Do I Need a Permit for an Electrical Panel Upgrade? in Verenigde Staten
Electrical panel upgrades almost always require a permit in the US, Netherlands, and Spain. Polish work typically requires a notification (zgłoszenie) plus a qualified electrician's certification rather than a full building permit. Permits trigger inspection — work done without one fails home-sale inspections and may void insurance.

Country-specific detail
Every US state and most municipalities require an electrical permit for panel upgrades. The work must follow the National Electrical Code (NFPA 70). After installation, a city or county inspector verifies the work before the utility re-energizes the service. Some states allow homeowner-permit pulling for owner-occupied work; most require a licensed master electrician.
