gas line bonding. Natural gas or Propane ?

[Stevenfyeager]

Some inspectors (there are many, each city and county has their own inspector) in IN say don't bond a propane gas line in a house, but bond a Natural gas line. Others say both types must be bonded. The other state I work in (KY) insists on not bonding any gas line. It's confusing. Any thoughts ? Thank you.

Most gas lines are bonded thru the equipment grounding conductor of the circuit that feeds the appliance or equipment. Csst needs special bonding otherwise we never bond any gas lines.

250.104(B)(B) Other Metal Piping. If installed in or attached to a buildingor structure, a metal piping system(s), including gas piping,
that is likely to become energized shall be bonded to any of the
following:
(1) Equipment grounding conductor for the circuit that is
likely to energize the piping system
(2) Service equipment enclosure
(3) Grounded conductor at the service
(4) Grounding electrode conductor, if of sufficient size
(5) One or more grounding electrodes used, if the grounding
electrode conductor or bonding jumper to the
grounding electrode is of sufficient size
The bonding conductor(s) or jumper(s) shall be sized in
accordance with Table 250.122, and equipment grounding
conductors shall be sized in accordance with Table 250.122
using the rating of the circuit that is likely to energize the
piping system(s). The points of attachment of the bonding
jumper(s) shall be accessible.

I agree with Dennis unless it's a certain brand of CSST no additional pipe bonding is required or needed.
