Sprinkler Piping for Grounding Electrode

[RICK NAPIER]

Essentially by not allowing it to be used as an electrode and still requiring bonding it makes the electrician look to other sources for required electrodes. This also leaves the sprinkler installer free to modify the system including dielectric fittings.

Yes ago I had an inspector tell me I had to bond the gas pipe. I changed the service at the house and bonded the gas line. I got my butt chewed out by the gas company. I had to have a session between the inspector and the gas company so they could work out their differences. The gas company won. Now they use dielectric fittings.

I know 250.52 requires all metal underground water pipe in contact with the earth for 10' or more to be used as an electrode but I believe the fire code trumps that- not sure how or why but I would not bond on the load side of a dielectric fitting if it exist. Not sure what to do if it doesn't exist.

Oh, to have been there.
