This is for breaker location finding, not breaker diagnostics.
Yes, assuming no subpanels indoors. It will detect the closest breaker that powers the branch circuit.
The 110v plug device gets its signal generating power from the outlet, so that won''t work with the power off, but other batter powered signal injectors would.
Though not unlimited, it is unlikely your cable run is going to be too long to hear the signal at the nearest (first) breaker.

No. This is designed to inject audible noise onto a circuit for breaker switch location. Its not a diagnostic tool.
