What is the min specification for the hookup cable?
a plug a socket and some wire
2 plugs no need for a socket
I would think 16 amp cable
I meant was there a specification for cable/wire size? BS Standards, CE etc etc,,,
Some are quoting :
3183Y 1.5mm (16 amp rated) flexible cable.approved by BASEC (British Approvals Service for Electric Cables)
Then you get "These are top quality 2.5mm sq cables and not the inferior 1.5mm cable sold by other dealers."
As said it needs to be minimum 16 amp rated, this will be 1.5mm at 19 amp
However 2.5 is preferable for being more robust and lower resistance
Get artic flex for ease of use especially in the cold.
2.5 won't be any more robust - if you drive over it or hit it with something the effects will be the same as with 1.5 The resistance will be slightly lower but negligible for this application. The only real difference will be in volt drop - you will be able to have a slightly longer cable using 2.5mm. If anyone is that interested I will dig out a regs book when I get home and work out the exact lengths.
Eddie is right - Arctic is designed to be used outdoors, normal flex isn't.
(Was an electrician then saw the light!)
Worked at an electrical wholesaler for 10 years, definitely artic is what you need if you get 2.5 you will be sure it's strong enough for anything you might do with it and it's not a lot dearer than 1.5 in comparison
If we're going to start quoting regs then 2.5 is recommended, as I said in other threads the earth loop impedance can be too high with 1.5 especially when people start extending it.
Thanks Techno -saves me going upstairs for my "Regs book". I like to keep it next to the bed - makes getting to sleep so much easier.
I believe the "Regs" also state that all new caravans must be supplied with a hook up cable when new.
Por dealer tried to palm us off with a scabby old cable. Gave them two choices - either give us a new cable, or I'd charge them to test the old cable.
So if I bought :
100 Metre Coil of 2.5mm 3 core Arctic Yellow Cable - NETARC253CY100 Arctic Cables remain Flexible at low temperatures. it is rated for use down to -40 oC at cold bend testing, and 25 oc for installation and handling,where as regular PVC stiffnes. The Yellow version is used in applications like site equipment , to denote 110 Volts, or for example Portable Traffic Lights. or any other conditions that require cold temperature electrical cables. The 2.5mm Stranded Conductor is rated at a maximum of 25 Amps
And some sockets, etc...(any specifications re sockets?)
I could get say 1x 50m, 1x25m and 1x 10m and 1 x 15m ?
Not having looked inside the sockets are they a pain to wire up?
86p per metre
Try and get fittings with screwed cable inlets, they grip the cable much better and keep a seal where the old type cut a hole in the sleeve are next to useless
Good one on left
these are images only no link to sellers
"16A straight commando socket"
"16A straight commando plug"
Both 230Vrating - will be blue in colour.
Max cable length stated in the Regs is 25M
Even I could do this...
Blue or orange, not yellow its the same stuff but yellow indicates 110 v which might just cause confusion somewhere along the line, no price difference
It really is very straight forward to wire up. Follow the instructions very carefully and you won't have any problems. Even I can and have done it.
Just made up a 10m cable using 2.5mm cable and these -
The electrical connections and the screwed flex retention grips were a dawdle however pushing the cable through the end of the units was very tight. Stretched the holes with a pair of fine nosed pliers and they returned to original shape \ size after the cable was through making a good rainproof fitting.
