MOST of the=20 outlets were 3 pin grounded type, but only hot and neutral connected.=20 There was no ground of any type, either by conduit or wired connection. Since we are within City limits, we had to hire a licensed electrician=20 to change all the outlets back to the two pin type. He did leave us with = a GFCI in the bathroom with _NO GROUND_ connection. I am now in the process of pulling all new electric as we remodel each room, making sure we are in compliance with current codes. I may not be a licensed electrician, but I am quite sure I can do better than what = was here when we moved in! Lyle -- http://www.piclist.com hint: The PICList is archived three different ways.
