landy V8 Posted November 22, 2011 Share Posted November 22, 2011 hi all, i can get hold of some 60sqmm cable which i thought would be good enough for the wiring i'm doing for my challenge truck.i'll be running 2 x 8274 (standard at mo). this is only going to cost me £3 per metre. so before i go ahead and buy some i thought i'd ask your thoughts. many thanks Ralph Quote Link to comment Share on other sites More sharing options...
Mark Posted November 22, 2011 Share Posted November 22, 2011 We run 35mm^2 for each motor on our truck, so 60mm^2 is overkill - not that that's a bad thing. So long as it is decent multi-strand copper then go for it. Mark Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted November 22, 2011 Share Posted November 22, 2011 As Mark says yes - is this the very very fine super flexible welding earth cabling or hard very stuiff copper cabling - the stiff is NOT Good ! Nige Quote Link to comment Share on other sites More sharing options...
landy V8 Posted November 22, 2011 Author Share Posted November 22, 2011 it's fine strand flexible,60mm 415amp.they do many other sizes. looking around at what other people/places charge for cable i thought this was a bit of a bargain.

FridgeFreezer Posted November 22, 2011 Share Posted November 22, 2011 Bargain, only potential issues are stiffness, physical size, and weight. Can be a chore to work with big fat cables, route them around, terminate them, etc. Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted November 22, 2011 Share Posted November 22, 2011 I run 70mm2 multistrand and it gets warm to the touch on big long pulls. Quote Link to comment Share on other sites More sharing options...
landy V8 Posted November 22, 2011 Author Share Posted November 22, 2011 it's not that stiff really.it'll be easy to route the cable as it's bareish chassis,so the only confined wiring will be when i wire the batteries up. Quote Link to comment Share on other sites More sharing options...
Dave W Posted November 22, 2011 Share Posted November 22, 2011 Resistance (or lack of) is the important factor, especially so if you're running a 12v winch. Some welding cables have a large cross section BUT also have comparatively high resistance per metre so will reduce the available power of your winch. Remember a powered up winch under load is akin to a dead short across the battery, the only thing that limits the current is the capability of the battery to supply it and the resistance of the cables/connections to the motor.

simonr Posted November 22, 2011 Share Posted November 22, 2011 Naaa....70 is fine for a 'hobby winch' but if you were a serious 'extreme' off roader you'd be using at least 1000sqmm. It's only about 40mm diameter so easy to route - and it doubles as a roll cage! Just kidding - 70 is plenty! Si Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted November 22, 2011 Share Posted November 22, 2011 Si you could just electrically isolate each of the chassis main rails and use them instead of cable Quote Link to comment Share on other sites More sharing options...

dirtyninety Posted November 22, 2011 Share Posted November 22, 2011 im using 60mm^2 routing is fine, as is running a front 8274, my batterys are located at the back of the vehicle near the rear winch. Quote Link to comment Share on other sites More sharing options...
Tanuki Posted November 22, 2011 Share Posted November 22, 2011 When it comes to terminating it, you're gonna need access to a serious ratchet-crimp or hydraulic tool. --Tanuki. "Badgers are often the problem but never the answer". Quote Link to comment Share on other sites More sharing options...

landy V8 Posted November 22, 2011 Author Share Posted November 22, 2011 thats what i did with the last ones i made up.filled the terminal with solder then clamped it in the vice. Quote Link to comment Share on other sites More sharing options...
zardos Posted November 22, 2011 Share Posted November 22, 2011 Durite 0-703-80 crimp tool is worth every pen A snip at around £100 But if you are doing 2 x twin motor winches and a centre winch, isolators, extra batteries, etc it could work at a £1 a crimp just on one vehicle. Get together with a friend and do multiple vehicles and we are down to about 20p per crimp and getting cheaper all the time. It is also much quicker and less damaging to the insulation than soldering. Quote Link to comment Share on other sites More sharing options...

simonr Posted November 23, 2011 Share Posted November 23, 2011 Crimp then solder if you are going to solder! Solder has a higher resistance than copper so if you solder then crimp, you get a worse connection than crimping alone! Si Quote Link to comment Share on other sites More sharing options...
landy V8 Posted November 23, 2011 Author Share Posted November 23, 2011 Blimey Ralph, where are you getting that from? there is a trade electrical shop in Peterboro' that i used before when i needed to remake my battery cable on my Porsche 928.

Hmmm, might look in next time I’m up that way visiting family, need about 10m of the stuff, and not seen anything like as cheap available locally. What's the name of the place?

ejparrott Posted November 23, 2011 Share Posted November 23, 2011 @I bought something very similiar to this http://www.ebay.co.uk/itm/4mm-70mm-HYDRAULIC-CABLE-CRIMPING-TOOL-CRIMPER-/180612516845?pt=UK_BOI_Materials_Supplies_Electrical_ET&hash=item2a0d584bed a year or two ago, didnt expect it to do much good but, it came with a spare set of hyraulic seals, and has acctually done a lot of joints for various things. I think I paid less than this, but its certainly paid me back now! I always bare the cable, smooth with flux, crimp in the fittings, and then solder afterwards - never had any trouble that way. oh yes, although an awful lot easier than using a hand tool, i find i need to clamp the fixed handle in the bench vice to be able to use it.

FridgeFreezer Posted November 23, 2011 Share Posted November 23, 2011 For a bargain crimper google Durite "070390", it's compatible with LR Special Tool #1. Quote Link to comment Share on other sites More sharing options...
