Automotive FLAT Twin 2 Core Cable 12v 24v Thin Wall Wire (42 AMP Rated 4.5mm² 11 AWG) 5/10/30/100 Metre (100 Metre Roll)

So, who knew, you can't just chuck any old wire into a 12v circuit! 🤦Had added some extra USB sockets into caravan, and had no end of issues with the not charging correctly and other things not working correctly when they were in use. Needless to say, the grade of wire I had previously used was inadequate. Ripped out, replaced with this as advised, and everything now works perfectly! Good quality cable, and does what you want it to do! Doesn't appear to leak electricity all over the floor of the caravan, so shall probably purchase some more when I decide to mess about with things again!

This is the one. I've bought cheaper wire off eBay and wasn't happy so I bought this and I could tell just by the weight of the package this is good quality.

Best price at time of purchase

Boating electric, I’ve purchased loads of this and will continue to do so for all my extra low voltage projects!

This high current cable is ideal for bringing power from portable solar panels to the storage batteries without significant losses.

I was using 2.5mm to supply my car heating, yes I have a heater for the engine & windscreen for the cold weather, also keeps battery charged. 2.5mm volt drop too high, worked magic, only used 8m the rest will be for my solar panels. Pity it is so expensive.I like this cause the inner cores are well coated in powder, easy stripping.

Nice quality, reasonably flexible and well insulated. It even conducts electricity!

Cable that works and seems to be as specified works fine with solar array and 30A charge current
