Can you use this to trace the outlet to its circuit breaker if the circuit breaker is damaged or off?

Unfortunately it can't. The CB 10 used to locate breakers from a energized outlet. The device needed to find a open, or deenergized circuit will have a tone generator built in, these are more commonly called wire tracers.They are a little more expensive but well worth the cost.

I have outlets wired in series: some NM. some metal-shielded. Can I detect signal in accessible wires "halfway" to the breaker to confirm route??

You should be able to trace wiring that is not in a shielded metal conduit. I submit however, that your outlets are not wired in series, they are in parallel and perhaps daisy chained, but they will not be in series, nothing will work if they are. Remember the old Christmas tree lights that if one was bad or missing they all went out? That was series wiring.

Can this trace a wire routing through the wall.

In answer to the question, the CB10 can not be used to trace a wire behind walls. There are instruments out there that are designed specifically to trace the location of hidden wires but are extremely expensive.

can it be used to test another outlet to see if it's using the same line/breaker?

Thank you for your most recent email inquiry. Model CB10 can be used to identify what breaker an outlet is on. Please contact us if you a have any further questions. Thanks. Best Regards, Westtown Products
