In a pre-wired installation, when should the wiring be installed?

• A. Before the drywall
• B. After the drywall
• C. During the drywall
• D. After painting

Answer: (A)

Wiring is placed during the rough-in stage, when the framing is open and the walls are not yet covered. Doing it before the drywall goes up lets cables be routed through studs, into electrical boxes, and positioned at the correct depths with proper clearances. This keeps wiring protected, makes it easier to install outlets and switches flush with the wall, and meets code requirements. If you wait until after the drywall or after painting, you'd have to cut into finished surfaces to run or pull wires, which is destructive and far more labor-intensive. So, the wiring should be installed before the drywall.
