I was replacing a receptacle and was not able to figure out for hours why there was an open ground on the tester. I had to get new receptacles and when installed, it showed correct on the tester. Once mounted back into the wall, it showed open ground again. Turns out, the ground prong on the tester receded back and forth. :D [ATTACH]63401[/ATTACH]

Hi everyone - I'm in the planning stages of a rewire job to eliminate some K&T wiring in the 2nd floor rooms of my 1929 home. House is two story with basement, and attic space above the 2nd story. Once I rewire, the plan is to blow insulation into the attic - but obviously want to wait until the wiring is done. Second story has three kids bedrooms (elementary school age kids and younger) and a bathroom. My problem is - once the insulation is blown in there, I may never want to go in that attic again to pull wire. So I've been kicking around the idea of pulling RG6 for cable tv, Cat6 for ethernet, maybe even cat3 and put phone jacks? We don't use a landline - not sure if that's a waste or not. Kids don't have TV's now. The old Linksys 54g wireless router handles our Netflix and browsing needs now. 1000 ft of RG6 quad shielded is about $60, and 1000 ft of cat6 on Monoprice (supposedly well rated cable) is about $125 - figuring connectors/terminations/etc I'd be probably into it for about $250, and have extra supply to cover additional rooms. Again, I'm debating on whether a little more labor and expense would save a lot of headaches later. Should I bother?
