The main diagram depicts the general layout of the system. The 2/0 AWG battery positive cable is connected to the
main positive distribution bus via a 300A post-mounted fuse and an isolation switch.
The inverter is connected to the positive distribution bus via a 250A class T fuse and an isolation switch. The class T
fuse block should be mounted as close as possible to the positive distribution bus. The inverter switch is required for
inverter isolation and inrush management when first turning on the system. The chassis DC grounding cable (green)
should be sized not less than one size smaller than the DC positive conductor and have a capacity such that the DC
positive fuse has an amperage rating not greater than 135% of the current rating of this ground wire.
If the positive cable supplying the inverter shorts to ground internally, then the chassis ground cable needs to be able
to carry enough current to blow the inverter fuse without melting and possibly causing a fire.
