Too many mirrors David.

This reminds me of a house I moved in to in 1975 built in 1936. After a few years I decided to check the earth out as I noticed we had 2 overhead wires + and -. There was no earth system at all so I
Bought an earth rod and wired it to the fuse box accordingly.
Then the MEB came and wired the earth to neutral WTF. If that had never been brought in would they allow that now?
I think they also used to use a 12" square galvanized plate buried in the ground. I've just dug one up here, house built in 1934.

So was that 4 earth rods?

Let’s open an old thread.

looking fo4 a brief answer. Wishful thinking.

on a pme system having an earth rod as an addition is perfectly ok in my opinion.


im working for and under a new electrician at work.
we have had a distribution board fitted by outside contractors. They have earthed via a 16 mm earth conductor within the 3 phase SWA supplied from a PME system. They have also popped an earth rod in at the new distribution board. We are going to run feeds of this board for various stuff.

the new electrician wants to convert to TT or get rid of the earth rod As he thinks it’s wrong because of “potential differences” I disagree.

Am I wrong? I’m willing to accept this If I am,

but I know earth rods where proposed as additions in PME in the 18th. So I’m sure it’s OK.

If the rod is bonded to the distribution board earth then surely there can be no potential difference. Did he mention which two points he was thinking of the difference being across?

I agree with you and really can't see the problem here, but it will be interesting to hear other views.

Thanks for quick responce. My thoughts exactly. Just had to check in case I had got it wrong.


This new guy has much more experience with these types of systems than me or so he said at interview, coming from industrial and comercail instals, but I’m starting to suspect he’s been relying on others to design his jobs.

To be honest I'm no expert either.

Be interesting seeing what else he says.
