What cable to choose to connect the outlets ?

Let's start with the fact that according to modern requirements for socket cable must be copper, be sure to ground (ie, three-wire or five-wire) and a section of not less than 1.5 mm2 in accordance with the SAE Table 7.1.1:

Here it should be clarified that under the group network means the line of boards to sockets, lighting and other electric receivers.

It is now a little clearer what cable to use for mounting the female line power at 220 volts.Here it should be noted that the blaze from the junction box to the cable outlet section of 1.5 mm2 is not advisable, becauseIn this case, connect the appliance to the powerful it will not work, if required.It is better to take a single-phase section with a margin - 2.5 mm2.

With regard to the three-phase wiring, there is already the case may be different, becausewith section of 1.5 mm2 five-wire cable can withstand a load of 10.5 kW, according to the table:

This is enough to connect to powerful electrical outlet used in the home.However, experience shows that even in a network with a voltage of 380 volt conductor take with a reserve, namely, 2.5 mm2.

C of conductors sorted thick, now let's talk about the other, not less important question - what type and brand of wire pick.The fact is that today there are many fakes, the use of which may cause ignition wiring.The same wire SPAP dangerous power tools.We recommend to use the outlets of the brand VVG cable VVGng or NYM.

If you want to spend the wiring for the female group in the apartment or private home, choose the brand VVG enough.In fire-hazardous areas, for example, in a wooden house, be sure to recommend the use of sockets VVGng cable or a more expensive import analogue - NYM.

That's all that I wanted to tell you on this issue.To consolidate the material provided, we have decided to summarize and again specify which cable brand and cross-section is better used for outlets in different cases:

• to connect the washing machine, TV and others are not very powerful electrical household appliances - VVG 3 * 2.5 mm2.
• to connect powerful devices in the three-phase network (for example, if the garage is necessary to connect the pump to the powerful 380 volt or three-phase plate in the kitchen) - VVG 5 * 2.5 mm2.
• socket group in a wooden house - VVGng 3 * 2.5 mm2.
• If you are 100% sure that the socket will be used solely for the lamp power supply or other low power devices can draw a conductor cross section of 3 * 1.5 mm2.
