Tech Tip
The nominal power consumption is 42 amps (Watts = Volts x Amps using 500 Watts and 12 volts as the inputs) . It has a surge capacity and it would be a shame to have the fuse blow because of a momentary surge, so I suggest 60 Amps would be a good figure to use. You then have to use wire that can carry at least 60 Amps. You can look that up in the Ampacity Tables
