Incoming supply on our job comes into the building and then the tails from which go into a switched isolator with 200A fuses fitted.
No idea what size the incoming fuses are or incoming conductor sizes. Would have to contact the DNO but not sure whether they would give that info to anyone or...
thought so but then I suppose if TTing it, fault protection will have to be put in place otherwise disconnection times wouldn’t be met so that’s another thing, would you rely on the low reading and not add RCDs or can it not be relied on as it can’t be verified as to what it is?
never had a situation like this before so would the best bet be to leave the earth connected as we don’t know what it’s for and add in an earth rod to ensure we are always reliably connected to earth from a known source?
Sorry 0.41 was with the tester clamped onto the 10mm earth only.
Could this earth go to another water/gas pipe elsewhere perhaps? Would you normally get such a low reading from a service pipe?
Shop with no earth coming from head, overhead lines in sight everywhere - definitely no earth from the DNO.
Two 10mm earths going into the DB. One going to the water and another which disappears through a wall somewhere heading towards an external area never to be seen again.
Customer doesn’t...
Plus a few seconds for the cable tie! Plus an extra 10 seconds when you realise you’ve had the cable tie upside down and they don’t work like that so you’ve got to take it back out and put it in again…
Regularly find myself sitting on the toilet looking through this forum. Whether I’m sat on the toilet now or not, I’ll leave that to your imagination…
Just wondering if there’s an iPhone app for the regs that I would be able to read instead of/as well as being on here?
