Most often the need to pave an electric cable into a trench in the country area occurs if the street lighting should be made on the poles or carry out electrical wiring in the bath. In this case, it is very important to comply with the standards (in particular SNIP and PUE), as well as take into account safety techniques in electrical work. Next, we will provide for your attention the cable laying technology in our own hands.

Electrical installation requirements

First of all, you need to tell you what regulatory documents can affect how you will perform the installation of electrical wiring in the earthen trench. So, we recommend to take into account the following restrictions according to PUE rules, SNiP and GOST under electrical work:

Considering these requirements and rules, you can be sure that the cable laying in the trench will not attend you and the domestic wiring line! This is certainly not all the restrictions that exist in the PUE and SNiP rules, but for the home conditions of the claims provided, even when the site is connected from the post to the house.

Technology laying do it yourself

So we approached the main issue of the article in which we consider how to properly pave the electrical cable in the ground on their own. In order for the instruction to be comfortable and understandable, we will provide it in stages.

That's all the technology of cable laying under the ground in the country area. As you can see, spend the line at home is not so difficult. More time and effort will go on land - digging of the trench.

1. Use only a special armored conductor. Such brands like, and the aaber is better not to choose. The first two cables do not have sufficient protection, and for working with the last brand of the conductor, certain skills are needed.
2. The diameter of the metal pipe, which will pass through the foundation of the private house (if there is a need for), must be 2-3 times more than the diameter of the email itself. cable.
3. If the depth of the landscape of the Earth in your region is deeper than 70 cm (the depth of the trench), be sure to secure the protective pipe so that it does not break and does not deform.
4. Use a plastic corrugated pipe (DKS) to protect the electrical wiring under the ground is prohibited. After a year of corrugation, all its protective properties, which are so weak, will disappear.
5. Try not to carry out the guide of the conductor under such zones of high load, like: playground, parking, garden tracks.
6. There is no uniform opinion or rules in the regulatory documentation, with respect to the minimum cable cross section for laying in the ground there. In practice, the cross section of 10 mm 2 for copper and 16 for aluminum is most often used. Focus only on, and also consider that the line must be armored.

Nuances when laying in winter time

Well, the last thing I would like to tell - whether it is possible to lay the cable under the ground at low temperatures, and in particular in winter. Electrical work in winter are allowed, but must be taken into account the following norms and rules:

• Before laying wiring in the trench, you need to warm the conductor in the warm room or using the transformer. The last method is not recommended to use if you have not encountered it earlier, because This requires certain skills.
• After heating, you need to quickly make the power line. If the temperature on the street is not lower than -10 About with you have a time hour, from -10 to -20 about C - no more than 40 minutes, below -20 Oh - half an hour maximum. If in winter the temperature is lower, the electrical installation is prohibited.
• Without preheating, a cable underground is allowed in the following cases: if the temperature is not lower than -5 ° C, and the high pressure conductor itself; If the temperature is not lower than -7 ° C and the cable is insulated, -15 ° C. If the PVC isolation is either rubber, -20 ° C in the event that the insulation of the veins is represented by a polyethylene sheath or rubber and an additional lead sheath.

That's all that I wanted to tell you how to perform a cable laying in our own hands. We hope our practical advice, instructions and the provisions provided by the standards will help you when installing at home!
