You should have seen the problems I had when I had the house
electricians wiring up an r-f shielded room. Trying to convince them
that they had to run just *one* ground wire from a single point on the
room to a building ground and not the service entrance ground *and*
that the wire couldn't be bare and laying on the sprinkler system
piping, the A/C ducts and electrical conduit in the overhead.

Then fighting off the fire department guys that insisted that they
were going to run a pipe into the room for sprinklers.

Apparently the electricians only knowledge of 'loop' was in 'loophole'.
