Every person is familiar with such an electrical device as a receptacle. There are many varieties of them, the choice of which depends on various factors. This is one of the most common household devices. Sockets are the connection between the plug of household electrical appliances and the power supply network. The configuration of the equipment depends on its functions, as well as the country for which the device was manufactured.

During the operation of the power outlets with a grounding contact, a certain number of consumers are connected to them. If the old copies of the sockets could withstand a load of not more than 10 A, then the new devices are designed primarily for a total amount of voltage 16 A.

Device sockets

A power outlet is a device consisting of a protective housing, a contact element and a shoe.

The protective plastic case not only covers the contact elements, but also performs decorative functions.

The block acts as a basis on which contacts and the case keep. They are used for both open and hidden installation of a power outlet.Receptacle and its types

Its heart is a contact element, which can be made in the form of a keyboard or screw clamp. The plug must be in tight contact with the plates. This determines the quality of the outlet.

There are many varieties, the differences which should be understood before the acquisition.

Installation type

By type of installation there are two types of electric equipment are presented. Socket plug the flush fitting is suitable for indoor installation. Its main part (socket and pins) submerged in the wall. The body almost does not protrude to the outside. With the help of special mechanism in the bottom part of the product is fixed to the walls of the mounting box. The node wires embedded in and firmly pressed in. This design allows the plug to fit snugly to the contact plate.

Open-type receptacle attached to the wall. These varieties most often have various additional ornamental and functional elements.

Electrical circuit

Receptacle without grounding are the most common devices of the type in the former Soviet Union. They are designed for connection two wires – the “phase” and “zero”. This is true for those apartments where grounding is not provided. Are the majority among the buildings of the Soviet time.

Socket plug with grounding contact has a connector for the third wire. Vanishing in this case occurs earlier than the power supply stops later. Such devices are mainly used for connecting electric cookers, instantaneous water heaters, etc. Although it would be correct to any electrical ground. This increases the safety of its operation.

Exploitation

According to the method of use in everyday life distinguish sockets for dry and wet areas. This should be considered when installing indoor baths, swimming pools, etc.

Socket plug 16A power when installed in a wet room should have a high degree of protection. Otherwise, with such high power, unpleasant and rather dangerous situations can arise.

Such equipment is equipped with special rubber rings or membranes. They protect the contact elements from moisture. The internal flange facilitates condensate drainage. Such a plug socket with a grounding contact is often installed outside.

Equipment that does not have a security system in place is installed in dry rooms.

Polarity

There are one-way, two-way, and three-pole receptacles.

Single-phase species are distributed in residential buildings the most. She has access to only one plug. It is quite simple and convenient to mount. However, the disadvantage of the sockets of the submitted form is the inability to power some appliances. It will have to use a double or a tee.

The two-pole receptacle will allow to power two electrical devices at one point. The same principle and three-phase varieties. It connects three consumers.

There are standards for the quantity and quality of outlets in different rooms. So, for rooms in ordinary apartments for every 6 square meters. m should account for 1 outlet. If it is a corridor, then one device for connecting electrical appliances must account for every 10 square meters. m square.

For kitchens there are special requirements. If it is less than 8 square meters. m, then in this room should be at least 3 sockets 6-10 A and one with grounding at 10-16 A.

For the kitchen more than 8 square meters. m per 6 amp device should be larger. If an electric stove or oven is used, the socket must be 25 A with a mandatory grounding.

The body registers the level of protection against the ingress of foreign objects and moisture. Next to the sink install waterproof specimens of technology.

Receptacle is an integral honor of the electrical system of any apartment. Varieties of the presented technology allow to install it in rooms with a variety of conditions. You should correctly select one or another type of outlets, based on all the above characteristics of each of them. This simple and frequent device requires a serious approach to itself in order to avoid unpleasant situations and problems during operation.
