Subpanel - equipment ground feed wire not terminated

Hi all,

I recently bought a 1950's house in Southern California. It has been remodeled a couple of times and in 2010 had an electrical upgrade. I think the previous owner did most of the electrical work himself, and it shows, unfortunately. A lot of sloppy stuff that I won't go into here (not terribly dangerous, but just not great) - but I'm in the process of cleaning things up piece by piece.

Was looking at one of the two 90A subpanels in the house yesterday and verified that neutral bar is isolated from the panel and terminated properly to the feeder. The equipment ground bar is properly tied to the metal panel. However, what was odd was that the equipment ground feeder wire was not connected to anything - just left hanging in the panel (unstripped).

I went to the main panel and double checked everything there - everything looked good there - common neutral and equipment ground bar and the feeders for the subpanel in question were all connected properly. I also verified wire sizes and looks good.

My question - is there any reason why the equipment ground feed shouldn't be connected in the subpanel to the ground bar? Seems dangerous to me to have the ground potentially float (I did check the ground bar with voltmeter to make sure it didn't have any voltage relative to neutral or the equipment ground feeder - I suspect there was enough of a ground with some conduit somewhere).

No good reason !
How ever what could have been going on was
that they were having problems with GFCI's.
So they took the easy way out.
Not good practice !
but some DIY'ers will take the easiest way out.
