Hi All
I was just hoping someone could give me some advice on old installations (guessing 1950s and before) where a bare earth wire runs from point to point alongside normal 2 core cable.
I've come across this twice now. One time whilst ripping it out for a rewire.
I guess the practical ramifications are that at the very least it makes any future additions to circuits as good as impossible. Especially when you factor in the ancient fuse boxes these cables invariably run back to!
Then there is the age is a factor on it's own. One of the properties I have seen this in had the old thick rubber cables in, so even if they are testing ok are likely to be brittle and really need to be replaced anyway.
Also both properties I have seen this unsurprisingly have unearthed lighting circuits which is another issue in itself.
I guess I have a few questions on this:
Does this type of installation have a name?
On a condition report what code would you give it? (I assume C3 if ZS at accessory is ok? with a recommendation to rewire or at least monitor installation condition regularly)
Also is this set up mentioned specifically in any regs? if so, any pointers on where to look would be appriciated.
I did have a look at other threads and found the odd post eluding to this issue but nothing comprehensive, so any input you have on this would be good!
Thanks!
