Electric plug. Types and basic parameters

Electric appliances have become indispensable in everyday use. That is why the electric plug today is the subject that we use every day.

Types of sockets and plugs

In any modern outlet there are three contacts: the phase (the main one, it is the voltage that is applied to the device); Zero (neutral, produces a reverse flow of energy from the device to the source); Grounding (protective, fulfills the substitution of a neutral wire).

Basic parameters of forks

Any plug connected to the device has many parameters. Especially important for any consumer are the following:

• The number of teeth available. As for electrical appliances, which are produced for European countries, then any plug has an electric plug for such a device having 2 teeth. Distinctive features are the whole of American technology, where there are 3 contacts.
• The form. The most common options are a round, square, flat plug.
• Design. You can distinguish such types as cast and those that need to be collected independently. The second option is an electric plug. Its advantage is the availability of the possibility, if necessary, to change the wire to a new one.
• Standard (used in Europe and in America).

Modern connection of the plugs is made of plastic, which is shockproof. This fact determines the long life of devices with such a plug. In this case, do not just focus on reliability. Any power plug must be easy to use and safe for the user.

It is safety that is one of the key factors, which is given the main role in the production of such products as an electric plug. This is achieved through the use of advanced technologies and advanced technologies.

Earthing-type plug

An example of such a device, which is endowed with all the above features, may be a plug with an electrical grounding. Until quite recently, in the days of the former USSR, an ordinary electric appliance user had no idea what grounding was. All because in ordinary houses it was not. In order to install the socket, it was necessary to simply connect the wires to the fiberboard terminals.

Today almost any electrical appliance has a plug with ground connection. But for it to work, you need a third wire, which is absent in most houses of old buildings. That is why, before the electrical plug, in which there is a ground, will be connected to you by an electrical appliance, make sure that your home network has a 3rd wire.

Now, having understood what the electric plug is, and what types it is, you can safely start to replace them with old electrical appliances. Just do not forget to take into account the power of the device itself, selecting a new plug for it. Correctly selected plug will serve you for many years.
