I've learned that 'experts' know little. Years ago I called a cell company to ask about the number of Meg Pizels on several phones. The guy instructed this engineer that MP has nothing to do with resolution.
I have a better one. I had just gotten into X-10 devices. (Where you can use a remote to turn lights, devices and dim/brighten lights, etc. I bought my first light switch replacement module. It had two different color wires and I don't know if it mattered which went to the 'hot' wire and which went to neutral.
I was told to wire one wire to black and the other to white! I told him that he was confused as if you did that and closed the switch, you will short the circuit out. I explained that he was confusing wiring an outlet with a switch. Meh told me I was wrong.
I told him I was an engineer working for an electrical utility, with decades of experience. He stated that I was wrong! I told him to walk down to the bookstore, in the mall and just glance through a basic wiring book. He refused to believe that he was wrong. This was my first interaction with him. He was above reading a book and I later, heard him giving everyone incorrect advice.
So, because one works in a Radio Shack, RC Hobby store, Cell phone company, etc., doesn't mean they know what the heck they are talking about!
