[QUOTE="Will C, post: 550072, member: 37506"] Well I checked today and It’s actually 16mm2 (70amps) in the car right now hahah 😂Pretty sure that’s not rated enough for a battery cable, especially with a 100amp circuit breaker. Thank god the wiring was fine otherwise…. Don’t know what I was thinking back then……. madness. I touched the positive battery terminal today when I was at the car and the terminal was slightly warm (i did not have my 100amp circuit breaker installed today), this was ignition on engine off for about half hour while I was doing stuff with the laptop connected to it. Is this because cable only 16mm2 ? Anyone know why it would be slightly warm ? Either join two together for 51mm2 , not quite sure how i’m going to re-insulate to a high standard. Or just send back and buy 5 metres of 50mm2 cable for the same price… Think the latter, thanks all. [/QUOTE]
