"borrowed" switch feed

Hi all,

I'm a DIYer, and am amazed at the concept of 'borrowed neutrals', even from many years ago. Beyond laziness, what's the reasoning behind doing it? Seems like a recipe for disaster, with little to defend it.

Thanks.

Steve.
 
circuit
but a neutral from the upstairs circuit. this
unbalances both rcds. we're going to find this a lot.

Interesting point for future reference.



1. Put both circuits on same RCD (sorted lol)
2. Do proper testing to identify problems 'before' energisation of the system.
3. Correct the wiring at extra cost to customer as it's a code 1 ?
 
Nothing "New"

Just ALWAYS been bad practice.


Exactly my point, Prosparks.

It well known - it is also well known that it is a Big No no.

So why are people suprised and saying that they will have to look out for it?
