Continuing the story of how in the evening returned home, but no wiring, I'll tell you right away that electricity was given at 22.00, exactly three days after the accident, when one of the shields burned out at night. A day earlier, one entrance was mounted and turned on, the other two a day later. I will briefly show and tell you how it all ended and how much it cost the residents.

Grannies endlessly went out to the sites, urged on the workers, shouting vying with each other from all apartments that refrigerators had flowed and everything was gone! and it really was gone. Sometimes they poured coffee to the electricians and gave them some lures, and they promised to do everything they could and could.

As you can see from the first picture, the electrical panels have been left old, although some of them are no longer closed properly. Have appeared new City slots, zero bar, Din-rail, on which the machines were placed and powerfulterminals.

Perhaps the most pleasant and useful thing in this story is that now the house is grounded, which did not exist before, that is, it was not provided for by the project and was grounded as best he could, if he wanted.

Somewhere a couple of years ago, according to all the requirements, a ground loop was already installed in the house, which was checked by specialists with the device, but it was useless and now, finally, it came in handy. Grounding was brought out with a green wire, which is bolted to the bottom of the shield (photo 3, managed to take off before walled up).

Photo 3. You can see where the ground wire is screwed on the bottom of the shield.

The power cable is a round copper five-core 6 squares. Electricians assured that not Chinese truncated, but GOST. In addition to the main cable, a separate wire for driveway lighting was laid in the same gate, 2x1.5 squares likely.

Since the grooves bend around the concrete lintels above the doorways, the old cable could not be simply pulled out and a new one started without crushing the walls. The fact that the strobe does not go straight became clear only after opening it.

But there is something in the work of the brigade that is a little alarming. For sealing the strobe was used a very economical method of filling voids - a sheet of foam was cut into strips, an adhesive mixture was applied to the foam and tightly inserted into the strobe. Rough sealing of the groove was partially completed in the evening before the line was switched on.

It seems that it is not entirely safe to use foam for terminating electrical wiring, and although the shtroba closed, the air in it will not circulate badly through the flap, which in case of a short circuit and burning undesirable.

On the ground floor at the exit from the shtroba the cable is packed in a corrugation, attached with plastic clamps and taken out to the general electrical panel, which stands inside the entrance.

It remains to carefully plaster the walls and whitewash or paint during the upcoming major overhaul of the entrance.

If we talk about costs, then each apartment owner had to fork out almost for 2000 rubles. This amount includes the cost of dismantling, installation and sealing of the strobes. It seems to be not too expensive, except for the losses from everything that people have deteriorated in three days without refrigerators. In general, we survived the surprise and well.

Still removed short videowhich shows the situation before and after the installation of the cables.
