Team 1852:
The gold panel given in the kit is for 40 Amp fuses (needed for CIMs, for example) and the other panel in the kit is for 20 or 30 amp fuses. If you have the breaker panel shown
here, you don't need to use either of the panels given in the kit, because you can fit the 40A fuses and the 30/20 fuses, too!
