Circuit numbering
1 Circuit numbers consist of three parts: the
circuit prefix, circuit number and circuit suffix.
The circuit prefix indicates the type of circuit.
The circuit number describes the function of
the circuit. The circuit suffix provides an
abbreviation for the number or may be used to
further define the function of this portion of the
circuit. It also may be used to indicate the final
end of the circuit, i.e., LS or limit sw.
