I have a question about a strange situation.
Customer has a utility street light (old Mercury-Vapor) on his corner outside his house. Within the last two months, he has noticed at night that this light will cycle off & restart every time the 110 volt motor on his oil-burner furnace starts up.
Which makes completely no sense at all. His furnace blower motor draws 35 amps on start-up, runs at 7 amps. Fed with a piece of 14-2 Romex with ground, back to the 200 amp service entrance breaker box.
The street light is fed from the overhead utility power that shares a xfmr with the customer's house. But, this light is in a string of four lights, none of the other lights are affected by this furnace motor.
Finally, the customer is noting radio interference at night in the home. I am assuming that it has to be the faulty street light.
This is not a crisis, but I would like to get it resolved. Have any of you ever seen a situation like this before?
