What is the best way to branch out to sockets?

Alexander asks:
I decided to replace the old wiring, although practical experience is not enough.

Question: what is the best way to make bends for a large (8-10pcs.) Number of outlets in the room and kitchen in the country? The load is a microwave oven, electric stove, kettle, toaster, refrigerator, heaters, table lamps, etc. in cold weather.

Of course, the simultaneous inclusion of all this equipment is unlikely, but anything can be, usually women do not think about it. If you install terminals in each box for each outlet, you will have to cut the main cable for all outlets, which reduces the reliability of the wiring, increases the throughput (although this may not be very critical) and increases its cost.

If you make bends in the "old-fashioned" way - wrapping them like bandages, then the main cable can be cut, which is a clear advantage. Moreover, the main cable can take a larger cross section.

Or the 3rd option to group and power with separate wires. All these, of course, are my “theoretical” considerations. What do you think about that?
Thank you in advance for your advice.

The answer to the question:
Firstly, if you turn on all the equipment at the same time, most likely the introductory machine will be knocked out. Secondly, do you have the whole cottage on 1 machine? I would recommend to make a separate line for sockets and connect it to a 16A automatic machine (no more), laying a line with a cable with a cross-section of 2.5 mm² veins. If the input allows you to simultaneously turn on more than 16A, then make two lines to the outlet groups and connect them to two different machines, respectively.

Almost all modern sockets are rated at 16A (check for yourself what is written on any of the sockets), connecting them to a circuit breaker with a higher rating results in a risk of overloading the socket itself, for example, when someone connects a lot of things through an extension cord.

Thirdly, terminals are not the best option for long-term operation of outlets, although if you do not overload the line, then everything will be fine.

Fourthly, the line does not have to be cut if done by wrapping - this is good, but when the connection weakens and worsens - it is bad. Moreover, twisting can not be done (according to the PUE). It is better to cut the wire and make a good twist fixed with a PPE cap. Or solder / weld. If there is where to get the crimping pliers - you can also connect the twist with a sleeve, it will also work fine.

But the third option is ideal, you can put each group connected by a separate wire on a separate machine. It’s safer and safer, in fact, from this I began my answer! If you have any questions - write!

p.s. the scheme when everything is connected to separate lines is called a "star", and when from one outlet the wire goes to the next "loop". The star is more reliable, and the cable is cheaper. But when the wire from the first outlet is burned off in the loop, the others will not work.
