A couple of questions. Is it really dangerous to run a good quality 12ga. extension cord in and interior wall? I have a 12ga. ext. cord that I use for a air compressor, saws, shop lights (and other shop tools) that never even gets warm. I also have a cheap 14ga (I think) ext. cord that I use for my lawn edger and leaf blower that doesn't get hot or even warm. Wouldn't these pull more current than a TV.? My 50" plasma came with a cord that was about 6' long and I have it running thru the wall (about 4' is in the wall). It has been that way for about 5 years. Should I redo it so it isn't running in the wall? I didn't realize the TVís power cord was not rated to run in-wall. Anyway, if I need to redo this could I just not make an extension cord out of some 12ga romex that I have laying around. That would probably cost about $4 instead of $150.
