I'm replacing an old dilapidated sensor for switching lights on at the side of my house and was intending to do a like-for-like rewire. There's a single cable running to the sensor - I believe it's called Multi Core Circular ( 4 core - Brown, Black, Blue, Yellow/Green). The old wiring is as follows:-

Brown to Brown
Red to Blue
Blue to Black and Yellow/Green

What's thrown me is that the Yellow/Green wire (in the cable) which I associate with Earthing is wired with the Black to the Blue in the sensor. Would really appreciate views on why it's wired like this and opinion on whether this is correct and safe.

Q. Why
A. Don't know, probably not enough cores in the cable of the right colour

Q. Safe
A. Not really, its confusing.

Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?
