Here is what I got....
I got a call to go check connections in a panel and make sure it was safe. This is what I found when I got there.... it is a one story office building with five tenant spaces. Originally there was a meter socket enclosure with a panel nippled off of in each space. They ended up eliminating the meter at each space and installed switch gear on the back of the building with the meters in it.
Here is how they eliminated the meter socket enclose... They pulled the meter out. The poco or someone else slugged the three hot wires and left the neutral lugs the way they were. And put a blank cover over it, with the meter socket guts still obviously in.
So then I realized that the neutral lug/s are still bonded to the meter enclosure, which is bonded to the 1 1/2'' EMT that runs about a 100' back to the switch gear.
My questions are
1) Is this Legal? ( I'm pretty sure its not)
2) With the neutral being bonded to the old meter enclose and the EMT, and the building steel... Would there be any return current traveling on that 1 1/2'' EMT? Just a little bit even? Or would all the current be traveling on the just the neutral wire? Could not get my clamp on around it.
Thanks.
