The heating was suddenly turned off, the house got cold. In order not to get sick in the off-season, it was required to install a kilowatt heater. But because the family is everywherereal kid, decided to install an electric heater for the battery. So that the child does not accidentally burn himself. But there is no outlet. Therefore, there is only one output, connect through an extension cord. I decided to assemble it myself, as I will feel more confident if the power strip does not overheat and does not spark under the curtains.
- In order to assemble an extension cord, I bought a block for three sockets, an invisible plug, it will interfere less with furniture and a wire three meters PVA 3 x 1.5.
Dear friend, to plunge into the atmosphere of the assembly, flip through the photos in the gallery.
We disassemble a tee and a plug in order to find out how long to cut the insulation:
With wire it is necessary to remove the outer insulation, this requires a special tool, unfortunately I do not have it. So in the old fashioned way, neatly with a knife (let the electricians not peck me, Amen). But I will cut the wire itself "fromgonorrhea ". A very cool thing, I recommend buying who does not have it.
I was not too lazy and tinned the wires, it turned out even very nothing.
After how the measurement was made, stripping and tinning the wires, it's time to install the wires in their places in the plug. Ground wire (yellow, stripe) centered. And the other two in their places. We clamp the wire with a bolt with sufficient force, but at the same time we try not to rip the thread. Loosely clamped contact, the first cause of overheating and fires. Tfu, Tfu.
Assembly pads are not a hassle. The main thing is to stretch the contacts well. Excess wire could have been cut out earlier. I didn't do it, I'm a lazy ass. Therefore, we put the excess in free space. In order not to pull out the cable with the wire from the block, we tighten it with a special clamp in the case.
This assembly it cost me 330 rubles. In this case, the outlet can be cheaper by 50 rubles. If you buy ready-made for that kind of money (280 rubles), then I offer us a thin wire 2x0.75 mm, plugs and pads without grounding. And the installation is not clear what. Probably not reliable. Photo in the gallery.
Now I and my household will sleep peacefully and warmly. Who is interested in attaching a table of loads for certain wire cross-sections. The first store extender was marked in red. And the second extension cord that I have. For the same money, plus grounding.
If you have a little skill in assembling an electrician, then I recommend assembling extension cords on your own in critical areas. But be aware that the author of this article is not responsible for your actions.
