On plans, wires that run on a surface (not within walls) are shown as which type of dashed lines?

• A. Dotted
• B. Long
• C. Short
• D. Heavy

Answer: (C)

Line style on plans shows whether a path is exposed or hidden. Wires that run on a surface are drawn with short dashes because that short-dash pattern signals that the wiring is on the exterior surface, not embedded in walls. Long dashes typically indicate concealed lines behind walls or in hidden spaces, while dotted lines and heavy lines convey different kinds of information (such as proposed items or major structural elements). So the short-dashed line is the clear, standard way to represent surface-mounted wiring on plans.
