Ok, before anyone else replies, YES I WAS BEING SARCASTIC ! When HD first opened here (it originated in Ga) it was a sort of haven that tradesman could go into just to go aaah and look at the tools, but now it's just another corporation that is just interested in the bottom line,profit. Don't get me wrong I still enjoy going in to look at the tools, but it seems that most of them are wearing orange vests now. So seriously, if any new HI's want to gain a better understanding of panels or just elec. in general, educate yourself as best as you can, read as much as you can, take as much advice as you can from the learned individuals that make up this forum, and don't be afraid to ask advice from experienced tradesmen both in residential and commercial electrical.
