The face fixings screws where probably tightened with a torque screwdriver.

24v impact would have been the weapon of choice to mangle those massive 3.5mm box screws and lugs

I do some work at a couple sport centres and when it has been quiet instead of the staff sitting around picking their ears they have been painting all the door frames , conduits , surface trunkings and ever light switches and sockets BLUE to match the walls

I hate it when tube and trunking is painted the same as the wall..... trunking and tube needs to stand out....its a work of art

Especially when that paint is applied one day after installation of conduit.

When recently on a day trip to York, I amazed my daughters by requesting a visit to Urban Outfitters.
"Why????" they said. "It's the most amazing maze of galv conduit I've ever seen, I could stare at it all day...." I replied.
Sadly I don't have a photo and can't find one online.

Go into most modern re-fitted shops like Hollister and they have pulled the old fashion suspended ceilings down you will see lots of galv conduit and tray re-exposed and on show

It was similar to this but bigger

I have seen a couple Youtube Vids from over th America and they love a bit of EMT conduit , I have seen runs of 25-30 tubes all side by side then spurring off here there and everywhere like the above picture. I think in certain places over there they have to run cable in a steel or metal system , they can't use any plastic stuff

It would be interesting to see how that lot terminates etc.
It's a pity they didn't render at least behind the conduit, though.

Got called out to an odd one. Dual RCD board and the left hand RCD went off and wouldn’t come back on. Nothing was being done at the time, couple were watching TV.

So went today and had a look. No shared neutrals.Narrowed it down to the kitchen ring and left hand side upstairs lights and utility extractor fan.

Both circuits had a dead short on IR test.

On the socket ring the L-N was a dead short but the L-E and N-E was fine. End to ends were fine.

The light and fan circuit was a dead short on all 3 for both cables.

However these circuits feed diagonally opposite sides of the building (it’s a huge farm conversion). There’s no loft space as it’s vaulted ceilings. So there’s about 40-50mm of space between the upper floor ceiling and roof at the apex. And approx 30-40mm between downstairs ceiling and upstairs floors

Initially I thought rodent damage, and could still be. But given the seperation of the circuits then I can only guess the rodent damage is close to the consumer unit. Or that it is poor workmanship with some errant capping/dodgy junction boxes.

Going back next week to try and locate the issue.

Anyhoo, after a long winded explanation. I noticed something else today when I had the cover off. See if you can spot it.

To help, the circuits from R-L (starting at the RCD) are

Kitchen ring (with the dead shorts)
Lounge and studio ring
Utility sockets
Integrated oven and microwave
Central heating
Kitchen and patio lights
Lounge, studio and rear patio lights
Upstairs left hand side bedroom and bathroom lights and utility extractor fan. (Again circuit with dead short in both the light and extractor fan circuit)

One less termination on LH neutral bar, than outgoing lines on MCBs.


Edit: On the fifth count I can see that's not the case

Damn i was just about to say 11 in each ...

2.5 sq mm T+E hanging off a B32 for oven and microwave?

I was just about to say the same thing................

Correct. I saw that about 30 secs after I took the board cover off.

Forgive me asking, but did you test both IR and continuity to rule out something plugged in?

Yes, and I got them to unplug everything in the kitchen anyway.

And it looks like the Hager blank is upside down.

It's not upside down, just not correctly fitted.

I had this sort of thing at a friends old house a few years ago - dead short that just made no sense, lifted boards and could physically see end to end the section of cable in question, undisturbed for 30 years. New length drawn in, examine the old..... after peeling off the outer sheath it revealed a manufacturing defect internally, one of the conductors was missing about 3mm of insulation. No idea how it had suddenly come to light after all that time.
