Just how much amperage is normal on the GEC?

[jar546]

Not so funny question. On a 600A service that fed 8 apartments and a house panel, is any current on the GEC outside the building considered normal? Would 1.2A be a concern?

In a perfect world you would expect all of the imbalance current to return on the neutral but since the neutral and GEC is tied together at the service, shouldn't we expect some current to return on the GEC?

I can't afford a ticket to Perfect World but there has to be some of this imbalanced current that is expected.

Thoughts?

This the why behind dielectric unions on gas pipe that’s buried.

This can cause metal gas pipe to corrode if there is no dialectic union..

Would this be considered stray electric?
