🚫 Common Solar Permit Mistakes in Columbus

• Assuming permit approval = can turn system on — need utility PTO separately
• Incorrect labeling — NEC 690 requires specific labels on every disconnect, combiner box, and conduit
• Not accounting for utility interconnection timeline in project schedule (adds 2–8 weeks)
• Missing rapid shutdown requirement (NEC 690.12 — required in NEC 2017+ jurisdictions)

💡 Pro Tips from Contractors

• Start the utility interconnection application the same day you pull the permit — they run in parallel and interconnection often takes longer
• In cities using SolarAPP+, permit can be instant — check if your city uses it before assuming 1-2 week wait
• All disconnects, conduit, and combiner boxes require specific NEC 690 labels — prepare them before final inspection
• Rapid shutdown (NEC 690.12) is required in NEC 2017+ jurisdictions — verify your inverter supports it before installing
