I’m not sure what the purpose of this tool is.
When you have masonry walls and want to run a wire or water pipe, you need to cut a trench in the wall, lay in the item, then hard plaster over it.
When a wall is new you only sink in the electrical boxes and plaster over the wires. Water pipe are still chased in since they're too big to simply cover over.
The below picture is from our new home. You'll see the junction box is sunk in but the wires are on the surface of the brick. This all gets hidden behind hard plaster/stucco. If I later need to run another wire I'll need to make a trench.

Nice to see green/ yellow a universal identifier of ground, that ROMEX style wire is accepted, and that spectacular twist to bond conductors.
I have always said the many countries have a far superior method of housing construction than that which is so widely practiced here in the USA
You should see their regulations for gas appliances, the rules were updated just as we started the house so we changed the plans to meet the stricter rules. First, no gas appliance in a room less than 10 square meters AND that room has to have a window that opens. So, gas sauna became electric (6kw, 380V) and the house boiler with combined domestic hot water moved into the kitchen. It will be in a cabinet at the end of the kitchen next to the window. The cabinet will have vent holes in the bottom and top. Nothing stored there, just the heater.Quote:

Once we have that permit and the gas is turned on, the house is officially issued a street number (we know it's #6 ) and can be lived in as soon as we get there. It also makes us semi-residents so border crossing will be easier as opposed to impossible.
I'll put a video about the manufacture of these stoves in another thread, pretty modern place!
I'll return........Quote:

Some regulatory commissions can get on a power trip and swing from one extreme to the other, and I'm not saying all of that is bad because I have been a contractor and was required to procure permits and even to have licenses in many states which I fully understood the reasons for the necessity. New York city could carry things to an extreme at times and in California just because you held a contractors license from the state didn't give you a blanket authority to conduct business in any particular county or even city for that matter as each had their own little sets of standards and requirements. in one city my team could not even run our 12vdc control wires for the machines we installed even though a Licensed electrician did the final inspections before connecting the power unit to the power supply One electrician I hired said it was stupid to force his men to run the control wires in our conduits and race ways since they were an integral part of our machines pre made at the factory so he helped me obtain a class B electricians certificate, it took some time and mostly money but in the long run anywhere in the state all I had to do was to contact a licensed electrician to do the final connection to the grid once all inspections had been preformed.Quote:

Gas appliances can become bombs if not made to very ridged standards with quality controls and 3rd party testing. But just jumping through the hoops to get one installed can be frustrating to say the least.
That is a lengthy bit of exposed copper. What is going to cover those long twists?Quote:

depending on the country it may be trimmed and an insulated terminal sleeve placed over it then a screw is tightened to hold it in placeQuote:

since the advent and improvement of heat shrink tubing has become popular and in much thicker tubes allowing it to meet the +600v insulation quality required in many countries it could be they will use that.
the contractor may be required to leave the twisted ends exposed until a visual inspection is preformed by the building inspector
And inspected again after insulation is installed
Inspected bare, then covered with 4 layers of insulating tapes per code. Then inspected and sealed into walls never to be seen again (unless you try hanging a picture right through the box).
It also looks as though the wires are also welded at the ends before twisting
yes, they are welded...or as they're copper, would that be brazed?
That's done AFTER the twist, it would be hard to twist them after you stuck the ends together.
I'm equating that joint to something like wire wrap, only there's no sharp edge to bite into the copper. I'm guessing they have to be cleaned before twisting.
BTW, anyone thinking of soldering them may be surprised to find a twist is a lower resistance and more durable junction than soldering. Sticking the ends together just makes it more so.
I don't know if only joints to be buried in plaster are done that way since there will never be an inspection of them again. It seems regular exposed joints are more lax since you can get at them to put out the fire.
In Kuwait they have to use a conduit inside of the plaster walls but the black vinyl PVC 2mm thick is acceptable the box covers are left exposed but flush with the plaster. The German version of romex is the wiring used. Their reason for requiring piping is they figure sooner or later someone will overload as circuit and the wiring may have to be accessed for replacement Also in running a 20mm or larger conduit additional circuits can be added without the need to cut into the walls again except for where the branch circuits will be ranQuote:

The Kuwaiti who owned and lived in the main part of the house visited my apartment one night While I was showing him my micro machine shop in the converted bed room he marveled at all of the additional circuits I had installed. I told him that should we eventually leave that I would restore everything back to as it was before. he just said la,la,la,la, meaning no, no, no, no leave it as it is maybe another Amerike would want to lease the apartment. He spent a lot of time in my work shop learning to run the lathe and the mill as well as studying in my office reading books from my library.
