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



Only qualified allow qualified personnel work on electrical systems,
and follow all construction codes.


IMHO:

1. Required per 2005 NEC 250.104(B)
2. Required.
3. Per 250.104(b) use 250.122 as source of size.
4. Nothing special, but ensure you follow the NEC and local codes.
Give your local code enforcement inspector a call.
5. 250.104(B) tells you the options you have to bonding the metal
piping to. One includes bonding to the grouding electrode. If your
water pipe meets the requirements of 250.52(A)(1), then it is a
grounding electrode. So a water inlet piping can be used per code.

Now all this is using the NEC, and guessing about your local setup.
Only a qualified person working on site can help you. So this is not
a how-to, but a starting point for planning your operation. Research
with your local inspector, or AHJ.
