skauldy Posted December 23, 2015 Share Posted December 23, 2015 Guys what sq cable size would be a general fit all for electrical work on the defender. Spots will be LEDs and plan on wring heads on a relay, changing to LEDs when funds suit. Shane Quote Link to comment Share on other sites More sharing options...
Aragorn Posted December 24, 2015 Share Posted December 24, 2015 I dont think theres a one size fits all as many different parts use varying amounts of power, and using the biggest size for everything would make the whole thing a bit unweildy. Are you just adding accessories or rewiring the whole thing? As a rough guide 1.5mm will do about 15A, and 2.5mm will do 25ish (CSA * 10 gives you an idea, and usually underestimates a bit so errs on the side of caution) You'll probably get away with 1.5 for most things but it really depends what it is.

vulcan bomber Posted December 24, 2015 Share Posted December 24, 2015 Standard cable in a loom 7amps per Sq mm, 8 if it's on its own. Thin wall cable will take a bit more because the insulation Is better. VWP's website lists what cable will do what. Quote Link to comment Share on other sites More sharing options...
western Posted December 24, 2015 Share Posted December 24, 2015 So do Autosparks Quote Link to comment Share on other sites More sharing options...
skauldy Posted December 24, 2015 Author Share Posted December 24, 2015 Yep plan on re wiring the whole thing. Someone recommended 2.5sq and as you say I thought it would be a bit awkward fitting it, 1.5 would be nice to work with. heard of the thin wall cable. Will check out that site. Thanks guys.

PaulMc Posted December 24, 2015 Share Posted December 24, 2015 If you use the Wiring Diagrams from RAVE as a reference, the wire gauges and colours are shown for all of the vehicle's wiring. What age is your Defender? . Quote Link to comment Share on other sites More sharing options...

What age is your Defender? . That's a good idea Paul. It started out as an 89 when it left the factory. The only original part left is the registration plate.

skauldy Posted December 24, 2015 Author Share Posted December 24, 2015 It's been a while since I served my time and no longer in the trade- mini disclaimer. When selecting cable am I looked at the sq or the amp rating of the cable. I would imagine myself the amp rating but in on the RS site and notice while that lets say the amp rating is 6A the sq of the cable varies from .25mm to 1mm sq. why is this.

That sounds a bit like my 1989 110 If you use the 300Tdi wiring diagrams as a reference - the wiring is still fairly basic, and should easily translate to a 1989 vehicle..

I would imagine myself the amp rating but in on the RS site and notice while that lets say the amp rating is 6A the sq of the cable varies from .25mm to 1mm sq. why is this. A cable's current rating depends on the type of insulation, as well as the thickness of copper. I wouldn't buy Automotive cable from RS - as, they only stock a very limited range of expensive cable from TE Connectivity. As previous posters have said, have a look at - VWP, Autosparks, as well as - AES, Polevolt, and Kojaycat. http://www.vehicle-wiring-products.eu/section.php/198/1/single-core-pvc-thin-wall-cable http://www.autosparks.co.uk/electrical-components/cables/thin-wall.html http://www.autoelectricsupplies.co.uk/product/70/category/114 http://www.polevolt.co.uk/acatalog/Thinwall_cable_cut_to_length.html http://www.polevolt.co.uk/acatalog/Full_100_mtr_Reels.html http://kojaycat.co.uk/epages/950000457.sf/en_GB/?ObjectPath=/Shops/950000457/Categories/Cable .

skauldy Posted December 24, 2015 Author Share Posted December 24, 2015 I should have just bought a chassis and log book. The only thing I would be getting the cable from RS more or less for nothing. Auto sparks are pretty cheap. I'll have a look at the others Quote Link to comment Share on other sites More sharing options...
