How to conduct wiring under a stretch ceiling?

Electrical installation requirements

The first thing I would like to talk about is how to make the wiring under a safe ceiling safe. As you know, the live conductor can become hot, especially if it is wrong to select the cable cross section for power and current.

If the installation of the electrician is to be carried out on a combustible surface, for example a tree, you should consider the following points:

• The wiring must necessarily pass in a steel pipe or sleeve that will prevent the ignition of the wooden floor, walls or the same stretch ceiling when heating the cable.
• Joints between pipes must be additionally protected by seals made of non-flammable material.
• The cable for wiring under the suspended ceiling must be non-flammable, ideally also with low smoke emission. In this case the cable ВВГнг, ВВГнг-ls or the imported conductor - NYM will approach.

If you decide to install electrical wiring on a concrete ceiling, you can use corrugation instead of steel pipes. Its function is to protect the wiring against flame propagation in the event of a short circuit, and also to protect the film of the tension ceiling from melting when the conductor is heated strongly. It should also be noted that there is no need to protect the cable with a corrugated pipe to install spotlights;in this case, electricity passes through a step-down transformer that converts 220 volts to safe 12 volts. With reduced voltage, the cable does not practically heat up if the wiring is done correctly.

Features of power distribution

So, now let's talk, how correctly to make electroconducting under a stretched ceiling the hands. In the step-by-step instruction, installation on a concrete overlap will be made, which occurs both in apartments and in private houses.

Stages of electrical work:

1. Draw a wiring diagram for the ceiling wiring from the distribution board. We draw your attention to the fact that the wire must pass strictly parallel and perpendicular to the joint of the wall and ceiling. The junction boxes should be placed so that they can always be accessed for repair and maintenance. Do not negligently treat the drawing up of the installation scheme;without it you can get confusing and wiring the wiring will not only be uncomfortable, but also unsafe. Comparison of good and bad option of wiring you can see in the photo below.
2. Transfer the drawing to the surface using the building level( usually laser).
3. Use a perforator to make holes for the dowel clamps or clips( whichever you use for securing the wiring).The distance between the fasteners must be such that the wire does not hang after installation. As a rule, take a distance of 50 to 90 cm.
4. Install the junction boxes according to the scheme, the clips and secure the wiring under the suspended ceiling. First, the wire must be passed through the corrugation by means of a wire inside the broach. After that, the corrugated pipe is fixed in clips and connected to the junction boxes. The wire outlet from each end of the corrugation should be at least 15 cm for the connection of the conductors, as shown in the photo.
5. Connect the wires to each other and check the correctness of the work done by visual inspection, as well as a multimeter( to determine if the wiring is shorted).

That's the whole technology of electrical work. As you can see, it's easy to conduct electrical wiring under the suspended ceiling with your own hands, the main thing is to be attentive and take into account the provided recommendations. We advise you to immediately see a video example, which shows the finished kind of wire routing on the ceiling.

Alternative options for overlapping

To let you know how to independently install the wiring in the remaining overlapping options - reinforced concrete and wooden under a stretch ceiling, now we will briefly talk about the nuances during installation. So, consider the following tips from professionals to ensure that the wiring is safe and easy to maintain:

• If the overlap is a hollow-core slab inside, it is better to hold the cable inside the existing voids, which are usually located every 100 to 140 mm. Shtroblenie under the wiring in this case is strictly prohibited. Do not want to use voids, you can make an open wiring using corrugated or cable channels.
• It is necessary to weld metal pipes for electrical wiring on a wooden ceiling with welding. The junction boxes in this case must also be made of metal, with a degree of protection of at least IP 65.
• To ensure that the plaster does not crumble at the location of the cable, which will be slightly, but still heated, use a reinforcing mesh in the wiring harness.
• It is not recommended to conduct a cable under the suspended ceiling without corrugation for reasons that there is always a danger of flooding the neighbors from above. To once again protect the wiring from moisture, we recommend that it be placed in the corrugation, especially in the bathroom.

That's all I wanted to tell you about how to conduct the wiring under a stretch ceiling. We hope that now you know how to conduct electrical work and what to do to make the home electricity network safe!
