I was glad to see a preponderance of answers to the effect 'if it's not safe - run, don't walk". In my area of rural NY State so called electricians are greedy to take on any, even unsafe work. Prior to retirement I had a rep for turning down unsafe jobs & got ribbed a lot. BUT - - - I turned 85 yesterday and while not rich, I ain't broke either. Best news is I'm still alive. While I would have walked away feeling bad (sad?) for the old lady, I would have sent an invoice along with a brief description in laymans terms of the non-electrical condition. Fortunately NY State now requires ALL work in Mobile homes to be done by specially licensed contractors who have to attend yearly training. Not just electricians but all trades repairing, installing, whatever, mobile homes. Not saying that New York is perfect (or even ideal) but the government here cares about occupants safety followed closely by safety to tradespeople. Stay well gang and keep turning out quality.
