Wanted to ask this question before I got a spark in to quote for changing the consumer unit, stage one of a complete rewiring.
Just got the keys to a 1939 semi-detached house that has original wiring, only 6 (round pin) sockets in the house. The mains cable that enters the electric meter looks like it may be too small a gauge for modern power requirements of a 3 bed house. It also appears to be the wrong sort of cable and disappears off in the direction of the adjoining house, I need to lift more flooring this weekend to see where it actually goes.
The cable looks like 10 mm2 or possible 16 mm2 cores and it has a lead outer, the cables shape is that of the 2.5 mm2 lead outer twin & earth that is in other parts of the house, but just with 10 mm2 cores.
Back in the 1930’s sometimes did they run one supply cable from the road and share it between a pair of semi-detached houses, which is what I’m thinking may have happened in this house. As my supply cable doesn’t look robust enough to have been buried all the way from the road.
If the supply from the road has been shared between the houses (pre meter) can the same be done again with new cable, or would I have to pay for a new connection to the road supply.
