Is it still a Main Protective Bonding Conductor?

B. Gas decided to a. relocate a customers meter and b. connect it to the gas main in plastic. The old meter was removed leaving a stub of pipe with the MPBC still connected. My view is that this is now an earth rod, auxiliary to the distributor earthing conductor.. Another guy looked at it and said its still good for MPBC.
It's a PME supply with good Ze.
Settle a debate please....

I found the original redundant steel gas pipe that had fed my house. Didn’t take me long to weld a stud to it and connect it to the earth nest. I was on a TT supply back then.

Don’t ask me why. A steel gas pipe makes nearly always makes a better earth than the old lead water pipes.

At work I had 4 x 8” welded steel ducts laid under a double rail track and two heavy haulage roads about 200’ in length each. Each had a stud welded at each end. One end was connected to the substation MET the other end to the switch room transformer bays MET.
My philosophy is if it’s conductive and it’s in the ground, use it.

PS I’ve only worked on private MV networks so don’t start quoting BS7671.

Yes you did, and I was just repeating your advice. But some people just need to be told the same thing a couple of dozen times before they actually listen.
