When we fix up a bathroom, before finishing it is necessary for electrical system design, then you put up then go forth under the trail and overlay it with tiles. A functional system, must be accompanied by several types of sockets, connections for external lights or ceiling lights, and to follow with the EEC in terms of safety.

Before starting the installation of the electrical system, we need to provide to make a detailed diagram, so you know where they should place light points , how many sockets and we need to calculate the length of the wires. In this case must be of adequate section and divided into three types, namely the red for positive, black for the negative and the yellow striped green for grounding.

After seeing the measure of electrical equipment required, we can eventually continue with the actual sketch, taking in a diagram which is particularly useful when the final posture. A plant in a workmanlike manner, should be performed as already mentioned in the introductory phase in the track, so let’s take some colored chalk, and begin to draw on the perimeter of the room parallel lines, one upward and the other in the lower about 30 inches from the floor. At this point, depending on the choice and the need to have the sockets, on the lines they draw other perpendicular to them, obtaining the branch of each. The same thing we do with a different color of chalk, always in parallel and then perpendicular, from time to time, reaching areas where they placed the switches for the lights, lighting, and other additional outlets for the mirror of the bathroom, the electric shaver, hair straightener, hair dryer and so on.

The design from the graphic point of view is now complete, so we have to act with chisels or better yet with a powerful tool to dig at the lines drawn with chalk, and create splines for the accommodation of wires. The depth should in this case be at least 2 cm, taking into account that we have within the cement block with a plastic tube that is used to insulate electrical wires. The latter, are then inserted already assembled inside the tube, using a special tool that knocking on the one hand, there carries the wires in the whole plant, making out on the terminal part. The installation is now complete, and after a preliminary test to confirm that they are properly laid, we can proceed with coatings and finally with mounting sockets, switches and lighting.
