Dear Steve

Please see below:

Sq mm Rating in Amp
0.2 1.4
0.35 3.2
0.5 1.0
0.75 14.0
1.0 16.5
1.5 21.0
2.0 25.0
2.5 29.0
3.0 33.0
4.0 39.0
6.0 50.0
10.0 70.0
16.0 110.0
25.0 170.0
35.0 240.0

Depending on load: eg 1 headlight @ 55W dividethis by lowest expected
voltage (during cranking) eg 11.5~12v, which gives a figure of 4.8 amps on a
12 v vehicle so the wire required is 0.5sqmm.

If you are using more than one piece of equipment on a wire, just add them
up and do same as above. Adjust for 24V vehicles (min @ crank is ~20v).

As far as measuring a piece of string will be fine although we like to use a
piece of 7 core trailer cable which behaves more like a loom around corners
etc.

Hope this helps

Best regards

Ginny
