    For those who think they can't manage it.
    In light of the recent thread on hook up leads started by ShiftZZ (Dave)
    http://www.motorhomefun.co.uk/forum/threads/hookup-cable.91247/

    I thought I'd do you a simple guide to terminating ends.
    These plugs I just bought from a1 plant sales at £9.99 for two pairs delivered are very good quality.
    I always start with the earth as I find it easier to get that out of the way first.
    Strip long enough to be able to twist then double back on itself and be captive by both screws.
    Always best to try FILL the space with copper. 2.5 doubled over just fits nicely.

    This type of plug simple twists to lock. Align the arrows and rotate

    Tighten the grey backnut which grips and seals the cable entry

    The female end is no different to do but observe the line & neutral terminals will be reversed

    Best practice......
    If the earth is connected correctly to start with there is no possibility of accidentally connecting live or neutral to the earth terminal.

    To prove a point only yesterday we had a problem in the school we are working in, a dead short to earth.

    The sparky had put earth to live and live to earth in an unfirmiliar make of socket.....lack of concentration

    Good guide.

    Another bit of good practice:

    Wherever practical to do so the earth wire should be longer and the live wire shortest so that if the cable is pulled out the live disconnects first and the earth remains connected thereby giving the protective device the best chance of operating.

    Yes, agreed, Earth first is best practice..

    I also leave the earth tail a bit longer than both the Live and Neutral.. that way if the cable is pulled or stress put on the socket/plug... the earth is the last to be pulled out...

    Edit .. Snap.. lol

    And for those who require a reverse polarity lead simply swap the brown and blue wires at ONE END of the lead only.

    Then CLEARLY MARK the lead as reversed polarity.....a black permanant marker used on the plug and socket will suffice.

    In support of the quality of these particular plugs. Any force strong enough to pull the cable out would either pull out all three cores completely or pull the socket off the wall. First class gear.(y) DONT drive off with it in

    I always start by threading the cable through the cover FIRST, and then wiring the cable.

    Hands up all those who have ever forgotten to do that first! :LOL:

    What gibberish. In all my years of wiring, I have never ever done such a stupid and incompetent thing. :sneaky:

    When that happens you never notice until you've finished all the connections :rolleyes:

    Or, cut through the cable, slip on the cover and then join it all back up again with a bit of terminal block, or just strip the wire and twist it together then strap up with a bit of lecy tape. :whistle:

    My only addition to the excellent advice (by the OP!) would be to give the terminals a spray with WD40 or similar before putting the cover on. The plated screws into brass terminals corrode fairly readily. An alternative that I use is to dip the prepared wire ends into industrial PJ before pushing them into the terminals.

    Thanks everyone.
    Thank you Techno100 for the link with all the pics.

    I don't understand spraying WD40 inside a plug? I thought electrics couldn't get wet---have I not followed you properly?
