I thought MK were supposed to be good? Wiring rant...

    I was replacing a single socket tonight with a double and thought I was playing it safe with an MK Logic Plus dual gang socket.

    I belatedly came across this IETF thread about this very same topic.

    The weird screw angle, torque-wrench requirement on initial drive, cable disappearing up the side of the screw, and the screw being made of cheese.

    As per title, I thought MK were supposed to be the chosen make for this kind of thing but it seems I'm wrong.
    Double socket in the bin and another trip to screwfix in the morning.

    Any recommendations for basic 2 gang sockets?

    I understand exactly what you mean with the MK Stuff, the correct technique takes much practice and frustration to acquire. Once mastered they aren’t bad to wire, but they could be made better.

    As for a replacement the BG range from Screwfix has never gave me any issues.

    I know of another manufacturer that is looking at a problem with angled screws cutting the wire when tightened after 40 years. Outsourcing manufacture is wonderful. :thumbup:

    Wonder how the screw ends are finished.
    If there straight cut them it's no surprise.
    I hate cost cutting

    I'm no spark, but i have replaced every switch and socket in two houses now with new MK stuff and have never had any of these issues?

    Use a correct fitting parallel screwdriver and twist the end of the wire back on itself for a good amount or clamping area.

    I will admit things get a bit tight when trying to stuff 3 ends of 2.5mm2 in there but it's not a big problem.

    I might be more Inclined to try another brand if they would put a bit of effort into how their stuff looks.

    I bought double gangs from Aldi. Appear to be ok, everything went in easy enough. Can’t remember swearing so they must be good!

    I tend to go Hager for wiring accessories nowadays, they seem to be reliable and well made! Or cheaper end BG stuff isn't too bad!

    I've used MK sockets at home and they are a bit crap now. The screws are definitely way to soft and even with a good fitting screwdriver they can chew up very easily. I'm getting more and more P'ed off with manufacturers selling crap products at high prices and just trading off a once good name!

    I bought an MK single socket recently. Wasn't bad but quality not the same.
    It was pretty cheap - why not price it a bit more for quality?
    Considering how much electricians charge an extra £1 on a socket is neither here nor there!

    i found myself fitting loads of British general their terminals are surprisingly good,

    but i will only buy mk oven isolators and fused spurs
    it also helps to grind screwdrivers to a perfect fit

  14. This discussion has been on here before. I started one of the threads. I will not be buying any more MK sockets, they are the worst quality I have come across and the styling is "Marmite".

    Business has forgotten the difference between brand and manufacturer.
    Moore and wright made heirloom quality tools.
    Investment group buy legendary name and put it on schmoo thinking’s its just branding and does it matter:mad:

    Got a £2 generic socket from Wickes - much better!

    Now... a question for the sparks, if anyone is still watching... :D

    What I was doing was replacing a single socket with a double socket, and an FCU supplying a 4 gang on 7m of 1.5mm trunked flex:

    upload_2019-11-9_18-33-25.png



    I then tested the sockets with my trusty Robin:

    upload_2019-11-9_18-34-41.png


    0.58 ohm on the new socket, bang on what the old socket was showing.

    I then tried it on the extension and the first time it came out at 0.78 ohm - to be expected, I guess, given it's a spur on flex, and well within spec.

    But I then tried it again and, even though the "No Trip" button was on it tripped the RCD. Flipped it back on again, re-tested, and it did the same again although I noticed the Robin flash "NOISE" just before the RCD tripped.
    Is this to be expected and/or anything to worry about?

    have you tested your tester on a separate circuit preferably on the other rcd
    could be an earth leakage somewhere else, then when tested its sending enough current past the rcd that its tripping.
    pretty simple to prove either clamp the main earth
    or turn on one circuit at a time on the board

    Yeah - I use it in the garage whenever I fiddle with the sockets, and that's on its own RCD
    And, of course, it's ok when plugged into the socket at the other end of the spur :dontknow:

    another option is the rcd
    as ive got an MFT id just test the rcd as well check earth leakage with a clamp, might be easier for you just to swap the rcds then test again.

    rcds do go faulty i have a batch of rcbo's that wouldn't trip even 5X rated

    Probably as above a little leakage already on the RCD, happens with lots of SMPS. It's one reason I like RCBO'S.
    Hopefully, if and when they get to the 19th edition, the suites that don't work in the real world, will of hears of Time Delay rcds, for downstream along with 10ma, and 100ma or 300ma, for main supplies. You would think the only thing you could buy is a 30ma.
    It's too common now for 2 or 3 to be in a chain and its pot luck what one will pop, as there is no allowance for discrimination.
