Hi all,
Can anybody tell me where I can buy 5m of 12 core electrical wire?
I am rewiring my camping trailer and can't find 12 core wire anywhere in Aus.
Thanks in advance
Danny

I assume you are planning to rewire a 12 pin trailer connection...
... if so, 5 of those pins are for 'heavy duty' cable for things like running the camper fridge or charging a battery in the camper.
The size of wiring used in the 5 core or 7 core 'trailer' cables is nowhere near heavy enough to carry that sort of current without significant voltage drop.
Most people will use 7 core cable, and run alongside it heavy cable such as 8B&S (8 sq mm cross section).

Many people don't bother with the 12 pin plugs, and use a 7 pin plus Anderson Plug - there carry a lot more current.

Hope this helps.

Danny,
any electrical wholesaler such as Lawrence&Hanson, CNW, Auslec, etc will be able to help you out with the cable and accessories, just make sure you get flexible cable (multi stranded) 1.5mm (per core diameter) should be enough to run all the trailer lights, brakes and the like, any major power requirements will need an anderson plug from the tow vehicle to the trailer

hope this helps

Cheers

Doc

1.5mm bit small for brakes..

The smallest we can buy is 2mm in a 5 or 7 core, minimum 5-6mm is ideal for trailer brakes.

I think he is talking about 1.5mm squared?

Nobody does 12 core cable suitable for what you want to do, 7 core is it.

We usually make up looms if we can't buy it off the shelf to suit what we are doing.

Sorry not true.
Once you step into the world or real electrical cables, an great deal of things are available

12 core 1.5mm@ flex is reasonably common in theatrical lighting and can be purchased from any good electrical cable supplier.
I have nearly 200 meters of the stuff in my shed.

heavier multicore flexes can be had and are quite common in control cables for a variety of electrical items including cranes, lifts and the like.
2.5mm2 is far from uncommon

far less common are cables with a mix of cross sections.

3mm automotive cable is arround 1.1mm2,... 4mm automotive cable is arround 1.8mm2,...5mm automotive cable is arround 2.9mm2.

BUT
I'll go with what others have said...forget the 12 pin plugs, 7 pin plugs for the lights and other better plugs and seperate cables are a better bet for the auxiluaries.

cheers

Hate to tell you yes it is true, most people who want to use a 12 pin plug and socket and are asking for 12 core cable will want to use at least 2 cores for battery charging (-+) and maybe another core to power a fridge.

Hence why I said "nobody does a 12 core cable suitable for what you want it to do"..... unless you 12 core cable can defy physics and is capable of providing feed to charge a battery and run a fridge (3 way)

It's called specifying the right product for the job.

I don't see the point in sending someone on a bum steer getting his hopes up and then telling him it's not suitable for his needs.

It depends on exactly what they want the cable for.
12 or more core cable in 1.5mm2 cross section is most certainly available....and very nice cable too

There are all sorts of things people run in trailers using 12 pin plugs, work lights, rotating beacons, battery supplies for a whole variety of reasons and with led lighting lots of things now become viable on light cable

If ya looking at running high demand circuits onto a trailer the 12 pin plug is simply not up to it, so why even worry about a cable for that application.

To put it bluntly the 7 pin and 12 pin rectangular plastic plugs are just rubbish any way, they are simply a shocking design in so many ways.

SO the question was...is 12 core cable available....and it most certainly is.

cheers

Trailer Cables

This is what is available.

Best to buy 7 core and add the heavy cables for battery charging and fridge.

Perhaps you can go to JAYCAR to have a look, it has a website and the nearby local store. But eBay also selling this kind of wire. stores.ebay.com.au/Volka-Lighting?_trksid=p2047675.l25, go to this store, and you find the wire selling for LED lighting products.
