Replacing electrical outlet

The replacement, at home, a electrical wall outlets is one of the simplest and most frequently made ??by lovers of DIY. Of course, the first thing to do is dis-dall'interruttore general electric power supply, the necessary tools are typical for the work dl DIY at home, including: screwdrivers, wire strippers, voltage testers, pliers and scissors for electricians .

Conditions and tools replace electrical outlet

Plaque removal of coating of the box, in which it is necessary to change the socket, is a simple operation. The removal of the binding can be done by gently prying with a screwdriver on the back of the plate or loosening the screws that hold it fixed to the electrical box. In both cases it is necessary to follow a prudent not to damage the appearance of the same plate.

The metal support, which contains the fruits of the socket or of electrical outlets, must be unscrewed from the box below, generally there are two side screws. The fruits of electrical outlets can therefore be freed from the support and stay connected to electrical cables.

Normally you have to identify three different types of cables: live, neutral and earth. They should be between the reference standard colors, brown, blue and yellow-green, the section of 2.5 mm square.

The absence of one of the conditions, just described may already be a significant alarm signal about the safety and efficiency of the plant. The phase conductors and neutral must be avviatati respectively in the upper and lower clamp of the new socket, while the yellow-green must be connected to the central terminal of the same. Phase and neutral, generally, may also be interchangeable.

Considerations replace electrical outlet

The replacement of the plug may be due to an excessive absorption that has damaged. In this case, the part of copper wires that were avviatati into the socket can present clear evidence of overheating or burning. If it is necessary, therefore, the part of the cable that was screwed into the old socket can cut them off, leaving room for a stretch of next cable and not damaged that it must be suitably stripped.

Leave a fifteen cm of wealth cables will also in the future to do any other operations in an easy manner. In a cassette characterized by the presence of two or more sockets a solution often adopted is that of the classic bridge between the two sockets.

One of them is fed by phase neutral in a direct manner, while, the other socket derives its power from the first by means of the so-called bridge. Such a solution can not be extended to a larger number of sockets even if contained in the same box.

When the plugs are in different boxes the technique of bridge can be taken at the two outlets when they are in the distance of a few meters.

The limits of this technique are derived from unsafe conditions that are created when a pair of cables dimensioned for a certain absorption of electric current, with a simple bridge, may find themselves food loads that draw twice the current.

Using appliances in home electrical outlets made ??as described above, it is easy to see even the annoying interference phenomena on the various feeds.

Without these simple considerations, we have to fix the new socket or two new outlets in the corresponding brackets and screw them on the box in the wall.

The arrangement of the plate on the box ends mechanical operations. Providing, again, the power supply to the system is advisable to check the efficiency of automatic devices for differential protection, known as life saving. In systems of old factory it is generally present one, upstream of all other devices.
