Folks,

I am a long time reader but have finally made the plunge to join your extremely informative group. As you can see from my name, I am more familiar with cameras and photography than electrical matters, but have done some electrical wiring around the house. Yes, I even pulled permits for the work and had it approved!

I have a very basic, but nagging question, however: Since most appliances and tools are A/C today, what is the real purpose of the wider prong that is supposed to meet with the Neutral connection in an electrical receptacle when it's plugged in. Along that same vein, what are the consequences of having the not/neutral reversed at the receptacle? Since the current alternates this doesn't make total sense to me, aside from the grounding issues at the main box. Could the tools be damaged some how, for instance?

Thanks for any insights!
