During rough-in, what should you verify with scale measurements from the drawings?

• A. Converted real-world dimensions and verify offsets and clearances.
• B. That the building's structural plan is identical.
• C. The color coding of wires.
• D. That the panel schedule is up to date.

Answer: (C)

Translating scaled drawings into real-world placement is what you verify during rough-in. You use the scale on the drawings to convert each dimension into actual spacing in the building, then check that the locations of boxes, outlets, and conduits line up with features in the field. This includes confirming offsets from walls, studs, corners, doors, and other structural elements, as well as ensuring there’s the required clearance around boxes and between runs to accommodate wiring, devices, and future access. That process—converting dimensions and confirming the proper offsets and clearances—is exactly what scale measurements are for. Color coding of wires is a labeling convention, not something you verify by measuring distances on the drawings. Verifying that the structural plan matches or that the panel schedule is up to date involves other checks (documentation and design coordination) rather than the on-site placement work you do with rough-in measurements.
