Theory & DesignQuestion 89 of 110
A single-line (one-line) diagram represents an electrical system by:
a.One line for each circuit or set of conductors
b.Each individual conductor drawn separately
c.The physical layout of raceways
d.Only the branch-circuit wiring
Explanation
A one-line diagram uses a single line and standard symbols to represent circuits and equipment, simplifying analysis of the power system.
