I am currenty building a Vet Clinic.
The electrical inspector is concerned
about the large animals feeling a
electrical charge though the concrete
floor. He wants the floor grounded; at
this point it is impossible to do without
removing the floor and repouring a floor
that is grounded. The local building
inspector is not concerned about having
the floor grounded. I din’t think that
concrete was a good conductor of elecric
of any kind. I just can’t beleive it is
posible. Has anyone come across or
heard anything like this.

Jay, If your slab is sitting on the ground, it is grounded. I think your inspector has been smoking something....

FreddyL,
Can you spell cow manure.
The stray voltage is in the stanchions, water bowls and vacuum lines of the barn and the cows ground on the concrete. This problem is eliminated with proper gounding of the metal piping and putting the cows on rubber mats.

*Somewhat related, I know a guy who buried an energized wall outlet behind some mud work. Until they found the correct circuit, the owners were complaining of a slight tingle everytime they touched their countertop.
*Concrete in the ground IS presently the most widely accepted method of electrical grounding in new construction. This is called a UFER and is accomplished by turning up the bottom rebar to allow the connection of the system ground. The concrete-rebar assembly becomes the grounding electrode. To then say that concrete in the ground is not properly grounded is, to say the least, stupid.
*Jay,My wife is a Veterinarian and Gabe hits it right on the helmet. Properly grounding all metal surfaces and systems will be sufficient. Mike is also absolutely correct concrete in the ground IS grounded...if it hasn't been isolated by continuous insulation. Richard Max
