Electricity – made understandable

Starting to “build the electrical system”

A more simple electrical schematic

Electricity 28 volt system (1) 10 ampere battery –Located under nose baggage compartment floor (2) 75 amp belt driven alternators –(1) each Alternator Control Units –Regulate voltage, shut down alternator in the event it begins to produce excessive (32+) voltage, parallels the two alternators

Routing Power from battery continuously available to hot battery bus –Grd Clearance –Courtesy lights –Nose baggage compartment light

Routing - 2 Power available from battery through master switch, to the 80 amp circuit breaker on to the tie bus Tie Bus –2 Main buss circuit breakers –1 non-ess circuit breaker –2 avionics circuit breakers
