Morning chaps,
A bit of background. Finished a job yesterday, it was a bathroom install for the council on a private job. So with these they are grant work for the disabled, existing installtion dated, we have to note this on the certificate and install new circuit off a small new board for our installation. Earthing and Bonding ok etc etc. My installation all Fine and conplies with the regs.
Before starting noted it was a TN-S system, phoned up told it was an 80A fuse etc etc.
Came to test the Ze, PFC, initial IRs at the end of the first fix. Open up the dated unsealed DNO head. Found a fused neutral, Ze reading of 6.63 Ohms. Phoned the DNO, within a hour someone had come and put a front end RCD on the whole installation then 2 Hours after that they were under next doors floor repairing the cable, new head fitted top job. New Ze of 0.24 Ohms.
Now, this house had had a hob fitted on a new circuit by a local NIC electrician 6 months ago, got hold of the certificate and he had got high Ze readings aswell. I asked the owner (90 year old lady) and she didnt know anything, however her daughter said the electrician told them there was a high reading they needed to sort, but gave them no contact details, info or anything. He left the house knowing the 3036 fuses in her main board (2 of which had 1.5 in them instead of fuse wire, which i replaced, when doing these grant jobs i alway make sure the existing fuse wires are atleast fused correctly) would not be under their maximum Zs readings(No RCD).
Which brings the question, i have always notified the DNO on behalf of the customer for anything not fit... Is it our responsibility or the owner of the house?
Cheers
