Hi,
I bought a house last year and this is the electricity meter/CU set-up in the garage :
The house was built in 1972 and I've so far been unable to locate where the supply is earthed. All the house circuits exit the CU at the rear and disppear into the wall, but there is no obvious earthing point to any nearby supply pipe.
Mains water enters the house in the downstairs toilet through a plastic pipe so there is no bonding there. The gas meter is on the opposite wall to the CU in the garage and there is no obvious earthing connection to that either, unless it's buried in the concrete floor.
I've even looked under the suspended floor of the room the CU backs on to and there are no cables beneath, so the only possible route would be down in the wall cavity.
Does anyone have an explanation as to what's going on, or am I missing something obvious ?
Would it be normal for a house of this age to have a hidden main earth connection within a cavity wall ?
Thanks in advance for any help or advice.
