Electrical wire query...

[tvout]

Hi all,

Just a quick question I'm hoping someone might be able to help me with...

I want to use some wire to power a small wireless security camera a distance from my house. I've been told bell wire is good as it's only 12v I need to use it with and it's very thin wire so could go through a smaller hole...

Thing is, if I look up wire I don't often find much listed as 'bell wire', I wondered what else it'd be called? Not being much of an electrical expert or anything...

Is the cable going overground or underground?

If its outdoors you shouldnt really use bell wire

[brundles]

Can you post the camera model?

Oh it's for overground...

It wouldn't be that bad if it got damaged or something chewed through it. Would it be against regulations etc. to use outdoor or is it just because it's quite easily damaged compared to thicker wire types?

Not sure what it would be, it's a cheapy hong kong thing I got off ebay.
The manufacturer is www.inesun.com.
Sorry...

Bellwire - http://www.screwfix.com/prods/17428/...ire-White-100m

That would do the job, provided its not a long run, but you'd have the problem of being able to tell which is positive and which negative as its not marked. If you have a multimeter to check then your OK.

Screwfix do a 2 core flex: http://www.screwfix.com/prods/14444/...Round-Flex-50m which I assume would be colour coded and if so would be OK too.

Should be fine outside at 12v - might want to put it in some sort of conduiting, for protection (only thin wire).

A few more details needed first, deffo need a model / make number. Then distance, and then to see if it needs 2 or more cores

This is the closest match I can find at the moment:

Distance wise, I'd say about 6-8 metres from the house.

Looking at that, all you would need is a multi-core alarm cable, I would steer clear of the 'bell wire' route, it's a bit cowboy-ish A 4 core cable would be small enough diameter to go just about anywhere, available at most diy stores / electrical wholesalers etc etc, and not expensive.

if it's being burried then i'd be inclined to use some braided cable and run into a jb with some choc block, then run it out with some 4/6 core alarm cable.


Main cable SY Braided Cable
Jb Plastic Junction Box
Alarm cable Alarm Cable

and some choc blok and armour gland from b&q, all those are examples. you might think it's a bit ott but saves using small alarm that may get damaged and those bits should set you back no more than £30-40 max.

OR do it with Bell Wire and save a fortune

There are regulations seeing as it is a fixed system, but you should be OK because it comes under Separated extra-low voltage systems (SELV) because the power supply feeding it is probably class II and is under 30Vdc.

The only thing I will say is the IEE wiring regulations 411-02-06 (ii) states: "SELV circuit conductors shall be enclosed in an insulating sheath additional to their basic insulation." that excludes bell wire as that is only got basic insulation, but alarm cable is fine because that's what it is intended for.
