Electrical Rough-In Inspection Checklist
For: Electrical inspectors, EITs, GC supervisors, master electricians
Once drywall is up, every electrical violation costs 10× more to fix. This rough-in inspection covers the items inspectors actually fail jobs on — not just the obvious code references but the workmanship items (box fill, support spacing, derating) that determine whether the install will pass first time.
