Dear Engineers

Apologies for lowering the standard of discussion here with my first and probably only question. I had some work done to my mains stopvalve recently. In the cause of this the plumber needed to remove and then reinstate the green and yellow cable. I now noticed that it is not very tightly fastened into the clamp - see photo, and easily wobbles. Also the warning label has disappeared.

My question is: It looks easy to fix and to get a new label. Happy to have a go myself. But is there more to it? Does it need testing, perhaps? In other words: is this for householder or for electrician to remedy.

Many thanks in advance if you can help.

    The following poem, by Hilaire Belloc, was published after with the first Edition of what came to be known as the 'Wiring Regulations" in 1882 (then titled 'Society of Telegraph Engineers and of Electricians Rules and Regulations for the Prevention of Fire Risks Arising from Electric Lighting) when it first appeared in the Journal of the Society of Telegraph Engineers and of Electricians (Vol 11 1882):

    Lord Finchley tried to mend the Electric Light
    Himself. It struck him dead: And serve him right!
    For 'tis the duty of the wealthy man
    To give employment to the artisan

    Some things haven't changed much since the 1st Edition. For example:

    • Of the 4 pages, there is half a page dedicated to the "great and the good" who put together the first Edition. Luckily this has shrunk to 2 pages of about 600.
    • The 1st Edition was publicly criticised by electricians, one periodical article running into two pages of detailed comment on the 4-page "rules" Fearful
      Now such criticism appears in on-line Forums and Social Media. (The latest DPC for Amendment 3:2024, which is effectively a single Regulation and two Definitions, received a large number of formal comments and heaps of discussion on social media).
  • It's not the only standard to have "poetry" in it. The following is from the C++ Standard, ISO 14882:2003 (and is still present in the current edition):

    "When writing a specialisation, be careful about its location; or to make it compile will be such a trial as to kindle its self-immolation".

    Though that's a Limerick, so not really poetry...

  • It's not the only standard to have "poetry" in it.

    I was mistaken (and have edited toe previous reply) ... it was not published with the 1st Edition, but some years later in 1898.

    Hilaire Belloc wasn't born until 1870, which means he'd have been 12 years old in 1882
