At my local Home Depot they have "Trade Experts" or something to that effect. The girl in the electrical department is a trade expert and pulls down over $65,000 a year. I know this because I dated her for a while. She's also an electrical contractor. I feel sorry for her, you should hear the stories she tells, every day dozens of DIY types are asking her about their crackpot ideas.
When she tells them their idea is a hazard or a code violation, they couldn't care less, they dismiss her and buy all the wrong stuff for their half baked electrical job.
