There is absolutely no way that anyone can convince me that anyone but a Licensed electrician should install an electric service to a house. Also I guess that lady wasn't so competent after all. I would call her lucky at best. Lucky the problem was found before she and her house fried! I get very angry when I see people with a book or a video on wiring and they think they are electricians. If it were only that easy! There are some things best left to pros. Wrirng is one of them.
