Blue used to be a phase colour in the not too distant past

I can't think of any other cable which would be terminated in that way and have two black conductors which need manually identifying for polarity apart from pyro.

Sure, but it doesn't alter my point. Whether blue was being used to identify phase or neutral, it is "interesting" that the two blue 'stubs' are connected to the black which is not identified with blue tape!

You may be right. I really don';t know for sure.

Pre harmonisation I would have identified the tails in exactly the same way. Black i.e. no tape would be neutral, and ideally red tape as live but in reality any phase colour as live, especially if it was on a blue phase supply.

I believe the cable is pyro from what I know.

The cable going to the switch is extremely strong, so much be copper wrapped etc.

Also, the cable with blue tape on it I have tested as live (providing my test driver was right!)

So I assume the one with two blue wires attached is neutral.

That's fair enough but, surely, at no point in time has it been acceptable to use the same colour to "identify" both neutral and line within the same accessory??

No John, but looking at the kind of work that has been carried out at the OP's property, anything is possible!

Very true - but, as I said before, the use of pyro at all would seem to be somewhat out of place in view of the general nature/quality of electrical work (certainly outdoor electrical work) at the OP's property!

Probably done by more than one person.

The first installed the switch using pyro, and the second came along, removed the front of the switch with a hammer, stuck a conduit gland into the side, and tried to supply a socket using T&E from the switch. Then gave up and ran the T&E into the house through a brick sized hole in the wall.

It's a switch, so maybe both of them are line conductors.

The odd thing is though it's a 2-gang switch, with a link, so where's the other switched live?

It is and was against regulations to identify phases in SP circuits as anything other than red/brown, regardless of which phase they are actually on. The only exception used to be SP sub-main circuits.

Sorted the socket.

my first thought when I glanced at the picture was 'why bother with the elbow?' then I saw the waste

Much nicer, did you re-use the existing cable or do it all from scratch?

Shame about the BG socket though!

MalekoUK · 8 Apr 2015

All from scratch, new sleeve through wall etc.

BG socket as it was half the price

After a few long summer days baking in the sun (the conduit, not you) you might find yourself wishing you'd splashed out on an extra saddle or two.

Yea the MK RCD ones are silly money. I do love all of the Masterseal range though.

I had a BG IP socket that just straight up died on me, no real loads had been pulled on it, no signs of water damage or cable burning, just refused to work.
