Information that changes the scope
- The exact panel make and model, since a listed interlock kit is specific to it
- Whether a generic or universal bracket was proposed instead of a listed kit
- The portable generator's output and which circuits it needs to carry
- Whether a permit and inspection have been arranged
- Whether the property might move to a transfer switch or standby system later
When a generator interlock kit is the right choice
- A homeowner with a portable generator who wants a permanent, code-compliant hookup instead of running extension cords
- Comparing an interlock kit against a full automatic or manual transfer switch before buying either
- An existing interlock kit installed without a permit that needs to be evaluated or corrected
- A generator inlet and interlock added at the same time as other panel work
- Confirming whether a local inspector accepts an interlock kit for a specific project
What a clear estimate should address
The scope should confirm the panel's make and model, that the interlock kit is a listed part for that exact panel rather than a generic bracket, the generator inlet and its location, which breaker feeds the generator connection, and that a permit and inspection are included rather than assumed.
Safety boundary
Never run a portable generator into household wiring through a receptacle, a double-male cord, or any improvised connection. That practice can backfeed the utility line, endangering utility workers and neighbors, and it bypasses every protection a proper interlock or transfer switch provides.
