Re: Suplemental electrode conductor
rasmith: I agree. The size of the ground electrode conductor, at the panel, should be the largest size required, according to the available electrodes.
This was the original reason for the 5 foot rule on the water pipe. This 5 foot was to serve as a bonding bus for the ground electrode system.
The reason,on record,for the 5 foot limitation is stated as being a precaution for maintaining continuity in the piping system.
Using the real reason, for justification, would be
ruled a design issue and be rejected. The so called safety issue of the possibility of replacing the interior pipe with plastic, is a bit far fetched.
When has there been a code rule based on speculation? This is called "card reading" or "crystal ball gazing", in the real world.
