Three phases per outlet block
Hello! There are three phases in the house. It is necessary to connect the outlet block - 6 pcs. The maximum possible load is decent (somewhere 6-8 kW) Can I use the VVG cable 4x2.5. Connect two sockets for each phase, and is the common zero?
Loading...
Hello! 6-8 kW is the total load or one outlet? If the load on the outlet is 6 kW, then the cross-section of the VVG cable 4 * 2.5 will not be able to withstand such power. It is better to play it safe and stretch a thicker cable - VVG 4 * 4. If 6-8 kW is the load on all 6 outlets, then the cable with a cross section of 2.5 mm.kv. will be quite enough. Well, as for the connection, everything is correct.
1. Trying to imagine a picture. House. Room On the wall in one place 6 outlets. 6 cables go to them, each with a finger thickness. This is not even met in the workshops.
2. It is possible to connect the thickest wire (supply) of the VVG-1 3x2.5 grade or similar to household outlets without problems. Due to the size of the terminals, clamps, holes for the wire. Already VVG-2 is connected with problems. A wire with a cross section of 4 and higher to household outlets does not enter either a screw terminal or a spring clip. To connect large cross-section wires, industrial sockets and plugs should be used. And this does not fit with the idea of a "residential building."
3. Sorry, but either there is something wrong with your terms of reference, or this is an SEO trick of the site owner.
4. There is a plus. The wall all the way from the shield to the sockets will be additionally reinforced with electric wires. :) .. The question is how to hang a picture or something else in the foreseeable future. For it will be difficult to drill a hole in the wall - everywhere it is reinforced with electric wires.
Why did I immediately clarify, on all sockets such a load or on one. If 6 outlets are to be used in a residential building to which 6-8 kW will be connected, then VVG 3 * 2.5 will not withstand such loads. The fact of the matter is that the terms of reference are not accurate, therefore, the option with VVG 4 * 4 was proposed . And, by the way, to 6 outlets you do not need to pull 6 cables the thickness of a finger ... one is enough, and the outlets themselves are connected in pairs by jumpers.
Hello!
1. Block of sockets - this implies the placement of 6 outlets in one place of assembly, in this case. Usually, a socket block is installed in the kitchen, and a socket block is placed near the TV to simultaneously connect a TV, receiver, VCR, etc. electronics. In addition to sockets with 220V, there can be high-frequency (antenna), Internet, telephone sockets in one assembly.
2. 6 cables are not in the wall. These are cables with electrical plugs inserted into a block of 6 outlets.
3. A 5-core cable with a cross section of 4 mm2 can be brought to the unit. (three phases, zero, earth). But it will be problematic to stretch through the holes in the installation box - it is difficult to bend a 4-mm-wire wire in small pieces, insert it into the corresponding holes in the box.If you can connect the wire to the outlet during installation, it is very, very difficult to insert the connected outlet into the installation box. So you have to put in front of a block of 6 outlets another distribution one and from it lead to each box with three wires (phase zero ground), here's the reinforcement of a piece of wall with a wire.
Well, and if a person has such a technical task, what is the other way out? So it turns out that you’ll have to torment with installing the outlet block in the wall, yes. As I understand it, there is no grounding either, it is also described in those tasks (only zero is common), so I lived not 5, but 4. But as for me, 6-8 kW is the total load, so VVG 4 * 2.5 will be quite enough only in case it really is such a load.
