Electricity: Ground?

[James Sissel]

Modern code requires an 8' ground rod driven below ground level AND an
connection to the water inlet within 6' of entrance (closer is better).  The
ground must be attached to a pipe that comes directly into the house (no
valve between the ground and pipe).  Each ground should be an independent
connection to the panel.  Some power companies (KCPL) require all ground
connections in the panel.  Others want it in the meter.  Some want both.

I believe that the modern code requires that the plumbing be "tied" to the 
independent ground.  On non-conductive plumbing, they may require ground 
connections at the plumbing where electrical appliances such as dishwasherd,

washing machines, etc. connect.
