Off-topic (imagine that!), I can't resist a bit of showing-off, under the pretense of a public service announcement.
Don't trust these non-contact voltage testers, too much. They're pretty good for verifying that the power is off, but they can be fooled by induction. My workplace has an entire building where you'll see 30 volts, on any connections, because we have cables for 100 HP motors running in the same raceway as the signal cable for our bin radars. It's spooked more than one contractor, and you can waste a lot of time chasing "ghost voltage" because your "sniffer" gave you a false alarm.
It's even better when the government inspector waves his sniffer at a cable, and I have to spend half an hour up a ladder opening connection boxes to show him the wires are disconnected and capped.
