Evening all,
My first post here, hope you are all welcoming
I have my QS assessment coming up next week with the NIC.
Question is, I am going to a property where I installed a 2way board, split the tails, upgraded the bondings etc. Straight forward job but the resident has a 24 hour oxygen supply running from DB1. Lovely old lady, I didn't want to turn the power off for her when I did the works, I tested my new board (db2) but with all the earths connected in as mentioned above I didn't want to turn the power off. 0.13 ohms, TNc-s.. all good.
I am just wondering if I am not able to turn the power off on DB1, therefore not disconnect any main earths, will the NIC let me test the ZE as an 'operational limitation' or as a zDb with it being a domestic property?
I understand 0.13 may not be a true representative of the earth fault path with the parallel earths connected, just wondering what I will say to the inspector when he asks me to perform a Ze test??
Long winded I know, but if you was in my shoes on the day what would be the correct way of going about this?
Many thanks all
