So maybe a missing neutral detection device would be a good plan. This picture was sent to me last night by my daughter-they had some tree work done, and went to church before the work was finished. They got a call that there had been an "incident", but all that was damaged was the internet cable and they would be back in the morning and their insurance would cover it. They are too far away for me to be onsite and help, but that might have been a good thing. When I saw this picture, grandpa was a little upset that someone left a hazard like this for his grandkids (and kids
) to be around. I told my daughter that with that level of understanding they had no business doing tree work!
They did not notice any lights dimming, etc-which leads me to believe their home was getting its neutral connection through metallic water pipes and/or gas lines connecting the homes on the neighborhood. I told them to shut off the main breaker and find somewhere else to stay for the night.
