Why generator interlock kit installation comes up in Miami

A portable generator connected through an outdoor inlet and a breaker interlock is the most affordable way many Miami homeowners keep the refrigerator, fans, lights and a window AC unit running after a hurricane. The interlock prevents back-feeding FPL's lines, protecting line crews during restoration. The generator must run outdoors, away from windows and doors, since carbon monoxide poisonings rise after every major storm.

In condos, generators are usually not allowed. Permits come from the City of Miami's Building Department or Miami-Dade County. Ask for the circuits it can carry to be labeled.

  • Options range from a portable-generator inlet with an interlock to a standby generator with an automatic transfer switch.

Do I need a permit for generator interlock kit installation in Miami?

Usually, yes. Permits come from the City of Miami or, in unincorporated areas, Miami-Dade County; other cities in the county have their own building departments. The electrician normally pulls the permit and schedules the inspection.

Is the utility involved in Miami?

If the work affects the meter or service, the electrician coordinates with Florida Power & Light (FPL), which owns the meter and service drop.

Is an interlock kit legal?

Yes, when it is listed for your panel and installed with a permit; it is a recognized way to prevent backfeeding.

Interlock kit or transfer switch?

An interlock uses your existing panel and lets you pick circuits; a transfer switch has dedicated circuits or switches automatically with a standby generator.
