I think the neutral might have been a bit loose!

Open ended cable chucked under the office floor tile, they could've at least turned the Isolator Off !

 

[sheppertonspark]

DIY at its best.

Don't put the junction boxes in the wall cavity it makes fault finding really hard - Builders again.

Buried in the Lounge wall, neutral continuity fault on Ring Circuit, found it with a Fluke cable tracker, couldn't believe how accurate it was.

The cable had been cut when they chased in some speaker cables, The line on the wall is where the tracker said the break was, impressive bit of kit.

 

[Mike Johnson]

Impressive bit of kit indeed, at the cost I would expect it to repair the break automatically as well.

And make tea for you as well

Worked in a large government building where majority of lighting was wired in blue, black and earth single, blue being phase and black neutral. The sheer amount of fittings with reverse polarity was scary.

are you sure it wasn't black line and blue neutral?

most fittings can work reversed.... its just when line somehow gets connected to cpc that things get tricky... as the upside down sticker in the picture would could lead to

It would have been pre colour changes I expect from a 3 phase db with blue being the phase colour supplying that particular circuit.

That's the way around I'd expect. We changed to blue because it was the most common neutral colour, and away from black as neutral because it was used as live in some countries, as it is now in the UK.

 

[Dave OCD]

It all depends on the age of the install, which we don't yet know.

And what a well thought out move that was. Would have been far better keeping it as it was.

Had similar last week. Building from around 2000, with emergency lighting using black for neutral, red switched live and blue permanent live. Strange thing was this was all in some sort of shielded flex, so I couldn't understand why these colours were present.

I thought it was originally but traced it back to find the circuits wired in red, yellow, blue singles with black neutral. All fittings had been changed to led and working with reversed polarity. Only realised when we went to test.

 

[Dave OCD]

Ah old Dave guessed correctly.

That's a strange one. Was there a yellow in it or just red/black/blue?

Red, black, blue & green/yellow, with shielding.

Was thinking maybe a yellow core had been cut back, but I'd changed a load of fittings and don't remember any signs of another core.

Was it the wasps or the mice that eat the phone cable?

Ahh photo too large for the server to process.
