Not sure which thread to start this, so I chose this one as most appropriate.
Model homes in a Tract, garage converted to a sales office. Home ran off generator for approximately 2-3 months. I do not know what type/amperage/condition of generator was used. They had power from the POCO installed approximately 8 months ago.
Tract sold out, now converting the sales office back into a garage. Took the panel cover off the house, and all of the bare ground wires, including the # 4 going to the ufffer, were blackened. You could rub it off, but not easily. It was also on the bare portions of the neutral conductors and the bare portions of the ungrounded conductors, more noticeable on the larger conductors (# 8 ungrounded conductors to the range breaker very noticeable).
The conductors were screwed tight on the terminals.
I know this is not much information, and I do not have Marc?s testers , so I am stumped.
I suspect a ground issue with the generator, but I cannot even find out about how/if it was grounded at the generator. I was not there when the generator was set or installed, and cannot located anyone who was.
All circuits seem to function properly, wiring is just ghoulishly blackened.
Any theories?
