Anyone hiring you would be led to assume that you are a professional in your trade.
But I am a professional in my trade and as such I would only give proper advice that I KNOW is right.
I can see where a liability issue may come into play, but if I tell you to hook the green or bare wire to the green screw, the white wire to the silver screw and the black (or other color) wire to the brass screw then what is wrong with that. Or if I tell you your circuit is overloaded and needs to be upgraded or a new dedicated circuit ran. Where is the problem with that?
General knowledge for everyone here, but there may be a need for it in my local market place.
The Big box stores have guys that work in the Electrical dept. and give terrible info. Last year, I'm walking around one of these stores and overhear a conversation between a clerk and a lady customer. She was doing some "footwork" for her husband and evidently he was a DIY. She wanted to know if she could add any more circuits to their panel. They were re-doing their basement. She had a detailed list of the breakers in her panel and what was placed on each one. (Impressive to say the least}
Well the clerk looks at it right quick and adds them all up and says "You can't add anything else because you already have 385 amps and it's only a 200 amp panel" He then proceeded to tell her more garbage.
Anyway after he was done and she started to walk away I stopped her and explained that everything does not pull a constant load at all times and that her house is perfectly fine. I then told her it would probably be fine to add things to the open spaces, but to have someone check her panel with an ammeter before and after they were done.
Now this was FREE info I gave her. Nothing was received in return, but she had also just learned what she needed to know. Now if she had listened to the clerk, they would all still be confused.
I am going to see if there is a market for this type of information. If not, then so be it, but at least I can say I tried.
