After a recent storm, the CATV drop to a customers house was replaced. Customer told me the installer did not hook up the required bonding conductor (shield to GEC) because it arced when he touched it to the grounding electrode conductor.
I stopped by this morning, no arc or spark when I touched the jumper to the GEC. Voltage measurement from shield to GEC varied from .5 volts to 1.1 volts as I had the customer turn on lights in the house. I suspect this reading is the voltage drop in the neutral. House is connect to transformer by about 100 feet of triplex & single conductor and there are four other houses on the same transformer.
I measured my own house & had about .3 volts, but I'm the only load on the transformer and have a very short drop.
Are the readings reasonable or is further investigation needed?
