There's an easy fix for that if you have the cohones.. you can just brush the wire with the back of your hand.
I stand corrected, I did mean high impedance; thanks for catching that.

For those less brave, on the cheap you can create a dummy load. An electrical socket like this http://www.lowes.com/pd_71105-334-S1...cket$y=15$x=17 some insulated alligator clips and a light bulb, connect across the hot and the neutral before measuring for voltage. Make sure the bulb is not burned out if the light doesn't come on and you measure voltage between the hot and neutral.

Two of these can be connected in series to check for 240 vac.

As always, use extreme caution when working with potentially live circuits and wear the proper PPE including safety glasses.

Not if they are on the same hot leg. If you were to read 240V between the two blacks then connected them together you would have fireworks and tripped breakers.

Please read my previous posts!

They're probably Two circuits off the same leg. Or, you would have a big, loud BOOM and a 240v. trip!

Thanks.. So for now, I'll install a new outlet wired the same as before. Based on everyone's posts it sounds like some previous homeowner probably crossed into the circuit accidentally and lucked out by coincidentally being on the same hot leg. So, this sounds "safe", but should be corrected to prevent further problems or injuries resulting from someone being unaware of the crossed circuit. I'll get an electrician in to trace back the circuit. I try to only dabble with electrical circuits which are straight forward, with no surprises. And I'm not comfortable moving things around in a panel.

I'm assuming the person responsible is the same guy which painted the outlets shut. Seems logical.

This is further proof that tampering with electrical wiring (or Plumbing and Gas, for that matter) is not meant for people who "Think", or "Guess" that they know, as the original installer of that electrical "job". !
