[Heathkit] Gadzooks, when is a ground a ground?

[Larry Babb]

While all of this seems correct, my input is that these grounds do not take
the place of the neutral wire.
If the 220V is used to derive two separate 110 volt lines, the neutral needs
to be carried with the 220 volt line.
The Ground is separate.  The grounds will be connected to a common point,
usually at the service entrance panel,
it would scare me to wire a house without the neutral being carried in
addition to the ground.  If the integrity
of the neutral is compromised, the 110 volt lines can measure a lot
different than what is expected. 

Just my opinion.  Thanks

Although it used to be standard in the NFPA National Electrical Code to use
a cold water pipe for a ground that is no longer accepted in the NEC.  This
is due to the fact that today PVC pipe is often used and since PVC is an
insulator a ground is not provided.

NFPA NEC now calls for a driven ground rod at the entrance point to the
structure.

When I did some rewiring (with proper permits) I was told that I had to have
a COLD WATER PIPE ground. 
They wanted heavy copper wire to the pipe which was a long way away from the
service entrance. 
 
I ended up doing some trenching and putting in some extra hose bibs and
running the cold water pipe by the service panel.
 
Much cheaper.  They would NOT accept a ground rod of any sort.
