[AMRadio] FW: 220 vac line

Mon Jul 25 11:57:44 EDT 2011

That would be at odds with the GFCIs installed in my house!

There is black for HOT, white for NEUTRAL, and *INDEED* bare for the 
ground pin of the *proper* three prong receptacles.

I'll add that I am in Virginia, AND when a contractor used a faulty 
electrical tool - The GFCI worked as it should have!
