Came across some twin and earth that ive not seen before guys and was after some advice on whether its ok.
Its a TNCS supply with the tails coming from the meter into an old 60A switchfuse. From the sswitchfuse runs a twin and earth cable for about 20 metres to the Cu on the other side of the house. An earth cable (earthing conductor) runs from the service head up to the switchfuse where it is choc-blocked to the cpc of the twin and earth.
Now, the cores of the twin and earth look to be about 16mm but could it be an imperial size?
I would say the cores look like aluminium but they may be tinned copper i suppose, did they ever do aluminium twin and earth?
The cpc in the cable i would say looks a bit smaller than the live conductors, maybe only 10mm.
Im just trying to establish the cable type so i can work out if the 60A fuse is giving the protection it needs.
Sorry no photo's, i know how everyone likes them!
Thanks.
