Wiring
Fuses
Fuses should be rated at about 1.5 time the maximum current flow.
Wire Sizes
Please note:
Current rating of cable refers to the maximum current the insulation can safely handle.
The cable should be rated for 2-3 times the expected current flow.
Auto wire conductor size will vary considerably depending on manufacturer. Only the outside diameter of the insulation is defined.
