Do breakers as they get old start to leak current?

I wanted to replace an outlet, turned breaker off, tic tracer went off, checked with meter, 2 volts, Why?

Because you are most likely using a high impedance digital volt meter.

This is referred to as “phantom voltage”.

Here is a NEMA article on it.
