1.Loads of different classifications (class A, class B, etc.) should not be on the same fuse
2.Group loads according to power requirement (battery, ignition, IOD/Dark Current, etc
3.Evenly distribute loads to prevent overloading of individual OCPD (over-current protection devices
Define OCPD/Relay device types
Detemine OCPD/Relay device ratings
OCPD ratings are sized to the cumulative worst-case load. Rating is chosen to ensure inrush currents will not fatigue the fuse, and assumes device derating due to thermal ;
