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:

I was just about to add the same advice. Not from experience of course :wink:

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.

Pyjamas? What's industrial PJ?

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?

Since 2012 but longer in my dreams
I made up a lead a couple of years ago and the rubber is deteriorating it's cracked and split.
Is there a specific cable to use ?

Good advice here. I am not an electrician but I can spot an accident waiting to happen fron 1/2 a mile.

Some years ago I was involved with a bike race team and they had all the hook up leads for getting power at the circuit, one time I was helping he guys pack away and was unplugging and winding up all the cables. So that they had the option of plugging into the proper round sockets like we use and also a standard 3 pin socket as required, they had the 3 pin 13 amp plug piggy backed of the proper round plug and YES the 3 pin plug was live when plugged in by the round one.

When I pointed it out he said oh OK I will sort it out when I get home, you won't as I have disconnected them all I replied, could not leave it like that.

Electrics will work when surprisingly wet. Not very safely though when we're talking about mains. The WD 40 or PJ stops corrosion in the presence of condensation. Won't help if the plug or socket is full of water.:xsmile:

As an aside, PURE water, ie, distilled etc. is actually an insulator. It's only ORDINARY water that conducts electricity.

The campervan end of my lead has pinch terminal connections that are designed to pull out and be easily rewired if you drive away connected. As mentioned the earth comes out last ensuring the trip at the powered end goes before live wires are exposed on the floor.

I found this out by forgetting to unplug as I drove away..

WD40 ?
The killer of all things electronic ?
It is good if you can clean off residue and renew it regularly ( about every three weeks or so ).. But general use ?
You do know that the bloody stuff becomes hygroscopic after a while and far from repelling moisture actually absorbs it !
