On plans - wires that run on a surface (not within walls) are shown as ______________ dashed lines on plans

• A. long
• B. short
• C. medium
• D. extra-short

Answer: (B)

Wiring on plans uses different line patterns to convey how the installation sits in reality. When cables run on the surface, they’re drawn with short dashed lines so it’s immediately clear they’re not inside walls or conduits. The short dash length is distinct enough to be readable on a crowded plan and to differentiate surface-mounted wiring from other placements, like concealed or interior routing. Using a longer or different dash pattern would blur with other symbols or fail to signal that the wiring is on the surface, so the convention is to use short dashes for this case.
