awg guide for car wiring looms

[whensparksfly]

is there a awg guide for car wiring looms rather than checking every item in the car with a meter.

Easier to use a universal wiring loom for what they cost

 

[whensparksfly]

what universal loom do you use

Hello Whensparksfly,

AWG is American and not used generally in this part of the world. Look at this link which is a good guide. http://www.vehicle-wiring-products.eu/section.php/200/1/single-core-pvc-cable

If it's for a road car, or one based off roadggoing parts, just use the fuse ratings to go off.

Auto fuses are usually doubled to allow for surge

It gives you a quick, easy answer to your wire capacity though, unless you're building an ultralight race loom - just size for more than the fuse.

are you going to use modern thinwire or conventional thick insulation, irradiated pvc, or not, how long is your longest run going to be, is the vehicle canbus or not, is it 6, 12, or 24v. all factors that affect the current carrying capacity of wiring

Its a old school Rally car I believe.

in that case, find a copy of race and rall car prep book by Allan stainforth, have a look at the loom sugestions, pick your colours, go to your nearest auto factors and get them to supply you with 0.5mm, 1mm, 2.5mm thinwire, this will cover most of your requirments, use 25mm for starter circuits (welding wire is good) .5mm will carry up to 10A, 1mm up to 16A, and 2.5mm up to 30A safely, this should suit most of your requirments, just remember, relays for heavy current draws, and switch the negative(ground) side of the circuit.......... the battery master takes care or anything else when off

I wonder how much that would come to ??? the universal wiring looms I stock are £119 for the basic 8 circuit kit or £139 for a 12 circuit kit, just saying

... and switch the negative(ground) side of the circuit.......... the battery master takes care or anything else when off

Why?, I've found a few Jap cars use that system but prefer switching +V myself.

sorry being sleeping its for a rally car would love to use lightweight wire im still weighing up my options as the car is not ready for the loom yet.langy loom is by far the easiest option
