I hate agreeing with people who are right (?), but MOtrucker points out something, I prefer to check my outlets I attach my wrist strap to before I work on my stuff. Granted a GFI outlet is nice but I check continuity between the ground hole (green) and the wide slot (white) or use one of my 1960's neon bulb cheapo plug checker between the small slot (black). Also check my phone jacks to make sure green/red are the primary. But then I'm no rocket surgeon.
