How to identify breaker for a currently dead circuit?
The circuit has two GFCI outlets on it; both are unpowered and the TEST buttons have no effect (I've tried RESET, of course). The circuit also has an overhead fluorescent panel, and an outside security light, neither of which are working.
I thought I could use a circuit tracer (a.k.a. breaker finder) for this, but what I've read so far indicates that they only work on active lines (i.e., so you know which breaker to turn off).
Does anyone have a non-obvious suggestion for how I can find where this circuit is turned off? Or could I use a circuit tracer for this, even though it's unpowered?
