What are Plugs and Sockets
In order to understand what electrical plugs and sockets are, we must first clarify: Plugs and sockets are elements used to establish an electrical connection between two or more components (between an electrical system and an appliance, between two appliances, between a generator and a device, etc.).
The electrical connection between a plug and a socket is established mechanically and quite simply:
Sockets (also called female) have only holes, from these holes the electric current "comes out" and they are intended to accommodate the plug. A socket outlet may or may not be wall-mounted, depending on the model and function of use.
Plugs (also called male plugs) have metal pegs, which must be inserted into the holes in the sockets. Plugs (when not in use) are not exposed to electrical voltage, unlike sockets which are always exposed to voltage. Plugs and sockets are used in many different contexts and areas.
It may seem obvious, but without them household appliances, televisions and computers could not function at all.
Plugs and sockets are not all the same and differ according to different characteristics, such as the number of plugs or the intensity of current supported. Plugs and sockets are classified as 'electrical equipment', which means that even though they are commonly used, they must be used with the utmost caution, as well as meeting the safety requirements of current legislation.
How plugs and sockets work
To properly understand how plugs and sockets work, it is first necessary to understand how electrical current is carried from a source (a plant, generator, etc.) to an electrical appliance, device or equipment.
The electrical current circulating within a system, whether domestic or otherwise, is composed of a flow of electrical charges. The holes in the sockets are the exit point for this current.
When a plug is plugged into these holes, the current enters the hole and flows through the cable to which the plug is connected to an appliance or device.
An electric cable has three conductor wires: a blue, a brown and a yellow-green wire. Each of these wires must be connected to a pin in the plug. The blue and brown wires are the ones in which current circulates, while the yellow-green wire (called "ground") has a safety function.
The yellow-green wire should be connected to the central pin of the plug: in this way any current leakage will be sent to the earth socket, via the central contact of the socket where the plug is connected.
There are also several safety measures that you should be aware of, for example, sockets should be placed at least 40 cm above the floor, so as not to run risks in case of water leakage or flooding (especially in bathrooms and kitchens).
Another essential safety measure is to make sure that plugs and sockets are made to standard and with optimal materials, so as not to run the risk of accidents.
Areas of Use of Plugs and Sockets
It would be almost impossible to list all the areas of use of plugs and sockets, because without them any electrical or electronic device would not work!
If we consider that nowadays, except in very rare cases, almost all areas are invaded by devices that run on electricity, it is easy to see that plugs and sockets are present almost everywhere!
Below is a list of the most common areas of use:
- Domestic environment
In every home, more and more appliances and devices constantly need electricity to function (or recharge). For this reason, the use of pins and needles is a must.
- Working environment
Even in offices, schools, hospitals and all kinds of workplaces, there are a lot of electrical appliances: not having sockets is unthinkable.
- EntertainmentConcerts, theatres and cinemas all make use of a large number of electrical and/or electronic devices. Hotels, restaurants and leisure facilities of all kinds are also equipped with them. Consequently, here too we find the use of plugs, pins and, of course, sockets.
The areas of use for electrical plugs and sockets are innumerable and difficult to list exhaustively, but whatever the area of use, it is important to ensure that these elements are not damaged or of poor quality, so as not to incur in dangerous situations such as current overloads, short circuits or, in the worst case, fires.
Types of Plugs and Sockets
There are many types of electrical plugs and sockets on the market and they all differ in features such as:
- number of pins (or number of holes, in the case of sockets)
- type of pins or holes
- current amperage supported
In Italy, for example, the most common sockets are the 16 amp sockets and the so-called 'German' sockets (with two side contacts), but many others are also used.
Among the most common types of plugs and sockets we can find the following models:
Mobile or fixed sockets
Sockets can be fixed, i.e. connected to the system without the possibility of removal, or mobile, i.e. connected to the system but removable (as in the case of power strips or multi-sockets).
- Italian sockets and P11 Italian plugs
Also known as Italian sockets, these are the most common sockets in Italy. They have 3 holes and are 10 Amp sockets. They contain Italian plugs (P11), i.e. Comb plugs (with 3 pins).
- P17 sockets and plugs
P17 sockets and plugs also have 3 holes, but are 16 Ampere and accommodate P17 plugs. Compared to the P11 sockets and plugs, as well as differing in amperage, the P17 sockets and plugs also differ in larger and more distant holes. Of course, the corresponding comb plugs also differ in size and distance between the plugs.
- Two-way sockets These are sockets which, due to the shape of the holes, are able to accept both P11 and P17 plugs.
- P30 sockets
These are sockets for German "Schuko" plugs (which do not have a central pin). These plugs have two thin metal clips on the side for earthing.
These are the most common models, but there are many others that vary according to the country or continent in which they are used. Before a trip, therefore, it is a good idea to consult which sockets you will find in your next destination in order to buy the right adapters!
