Which inspections are typical for new electrical installations?

• A. Only a final inspection.
• B. Rough-in inspection and final inspection (sometimes intermediate inspections).
• C. No inspections are required.
• D. A weatherproofing inspection only.

Answer: (B)

Inspections during a new electrical installation are staged checks to verify safety and code compliance at the right times, including before walls are closed and after all work is completed. A rough-in inspection looks at wiring methods, box locations, conductor routing, supports, and required clearances to ensure everything is set up correctly before concealment. The final inspection checks that the entire system—wiring, devices, grounding and bonding, overcurrent protection, labeling, and overall installation—meets NEC and local codes. Some projects may also call for intermediate inspections at additional milestones, especially for complex or specialty systems. This staged approach is why choosing both rough-in and final inspections (with possible intermediates) is standard; relying only on a final inspection could miss problems caught earlier, while no inspections would leave critical safety issues unchecked. A weatherproofing inspection alone doesn’t address the broader electrical compliance and safety checks needed for a new installation.
