Engine Wiring Loom Ampage

[Chris Hebden]

I am about to buy some wire to start making my engine loom, but what ampage raiting should i get?

Also would this http://trigger-wheels.com/store/index1.html (wiring and accessories, deluxe engine loom), do the job?

Cheers

1mm Tri rated should be fine for 90% of it there are a few bigger ones like to the alternator but there prob 4mm or 6mm need to look at your old and measure them

[Chris Hebden]

I have, see http://www.rtoc.org/files/Technical%20Files/Chris%20Hebden/Main%20Engine%20Loom%20Harness%20Details.xls

As you can see the outer dia. varies a bit but how does that relate to the amps now?

[IANMM]

well the thicker the diameter the more copper is in it so the more amps it can carry hence why 6mm thick cable can carry more amps then 1mm cable

[Chris Hebden]

So back to my original question, what ampage should i be looking for?

http://www.autoelectricsupplies.co.uk/product/70 shows a 1.6mm wire being able to accept 11amps, is this going to be enough for the smaller wires?

[IANMM]

yeah thats fine mate

[Chris Hebden]

Nice one, thank you! For the thicker wires i am going to get wires to suit. So presumably the ready made wiring loom will be fine for use?

[IANMM]

yeah the 5mm wire should be fine in the kit
