Hi,
I've recently bought a two story house I am preparing to let out. The electrics generally test ok but the supply cables to the meter and distribution boards are a bit "light" and I'd appreciate any comment on possible improvements.
Existing - a good sized (modern looking) cable arriving at main fuse from supplier - main fuse 60A - 16mm tails to meter - two sets of cables leaving meter; 1st set 25mm tails going to consumer unit with 80A rcd (not split load) feeding el shower(32), el cooker(32), 3Xsocket circuits(2 rings)(32,32,16), lights(6), smoke alarms(6), combi boiler(6).
2nd cable leaving meter is 10mm t+e going upstairs to another consumer unit with 80A rcd (not split load) feeding shower(32), 2 socket circuits(rings)(32), lights(6), smoke alarms(6).
My conclusion is the 16mm tails to the meter are too small and the 10mm t+e is way too small.
My thoughts for improving it are to discuss with the electricity supply company getting the fuse uprated to 80A. Uprating the 16mm tails to the meter to 25mm, and uprate the 10mm t+e to the upstairs consumer unit to 25mm also (with a 16mm earth). (I know having everything on RCDs is not ideal but in time I will look at fitting split load units.)
Any thoughts or help would be appreciated, thanks.
