Yeah, err, sorry guys. That fourth panel may be my fault. I had a coughing fit earlier and may accidentally have invoked the Great Old Ones to arise and devour the Earth. Again, apologies for any inconvenience this may have caused.

"Nafl'fhtagn throdog r'luhhor ng."

I think you can resolve your guilt with a little homemade ciabatta bread. 

So who's responsible for the 2nd panel happening RIGHT NOW...?

When they run short of cash I'm sure they'll come up with some new idea that must be implemented for "safety reasons"

Nailed it !

Some modern regs are just daft. FFS I live in a 100 yr old house that was retrofitted with power in 1935 when power first came to these parts. Pop was just a lad and said he could remember when incandesant lights were fitted where he grew up which is 100yds from where I am.

In the nearly 40yrs being here not once has there been a need for RCD protection and we're all still alive and the 3 kids we raised also.

if you have never tripped a GFI you haven't worked on enough old TEA 

It is also possible that he's never had a GFI before his suitably old TE.

I tripped mine on the 428b because of a manufacturing fault.

Edit: In the 428b, that is.

Slight swerve:
My workshop has a 3-phase GFI covering all outlets and I fitted it because it is required in new construction. Workshop is in garage, which originally had just a light circuit lit from my house, and a single phase feed for outlets, also fed from the main breaker panel. I put in a new breaker panel fed directly off the meter board and installed fixed outlets (and a system with contactor-operated and motor-protection switched outlets for all three-phase consumers, like drill, lathe and compressor.) in the mechanical workshop as well as in the "fine workshop" where I have computers and electronics. The bench is (mostly) controlled via a contactor, like the outlets in the mechanical workshop. There is also a emergency stop circuit that will kill all appliance and machine power. I also have signal lamps outside showing status of workshop power so I'll not forget them on.

Right now he is doing untold damage to the reputation of the USA. He wants to become a dictator and I suspect that we could see similar things over here with Johnson when the time comes, they both have the same backers in common and they are also friends together, god help us all it does not help anybody all of this at all.

No RCD BS here !

My 99.6yo mother lives in an 1840 house. She recently overflowed a bath on the top floor. "Luckily" the water went down the central ceiling lights of the floors below, not down the walls. Even so, one ceiling light rose started fizzing and became covered in carbon deposits. An IR camera showed there was no smouldering behind the rose.

All in all a very close shave.

If there had been an RCD protection on the 30-60yo wiring, it would have tripped, thus avoiding the fire risk.

Have access to a 2KVA isolating trannie. 
However it's currently in the mechanical workshop doing duty on an old B&D drill press known to bite according to it's previous owner when he gifted threw it my way.

When you've been playing with things that have the potential to bite you for 50+ years you well learn how to manage risk.

Yes well there's another good reason why all circuits here are still on the original wired fuses especially lighting circuits where ratus ratus are prone to creating havoc in ceiling spaces.
Single story here where any new builds are also supposed to tank bathrooms like they did in the old days in upstairs bathrooms with lead floor linings and floor wastes.

Really... is that even possible...?

As long as he keeps flinging flaming shit everywhere, nobody is noticing the election-tampering that will keep McConnell and his cronies in control of Congress. FFS... that is how bad they are; it takes this level of outrage to distract everyone from the evils they're up to.

At the end of the day, keeping the power they've stolen is all that really matters to them; they couldn't care less if they destroy the nation. They will launch Armageddon before they let go of it, too.

Resident Chump is the symptom, not the disease.

[mnementh]

The cynic in me says this will all work out in their favor; when Biden takes office and the inevitable investigations and inquiries come... they can claim any evidence uncovered in the Capitol is inadmissible because of these fuckwidgets ransacking the place.

And so what I really have to wonder is... was it really random wingnuttery, or was it a deliberate attack, planned for precisely this after-effect...?

Watergate was just a trial run.

The current was too low to blow the 6A fuse (which nominally protects the wiring), but possibly sufficient to start a fire.

Johnson doesn't have the conviction. Give him a plate of cucumber sandwiches and tea (no, not our version, the liquid one) and turn on the cricket coverage and he'd forget what he came for.

McBryce.

[bd139]

This US drama is perfect viewing after The Expanse finished and after my sausages earlier  . As for the disease, much like here, it is the lack of education, critical thinking and reasoning skills that causes these situations.

As for Johnson, his public and private persona are completely different. He's dangerous, decisive and everything is done with intent, even the unintentional looking stuff. If you did give him a cucumber sandwich, he'd fuck your wife and +1 his illegitimate child count (check wikipedia for his statistics)

Single story here where any new builds are also supposed to tank bathrooms like they did in the old days in upstairs bathrooms with lead floor linings and floor wastes.

I was daydreaming designing a building in my head recently; the details aren't relevant. That led me to thinking how you properly tank a room (like a subterranean plant room) with modern materials. All the waterproofing I've seen in recent years relies on polythene, and I'd be very nervous of designing in a plastic barrier that would be guaranteed to survive 50 years, let alone the few hundred years that I reckon most buildings ought to have as a minimum design life. I'd never have given lead a thought, but there are examples of that surviving millennia. Somehow I can't see someone giving approval for lead sheeting in a modern structure.

[Specmaster]

Split load boards were one of the previous iterations of the IET's money making schemes, first in plastic consumer units, then in metal ones. The latest version is metal consumer units with every circuit protected by an RCBO (combined GFCI and overcurrent device).

When they run short of cash I'm sure they'll come up with some new idea that must be implemented for "safety reasons".

I can assure you that there are some safety benefits from having dual RCD's on boards, they were not just introduced as yet another money making scheme, they were introduced to respond to a specific safety issue and that was rain water ingress into lofts through leaks in the roofs of buildings that while not sufficient to make their presence felt with damp patches becoming visible on ceilings, or worse, water dripping through the ceilings. The problem was that there had been a number of fires being iniated in lofts where water would drip onto the fibreglass wool used in lofts for insulation and this was enough in the vicinity of light fittings to cause tracking and eventually ignition of the wool. I was working for Crabtree Electrical at the time and there seemed to be a few of these fires developing in the housing stock of a local Authority in Essex. In my position as specification engineer for Crabtree whose job it was to work with local authorities and consultant engineers alike, getting Crabtree products written into the specifications of new buildings and also rewires of public buildings. I was asked if Crabtree could develop a solution for this, and it was deemed that the best solution was to develop boards with 100A main isolator, feeding a 100mA RCD feeding a busbar for lighting and other fixed circuits, and also fed from the isolator a 30mA RCD feeding another busbar for sockets and any other circuits needed personal shock protection.

These were duly designed and tested and approved by the LA, and then they were introduced into the catalogue and they then quickly became adopted by other LA's etc and other manufactures produced their own versions. It was then adopted by the IET and became a standard in the regulations.

I was involved in a few other special projects that have since become far more common practise.

Still used for roofing and flashing.

Here it's done with grading to a floor waste either by diminishing framing or concrete with an appropriate fall.
Timber flooring under overlays...linoleum, tiling etc must be tanked and typically with a resin pour.
All this assumes the build with be inherently stable for decades so for it not to crack which is where I'd prefer a butanol sheeting or lead to better accommodate any movement.
Trouble is, lead these days is horrifically expensive.

This is true, the flashing above my front porch recently failed because of a shrub that attached itself to it and then tried to grow in the small space behind it. This pulled the flashing out of the mortar and then rainwater, during a really heavy thunderstorm run down the wall, and ran through the wall into the distribution board causing the electrics to crackle and hiss and then disconnect the supply. Had to have an emergency builder come out and replace the lead flashing in order to get the power retored.

In the swedish long-time storage of nuclear waste there is a combination of cast iron alloyed with magnesium (making it ductile), a layer of copper, and bentonite clay. It is calculated to remain stable for 100000 years when embedded in bentonite-filled chambers 500 metres down in bedrock.

Copper and/or stainless steel with bitumen or similar stabilisers would probably suffice.  Studying construction requirements for Biosafety level 4 laboratories is likely to be useful.

I think, I forward this request to a more approbiate place   

Dave is asking for some TEA support:

If anyone knows of any decent test gear that isn't being marketing or distributed well, let me know though. I do want to expand the product portfolio.

Especially if you are having some ideas about a decent LCR-meter.       

Edit:

I'd like one, but it's hard find something good without an already well established distribution chain and low prices.
Brymen works because they have pretty horrible marketing and distribution in a lot fo the world, and the margins are good, so they are winners for me.
If anyone knows of a suitable one on the market please let me know, I do want to expand my product portfolio.
