Scenario encountered:
New submain looks to have been taken from a PME supply in 4c 10mm SWA with no copper earth to a external metal feeder pillar.
The SWA has been glanded into new metal clad DB within the feeder pillar effectively incorporating it into the PME supply. A Earth has also been taken from the banjo to a earth rod within the feeder pillar.
The feeder pillar is intended to go on to feed a metal fabricated building with sub circuits and that’s what we have potentially come in to carry out.
Issues I can see but may be barking up wrong tree:
For me surely it would have been better to isolate the PME and TT this DB and all of its sub circuits?
As there is no internal copper earth in the SWA - PME hasn’t effectively been exported at all so bonds are currently ineffective?
