough. However, it should be pointed out to such 'accusers' that every quote (if created properly), even if only a 'partial' one, comes with a little arrow they can click on to see the 'context'.

    I suppose it doesn't matter, but it just looks a little 'messy' to me :)

    Kind Regards, John

    Yeahhh, hard to know what to do for the best, but it's easy to read face value quote (even if incorrect) and reply I admit I've done it myself.

    However ANY quote is better than no quote... one of my pet hates when struggle to understand a reply when it is not quoted.

    I totally agree. Without quoting, there is often 'ambiguity' as to what the reply relates to.

    A classic is that if there is a rapid sequence of brief messages from different people, along the conceptual lines of:
    1... "Yes there is"
    2... "No there isn't"
    3... "I agree"

    ... then, although it might appear that (3) was a response to (2), it's not uncommon that the author of (3) had seen (1), but not (2) when he/she wrote (3), thereby reversing the meaning :)

    Kind Regards, John
