PME earth intalation

[securespark]

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

Sorry

Thanks everyone!

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

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.

Sure is.

Nooooo Nooooooooo, 25mm was required for the main bonding from the cu
