auto cable sizes

To do what?????????????????????????????????? To be more specific.

As big as possible.

I find cable that measures 1mm across including the insulation is good to connect a battery.

With a cable this size I can run a torchlight all night without any problems with a cable about a metre long.

But I find when I have a big long 30 metre length of 1mm cable running into the tent, the light at the end is really dim. I wonder what is happening?

Then I thought I'd really give the 1mm cable a good workout and hooked up my mates NZ70 600CCA battery and jump started the diesel engine. OMG, there was a lot of smoke for a short time and I've destroyed my favourite cable. Oh dear. It's melted.

See Darryl R2 - thickness and length and knowing what you're trying to power make an awful lot of difference. Learning about Amps, Volts, Current, Voltage drop, cable length and resistance is fun, bit of a learning curve, but fun, and kinda important so you can use your torch or jump start your diesel.

Darryl ; I think you need to ask the question again with a lot more detail of what you want to do .......a lot of drunken sailor talk going on .... LOL

200mm Squared works well for me, bit heavy and costs a bit but not much voltage drop. :-)

Darryl,
Tycab is an Australian company who make great products and know their business. I have used their products many times but have no affiliation whatsoever.

Follow the link and download their cable brochure. It lists the specs for more cables than you are likely to ever want. If you know what you are about then the brochure will give the answer. If you don't then go talk to an auto electrician so you get good advice.
