Discussion and questions related to the course Motorsport Wiring Fundamentals
Just looking over the AWG chart provided and comparing this with Narva cable sizing and ratings and am just wondering why there's such a big difference between the two?
Is it just marketing or does narva 5mm - 2.9mm² cable actually handle 25 amps? Referencing this chart suggests it would generally handle less than 16 amps?
I imagine the Narva rating is a best case scenario, as in a single conductor in 15°C ambient air temp for a very short distance. To my knowledge Narva only use PVC insulation, if so, the 25A rating is very optimistic and I would steer clear of using it for any vehicle wiring, most definitely any engine bay wiring.
