PME earth intalation

OK. A good electrician (and I shall stick my neck out here) should not tamper with a cutout.

Neither should a good consumer ;)

Attempting a PME conversion yourself :rolleyes:

Sorry :)

Just to clarify, supply was already TNC-S, longer tails were needed, somhow ended up with 25mm gre/yell instead of 16!

{EDIT] - For PME (TNC-S), neutral up to 35mm2 then a 10mm2 main equipotential bonding conductor will suffice as long as R<50/Ia

Isn't the size of the MEB determined by the CSA of the incomming neutral conductor, and a supply which has a neutral with a CSA of 35.0mm² or less only requires 10.0mm² MEBs :?:

(Reg 547-02-01 in the yellow regs)
 
If a 25mm main earthing conductor was required then you're looking at 16mm main equipotential bonding conductors.

It wasn't required, 16mm was required, 25mm was all there was available :)

Yes, was in the process of the edit above but you posted in between :oops:

It's late and it's been a LONG day!
 
Yeah (table 54H?), though for PME the DNO should be consulted prior to installation as they may have additional requirements.
