Good Afternoon All,
I have just completed a Periodic test on a house and have a question about the meter tails.
The house is 14 years old so has 25mm meter tails. The CU is in the garage and the meter box is around 7m away on an external wall as you'd expect. Looking at it, I imagine that the tails run from the garage, through the joists in the ceiling of the hall and downstairs WC, then drop down inside the wall and enter the meter box. Due to the fact that I can't actually see where they run, I can only assume they run through the joists with no mechanical protection and then drop down the wall in steel conduits to the meter box.
I know DNO now stipulate that if the meter tails are in excess of a 3m run then you should install an additional protective device at the nearest point to the supply inside of the customers premises. My question is, would the house fail on a periodic test due to this not being in place?
Thanks in Advance, JT
