Bonding Plastic Water/Gas Lines?


If plastic water/gas lines are used by the plumber in residential construction, any copper stub outs for faucets and so forth (18" long or more) must be bonded with a #6 wire... correct?

We are starting to see more and more of the plastic lines in my area and I would like to get some input from other electrical contractors.

thanks

Incorrect....

250.104 Bonding of Piping Systems and Exposed Structural
Steel.
(A) Metal Water Piping.
The metal water piping system
shall be bonded as required in (1), (2), (3), or (4) of this
section. The bonding jumper(s) shall be installed in accordance
with 250.64(A), (B), and (E). The points of attachment
of the bonding jumper(s) shall be accessible.

(1) General.
Metal water piping system(s) installed in or
attached to a building or structure shall be bonded to the
service equipment enclosure, the grounded conductor at the
service, the grounding electrode conductor where of sufficient
size, or to the one or more grounding electrodes used.
The bonding jumper(s) shall be sized in accordance with...


Metallic fixture stubs are not metallic piping systems. There is nothing to be done, bonding wise, on such an installation.

All new houses here are built using PEX plastic tubing. Faster and easier for the plumbers to put in, but some of them tend to make a real mess of their runs behind the walls.

Some plumbers don't care, all they want is to turn a profit as fast as possible. The funny thing about it, pex can be installed quickly and can have a clean look, if one wants it to.
