The distribution center contains 18 AM-type plug-in breaker positions. Each breaker position has two-hole
connection points, one for the breaker output and another one for the ground return bus. The breaker distribution
system has 4 breaker positions for the batteries and 14 breaker positions for the loads.

Load breakers require mid-trip AM plug-in breakers while battery breakers require series-trip AM plug-in breakers.
If there is no power to the rectifiers and only one battery circuit breaker, there will be no alarm when the circuit
breaker trips.
