Hi all
I am on a TN-C-S / PME supply and have an outside tap, I have fitted it with 5 speedfit plastic elbows and a speedfit all plastic valve. So having so much plastic in place that should be the recommended insulated section of pipe to prevent dangerous voltages being on the tap in the event of a PEN failure
With the pipes full of water the resistance between the MET and the outside tap is 1726 ohms, so I work that out to be a potential current of 133mA which is still enough to be potentially fatal?
Please correct me if I am wrong here?
I know people say the risk of a PEN fault is so low you don't worry about it, but if it never happened why all the regulations for EV charging from PME, also I live in a very windy little village with individual overhead cables from the transformer down the street and UK power networks are often out to repair them. Information from UK power networks would indicate there is an electrode at the transformer and 2 more down the road, it seems the nearest to my house is 8 poles away and some of those poles look as if they could fall down lol, so if its gonna to happen anywhere I guess it would be here.
Thanks Marcus
