In plan drawings, surface-mounted wires are represented by which dashed lines?

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

Answer: (B)

Line conventions on plan drawings use different dash patterns to show where a feature lies relative to surfaces. Surface-mounted wiring is depicted with short dashes along the path, which clearly signals that the wires run on the surface rather than inside walls or concealed spaces. This short-dash pattern stands in contrast to long dashes typically used for hidden lines behind surfaces, and to dotted lines that convey other meanings such as centerlines or proposed features. Thick lines usually indicate major elements like walls or structural features, not electrical routing. So the short dash pattern is the correct way to represent surface-mounted wiring.
