Ground Wire at Gas Line

Hello,

I noticed the other day that there is a shielded wire (not sure of the gauge) next to the gas meter at the side of my house. It doesn't appear to be attached to the gas pipe going into the ground, just wrapped around it? so I have somw questions.

It is a ground wire no?
It should be connected to the gas line?
where will I find the other end of the wire?
is this what they call bonding?

any help is appreciated,
GXM

No, that is a tracer wire that runs alongside the plastic gas line. When you have the utilities marked for underground digging, they can hook a meter up to that wire and trace the exact path of the gas line underground so it can be avoided by excavators.

Can I jump in and ask if the gas line/meter should be grounded to the electrical panel or a ground rod?

It depends on your local code and enforcement. Some places require bonding the gas line, other places forbid it.

If your area strictly follows NEC, the gas line should be bonded to the panel ground bar just like copper plumbing; however unlike plumbing, it should never be used as a grounding electrode (rod).

Some places believe that the ground connection through the furnace circuit is sufficient to ground and bond the gas line.
