The designation code breaks down into three different
parts: (1) circuit, (2) assembly designation, (3) system
designation (fig. 1-7).

circuits.
This index provides a way to locate a particular
circuit.
Examine the circuit index on sheet 1 of the hull
elementary wiring diagram (appendix A).
After examining the
index, you find it gives the name of the circuit, the sheet
number(s) where you find the circuit, and when applicable, the
bus that feeds the circuit.
Like the other indexes, it gives the assembly designation,
nomenclature, and the sheet number(s) where you find the
circuit breaker. This index also has a reference designation
(REF DESIG).

Using this designation and the other
information given in the index, you can locate any circuit
breaker used in a circuit on the wiring diagrams.
diagram and you are not sure what it controls, you can
return to circuit breaker index and use the designation
code to find the circuit it controls.
Furthermore, you
can use the assembly designation to determine which
assembly houses the circuit breaker.
