Got Shocked

[kwired]

Bill that is a Wago that is connecting the three green EGC's, the white wire actually passes behind it, but notice the white wire from the MC cable to the right, it is striped out like it was landed, it's not bent and since all the other wires in the receptacle are back stabbed to me it makes sense that it might have also been backed stabbed but fell out as the receptacle was removed???

Of course it's just a guess?

Maybe the OP will give us some more info?

And OP did not necessarily tell us why he was taking this apart when he was shocked. Just a guess - maybe as part of investigation of why the load on the other end of that white wire wasn't working? If so he found the problem he was looking for - just kind of "the hard way".

Hello everyone,
I work at a University in NYC


I got shocked removing a cover off a prewired wiremold receptacle raceway.
As a result of my peers, on using the EGC as a grounded conductor.
I explained this issue to my director, the answer I got was "I am at fault for not test the enclosure first."
In the twenty years, I have never test any enclosure first.
I told my director it could have been a student who got shocked.

Thanks,
I don't think I'm nuts

Everyone, thanks for your feedback they are great. But let me clarify this little better.
The pictures I posted shows the work that was done by two "A" Electrician, prior to myself being dispatched to the same location latter that afternoon.
Here are a few more pictures to the area in question that day.
And the two Electrician never got disciplined to my knowledge, for that dangerous work being done.

Thanks again

Bump...................
Going to let others reply before I do since I wasn't looking at all the pics the first time!

Holly crap!
And by the way aren't those automotive wire type splices I don't think they're listed for 120 volts.

Can't say I have used that particular one before but have used other similar self piercing connectors- they were rated for 600 volts.

They are handy to use in long continuous rows of fluorescent strip lights.

If the note said "Neutral Broke" then consider the white wire hanging out dead.
They reidentified the green EGC with White tape but I'd bet they didnt move the EGC in the Panel or Subpanel to the neutral bar.
Thus any load off of those circuits is energizing the normally "Non Current Carrying" parts of the system.
Any difference of potential from that point would give you a shock.

If they did happen to move the Green wire Reidentified as white to the Neutral bar in the panel, I'd have to think a little more on why he got shocked.

The reason the OP got shocked isn't because the grounding conductor was used as the neutral, but because the aluminum chassis no longer has any ground connection. The chassis is free to float to any voltage, and either through capacitive/inductive coupling or direct contact, it is maintaining a non-zero voltage.

If the Jacket of the MC cable maintains continuity all the way back to the panel through the boxes and conduit as it should , the aluminum chasis is not floating, it still should be grounded somewhat, regardless of whether or not the Green EGC inside of it is terminated or not.
