The AWG system provides a standardised way to measure wire thickness and is widely used in North America whilst the metric system provides a more straightforward and universally recognised way to measure wire thickness.

In the automotive industry, electrical cables are often labeled using MM standard to denote their size. For instance, you might encounter cables labeled as 2.5mm, 3mm, 4mm, 5mm, or 6mm. However, it’s crucial to note that these measurements don’t directly correspond to the cable’s nominal conductor area in square millimetres (mm²).

Sometimes it can be challenging to get AWG gauged cable to fit in metric lugs. A handy tip is to use electrical tape to compress the wire strands, slide the lug on the end and slowly pull off the tape.

Just remember, choosing the right cable size is like finding the perfect pair of shoes – if they don’t fit, you’re in for some uncomfortable dancing, and in our case, a potential electrical meltdown.
