Frequently asked questions
Do I need a permit to replace an electrical panel?
Yes, always. An electrical permit is required, a licensed electrical contractor must perform the work in most Florida jurisdictions, and the utility will not reconnect service until the final inspection passes.
How long does a panel upgrade take?
The physical work is usually one day with power off for 4-8 hours. Utility disconnect scheduling and inspection generally stretch the total to one to four weeks.
