trobb, I would tell them to watch out for blinking lights, and for burning smells. If I remember right on the pictures above, the homeowner had a 30 amp breaker on the 14/3 romex that melted in the attic. Electricity is not a hobby in my opinion, it is a profession, not something to play around with. A person's life is worth more than the cost it would be to do something right, and I'm sure you agree. Give them my regards and I hope they stay safe.
