When we had our electric service upgraded, the electrician (as
expected) ran a ground wire from the cold water main inlet to the
ground on the panel.

I read somewhere that one should also run a similar grounding wire to
the natural gas pipe inlet but the electrician didn't do that.
- Is it required by code?
- Is it recommended?
- Should one use the same gauge wire as for the water pipe?
- Any special considerations?
- Can I daisy chain it from the water pipe or do I need to run a
separate ground back to the panel?

Thanks

The correct term is "Bonded". The current code as written requires that all
interior metal piping be bonded together. This can be accomplished by using
#6 copper wire and approved clamps. It is common in New Jersey to bond the
hot and cold water pipes together at the water heater location. It would be
very easy to continue the bonding wire to the gas pipe at the water heater.
Some jurisdictions do not require that the gas pipe also be bonded. Some
gas companies do not want their pipes bonded. The electrical inspector would
have noticed this and would have failed the job if it wasn't done correctly.

Did the electrician also install at least one (Preferably two) ground rod?
ive found most inspectorsdo not enforce this code here and some are
requiring only one ground rod we still use two but ground rods are
nearly worthless,certain conditions dont matter how many you drive down
you still dont get the 25 or less ohms to ground
