went to do some work for a relative today,change CU and a few odds and ends in a small shop which they have just rented,the landlord is a distant relative of theirs and has said they can do what they want.Anyway I was doing a few tests and found that the Zs on a radial was 400 ohms,Disconnected earth bonds at CU and tried to do a Ze,tester went into lockout straight away,anyway tested phase to neutral at cutout and got 240v tested phase to earth and nothing,it was a PME system so something very wrong. Anyway puts a call in to networks and about 2 hours later a guy came out and I explained the problem,he opened up the service head to find that a link had not been fitted between the neutral and earth,this was from 20 years ago when the new cable was fitted.He was not happy and neither was I it proves that not only was it not tested by networks when it was fitted,but obviously it has never been tested since,if this isnt a good advert for regular I&T then I don't know what is.
