I had a service call at a residence with an old 100 amp service. Both the POCO and CATV company were there prior to me getting there and left the service as is and told the HO to have her service upgraded. Upon my arrival I noticed that the service drop for the CATV had melted. The HO was told that their phones and internet would not work because the amperage on the ground at the CATV drop was greater than 1 amp (I've discussed this some time ago in a previous post). When I clipped on my amp probe there was actually almost 5 amps on the ground wire. I ran a temporary new ground wire and bonded it to the ground bar at the breaker panel. At the moment it seemed to reduce the amperage at the CATV D-mark by about 2 amps. Suddenly, the freezer in the basement kicked on and all the lights went dim. A few seconds later they got real bright. I got out my meter and measured the voltage at the breaker panel. There was about 78 volts on one hot leg and about 186 volts on the other. At that point I shut the main breaker but I was too late. The over-voltage burnt up the computer, CATV box and melted the CATV wire at the D-mark.
When the POCO originally came out to the house the HO said they checked their connections at the mid-span and at the point of attachment to the house. They never cut the tag on the meter enclosure or opened it to check inside. Their position is that the equipment attached to the house is the responsibility of the HO. As far as I'm concerned, by not inspecting the inside of the meter enclosure and leaving the customer with a obvious and potentially dangerous situation is irresponsible on their part. If you look at the attached photo you can clearly see that the service drop neutral is detached from the neutral in the meter enclosure. I think the HO should fight this and try to get compensated from the POCO. Any thoughts ?
