I was working last night on an electrical circuit that was shut off at
the breaker.

Nevertheless, the voltage from neutral to ground and from hot to
ground both measured about 30V. This was enough to cause my voltage
probe to buzz and to even cause a compact flourescent to light
dimly. The current across the circuit however measure just 0.7 mA.

Am I correct in assuming that this is probably just induced voltage
from neighboring wires that run alongside it or is there potentially
something more serious and sinister going on?

Thanks!

SQLit did bring up a good point. A floating neutral could be a
possibility. Try putting a small load on the circuit and that 30V should
drop to almost zero. It it holds at about 30, then you have a potentially
dangerous wiring problem. However your measurement of 0.7 ma would tend to
rule the neutral problem out.
