Hello Alll,
I am semi retired these days and wiring a small barn I built last summer.
I have a temporary 30A 240V SOW cord running from the house to the barn for temporary power.
The house only has a 100A service, so the barn will have its own 200A service.
I was finishing up the panel inside and I looked at the bonding jumper and thought, well, this
will be service equipment so I might as well do it now.
The strange thing is, before I did this I had measured how much power I was drawing from the house.
I was drawing 12A on one side, for a small heater, and 3A on the other for work lights. The neutral showed
9A which seemed normal since it was the unbalanced current.
But after I installed the bonding jumper, it showed 6A on the neutral and 3A on the green ground wire of the SOW cord.
Why would this happen ? Is the neutral just searching for the easiest return path ?
