I had a bad connection at the weather head connection to municipal power. Voltage ranged from 100vac to 135vac. All the lights in my combination oven/microwave oven burned out and my electric water pump in my radiant heating system burned up. Power company fixed the weather head then told me to go pound salt on repair expense...said it's my responsibility "for a safe operating condition". Is it common practice these days to have this type of protection? Do today's building codes require such protection?
