Thank you for your input guys!
So I have a bunch of questions.
1. Most importantly, should I have the homeowner not use any power in the house until this is fixed?
2. Because this is before the meter, does that mean the Utility company must fix it at their expense?
3. Could this be a result of improper wiring within the house? ( I did discover strange things; outlets with black wires neutral and white wires hot, a 3-way switch that had a bare ground wire connected to one of the non-ground terminals, all of which made me think the wiring was poorly executed throughout)
And more for my personal understanding: If I understand the circuit detective article, which is doubtful but.... not all the amperage coming in through the black and red phases is going out the ground rod--would it only be the difference between what is being used on each phase? In other words, if the loads on each phase were perfectly balanced would no current need to go out the ground back to the source? Thanks for any help in knowledge and understanding!
