Electric goods 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 threecontact: phase (main, it is for him to apply voltage to the device); zero (neutral, produces a reverse energy flow from the device to the source); grounding (protective, fulfills the substitution of a neutral wire).
Main 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 with 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 you need to collect yourself. 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 fromplastic, 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 security that is one of the keyfactors, which is given the main role in the production process 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 withall the above features, may be an electrical plug with ground. 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 hasa plug that has a ground connection. But for it to work, you need a third wire, which is missing 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, figuring out what is electricalfork, and what types it happens, 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. A properly selected plug will serve you for many years.
