Odd flex

That scheme is used in an outdoor light fitting with photocell that I have. Brown and blue are the feed to the light. Black is a switched output from the photocell.

Possibly, but not as a result of that :-)

Ahhhhh. It'll have been the flex from a replacement submersible switch I bought to operate the pump in the cesspit at my last house. I now recall that it was much too long, so I chopped off the unneeded bit and chucked it in my junk box, likely 10 years ago. Never throw anything away!

That is where I have also seen such cable.

As for going to hell, it could be worse. You could have one of my apprentices.

He could not find the skip today.

"Where is it?" "It's outside next the van" "OK"

Comes back 5 minutes later

"I can't find the door to get back outside"

TBH, I have some sympathy. I've been unable to find my way out of buildings (usually hospitals) in the past.

On my first day at university, I spent half an hour trying to get out of Rutherford College. Kent graduates may sympathise.

German I think.

Colour blind electricians? Brian

I have some five core ex rotator cable somewhere all kinds of colours in that. Wire is used for other things. Brian

The old German colour code was Black - Live Grey - Neutral Red - Earth

Indeed.

And on a recent visit, I couldn't find my way into Keynes College. They seem to have moved the front door.

I was the first guest in a hotel in Sophia Antipolis in the late 1980's. It was still being finished off, and there were no signs up anywhere yet. Finding anything became a running joke.

No, the front door is where it always was. Unfortunately they've built three more front doors on ... the front!

well at least it will be s*it-proof, so suitable for external use.

No wonder they lost the War.

But won the EU ;-)

Wasn't the idea that black was live indicating death, and grey being not a clours was sort of neutral, and red was blood as it;s what makes use alive like the earth/soil makes teh planet alive. That's what I was told by a Ge rman research student that I found wiring a plug up the wrong way, but this was some 15 years ago.

Been there, done that back in the 70s in Eliot College which was very similar to Rutherford layout. Externally they look like 4 square blocks joined at the corners around and open quadrangle but inside the corridors become more like octagons and quite disorientating. Bob

They are, in fact, mirror images of one another, internally.

But once you'd learned your way round one, you could easily find your way round the other.

And IIRC, the rooms were numbered something like N2E1, which meant North Block, second floor, East side, room 1.

I was in Keynes, which was much easier.

Yes we Eliot inmates had to go over the Keynes for weekend breakfasts but I never had to navigate other parts of Keynes.

Exactly correct on the room numbering. Very logical. My room was E1E4. Being built on a hill, in Eliot and possibly Rutherford, the ground floor only existed in certain blocks. Happy Days! Bob

Hmm. Probably. I suspect rose tinted spectacles might be involved.
