Iako se čine sličnim, obe imaju okrugli oblik sa dve igle i funkcionišu na naponu od 230V. To objašnjava zašto neki turisti koriste evropsku utičnicu sa britanskim brijačem ili se pitaju zašto brijač ne može da se priključi na Schuko utičnicu u španskom hotelu. U stvarnosti, one su različite jer prečnik i razmak igala nisu identični jer su dva standarda izmišljena za različite svrhe. Nije važno da li vam je potrebna neka informacija o ovim utičnicama za vaše putovanje ili znate kako da povežete kupatilo. Ovaj vodič objašnjava od čega se sastoji svaki standard, koje su razlike i kako ih razlikovati vizuelno.
Ne, jer iako su utičnica za brijače i evropska utičnica dve različite entitete, one nisu direktno zamenljive jedna sa drugom. Britanski standard za brijače BS 4573 obavezuje korišćenje dva komada cilindričnih žica debljine 5.1 mm sa razmakom od 16.7 mm i ima snagu od 0.2 A. Nasuprot tome, Europlug standard Evrope koristi dva komada cilindričnih žica debljine 4 cm i njihov razmak se kreće od oko 18.6 mm do 17.5 mm i imaju snagu od 2.5 A. Iglice brijačke utičnice su mnogo šire od onih Euro utičnice, što znači da prva neće stati u utičnicu tipa C, E ili F. Takođe, treba napomenuti da postoje određene tehničke karakteristike za ove utičnice. U stvari, sve britanske utičnice za brijače imaju transformator, imaju propise o protoku struje utičnica i njihovim snagama.
Ovaj utisak je potpuno opravdan s obzirom na to da su dve utičnice potekle od jednog pretka i imaju zajednički izgled. Britanska brijačka utičnica je utičnica sa dve okrugle igle i nije zaštićena i mala. Europlug je takođe utičnica sa dve okrugle igle i nije zaštićena i mala. Na prvi pogled čine se istim.
U stvarnosti su nekompatibilne u tri situacije. Prvo, njihovi prečnici su različiti, tako da brijačka utičnica ne može biti umetnuta u Europlug utičnicu. Drugo, razmak igala je različit, tako da čak i da imaju isti prečnik, brijačka utičnica britanskog dizajna ne bi se spojila sa Europlug utičnicom. Treće, zbog toga što britanska utičnica za brijače ima izolovani transformator, ima različite električne karakteristike od Europlug utičnice.
Jedna napomena treba da se napravi: postoje neki utičnici za brijače koji imaju duže kontakte razvijene posebno za korišćenje oba tipa utikača. Mnogi multifunkcionalni sistemi za brijanje rade sa različitim tipovima utikača kao što su američki tip A i australijski dvopinski. Dakle, ako govorimo o standardima, izjava da utikači nisu kompatibilni i da utikač ne odgovara utičnici je tačna, dok u stvarnosti postoje posebne utičnice koje omogućavaju da se ne doživi ovo nesporazum.
Britanski utikač i utičnica za brijače definišu se u BS 4573, prvi put objavljenom 1970. godine. Utikač ima dva okrugla pina prečnika 5.1 mm, takođe poznatog kao 0.2 inča. Razmak između pinova je 16.7 mm, što je otprilike pet osmina. Utičnica je ocenjena i ograničena na 200mA. Iako BS 4573 ne postavlja ocenu za utikač, primenljivi IEC raspored mu dodeljuje 0.2 A.
Dizajn je nasledan, a ne izumljen. Dimenzije pinova odgovaraju dizajnu 5 A dvopinskog utikača uvedenog u zastarjelom BS 372 iz 1930. godine. Jedina funkcionalna razlika između modernog brijača i njegovog pretka je prisustvo izolovanih rukava na pinovima nove verzije i drugačiji dizajn držača kabla koji omogućava da kabl uđe u utičnicu sa vrha umesto sa strane.
Ono što razlikuje utičnicu za brijače od bilo koje druge utičnice nije raspored pinova, već ono što se nalazi unutar same utičnice. Uređaj za napajanje brijača koristi izolovani transformator, što objašnjava sigurnost korišćenja takve utičnice na mestima gde su sve druge utičnice zabranjene. Važna funkcija izolovanog transformatora je da odvaja krug brijača od zemlje, što znači da kvar uređaja ne uzrokuje nikakve probleme za korisnika. Uređaj takođe ograničava električnu struju: prema IEC 61558-2-5, uređaj mora imati minimalnu snagu od 20 VA i maksimalnu od 50 VA.
Gornje činjenice definišu tri praktične karakteristike proizašle iz ovog dizajna. Izlazna snaga je niska, tako da korišćenje utičnice za brijače neće omogućiti napajanje fenom za kosu bez obzira na korišćenje adaptera. Uređaj je označen znakom za brijače prema IEC 60417-5225 i ponekad čak ima reči “samo za brijače” označene na njemu, iako ovo poslednje nije obavezno. A dizajn obično ima dve utičnice, koje normalno snabdevaju sa 230 V i 115 V, omogućavajući tako posetiocima iz Severne Amerike da koriste svoje uređaje bez konvertora napona.
Zbog ograničenja električne struje, utičnica je sigurna za svoju predviđenu upotrebu: za povezivanje električnih brijača ili električnih četkica za zube pored lavaboa. Britanske električne četkice za zube takođe imaju BS 4573 utikač, čime se dokazuje da su oba uređaja podložna istom standardu. U slučaju adaptera za brijače umesto utičnice za brijače, BS 1363-3 zahteva da ima osigurač od 1 A, sigurnosne rolete, izolovane rukave pinova i oznaku “SAMO ZA BRIJAČE”.
Šira porodica uređaja za povezivanje i kako specijalizovana utičnica poput ove odgovara među uobičajenim tipovima, razmatrana je u našem pregledu različitih vrsta električnih prekidača i uređaja.
Europlug, koji je takođe poznat kao Tip C i CEE 7/16, je ravna utičnica sa dva pina koja se koristi posebno za opremu klase II širom Evrope. Glavna razlika Europluga od drugih utičnica leži u njegovoj izolaciji, a ne u fizičkim karakteristikama. Pošto utičnica nije uzemljena, može se koristiti u bilo kojim evropskim utičnicama, pod uslovom da ima izolovane pinove. Konstrukcija utičnice onemogućava korisniku da dođe do aktivnih komponenti dok koristi utičnicu u utičnicama različitih dizajna.
Veličina Europluga je 4 mm za pinove sa smanjenim razmakom. Prvobitno, razdaljina između pinova je oko 18.6 mm i postaje kraća od 17.5 mm na krajevima pinova. To je učinjeno namerno, jer su pinovi malo nagnuti za savijanje, što im omogućava da dodirnu kontakte napravljene za utičnice veličine 4.8 mm, čime se omogućava korišćenje Europluga u francuskim ili belgijskim utičnicama.
Europlug može biti označen sa 2.5 A i 250 V. Međutim, niska ocena je rezultat korišćenja Europluga u lampama, punjačima i elektronici, a ne ograničenjima utičnica. Svaka evropska utičnica može podneti do 16 A zahvaljujući zaštiti obezbeđenoj u električnoj instalaciji.
Bitno je razlikovati Europlug od drugog tipa Euro utičnice CEE 7/17 ili kontura utičnice, koja ima okrugle pinove od 4.8 mm unutar okruglog tela i široko se koristi za opremu koja troši veću snagu. Iako se na fotografijama donekle slično izgledaju, CEE 7/17 utičnica neće odgovarati Europlug utičnicama.

The two pieces of information to keep in mind are 5.1- and 4.0-mm diameter and 16.7- and 18.6-mm spacing. This also means that the 5.1-mm pin is too thick for a connector designed for 4 mm and that the 16.7 mm distance is too small for a connector having the contacts at 18.6 mm apart at the inlet.
This is where the two diverge most sharply, and it explains why they exist as separate standards rather than as variants of one.

The effect of the transformer must be clearly outlined: shaver sockets are not power sockets because they have a low power rating, but because the isolation that makes them safe means that they cannot pass much power. Trying to draw more than their rating will not damage the system but it will stop working instead, and quite often a safety device will operate.
Another effect is that a shaver socket cannot act as a replacement of an ordinary socket in the bathroom. The shaver is assigned a particular function just like that, and installation of a general-purpose socket there is a different matter altogether.Where a project needs a socket with modern charging capability as well as compliant safety, the options are a separate discussion, and the features and ratings involved are covered in our article on USB zidne utičnice i brzo punjenje.
The geographical span indicates most of the practical confusion.
BS 4573 shaver sockets can be found in Great Britain and Ireland and are used in bathrooms in peoples’ homes and hotels around the world.In several locations in Asia, the Middle East and Africa, several hotels use the shaver socket in combination with various other types of sockets to cater to the various types of traveling guests including the guests traveling with their shavers. The fact of the matter is that shaver sockets are nowadays widely used in many countries because of the high demand for their use together with other types of sockets even though BS 4573 standard is officially British.
Europlugs are available in a large number of countries in Europe that adopted the European socket standards, including Germany, Italy, France, Spain, Greece and others. Europlug is used mainly for low-power devices to be connected to the wall socket of Type F or E.
However, that is where the conflict comes from. As a British traveler comes to Spain, they discover that the socket there accepts a different type of plug. As a Europlug traveler comes to the UK, they also find out that their device cannot be plugged into the socket in the bathroom.
A plug or socket can easily be identified by four simple checks, and only the first one requires a little bit of effort.
The shaver symbol is the single most reliable indicator on a socket, because it is compulsory under both BS 4573 and BS EN 61558-2-5. A socket marked with that symbol is a shaver supply unit with an isolating transformer, whatever the physical hole pattern may suggest.
With adapters, the situation can be more complicated than with many other socket types, which is worth understanding.
A BS4573 shaver plug has its own socket type that will not match any other countries’ sockets and so needs an appropriate shaver plug adapter to work abroad. Such adapters do exist and can even accommodate a European Type C or a US Type A plug and, on rare occasions, even an Australian Type I plug. The unfortunate aspect of a shaver plug is that the large dimension of its pins as well as their distance from each other make it impossible to use it with most universal travel adapters – cheaper versions can slightly stretch to allow the plug go through, but in general, the rule is that the better-made the universal adapter is, the less likely it is to accept a British shaver plug or toothbrush plug.
For a person traveling abroad the easier solution is to buy a local electric appliance. A razor bought in Europe and from a European supplier you can be sure will have a standard Type C Europlug that allows it to be used both with local sockets and British shaver sockets, which means that no adapter is needed.
The same principle of reverse application is true for projects involving electrically driven devices. If it comes to having a shaver socket in a bathroom, this socket shall be considered a special shaver equipment that has a transforming energy device and is marked properly, and not just a regular socket with a shaver plate applied to it. The necessity of having the unit compatible with a Europlug or not is the issue of design; usually elongated contacts that allow for accepting both socket varieties shall be used.The specification detail that separates a compliant device from a lookalike is the same discipline that applies to any wiring device, and it is set out in our guide to choosing an electric switch and socket manufacturer.
Where a socket is being replaced rather than newly specified, the safe working sequence is the one used for any wiring device, covered in our article on zamenu svetlosnog prekidača.
And where the installation includes dimming or other controlled loads on the same circuit group, matching the device to the load follows the principles in our guide to ugradnja prekidača za prigušivanje.
Not in a straightforward way. The British BS 4573 electric shaver plug features 5.1-mm pins set 16.7 mm apart, whereas in a European socket the design is with 4-mm pins approximately 18.6 mm apart, which means that the shaver plug’s pins are too thick and too close for the socket. A separate plug adapter must be used because of this. The only exception is shaver supply units with long pin contacts that are designed specifically to accept both Euro plugs and BS 4573 plugs, however this is a characteristic of type of sockets but not of the standard.
The plug needed for low power devices like chargers, lamps and small gadgets is the Europlug (Type C, CEE 7/16), designed to work with Types C, E and F sockets in the rest of Europe. However, for appliances requiring more electricity — hair dryers, travel kettles, etc. — it is necessary to use either a Schuko (Type F) plug or the French (Type E) plug, since the Euro plug can only take 2.5 A. Travellers from the UK, Ireland, USA, Canada, Australia and New Zealand must use a travel adapter, as their plugs cannot fit the European plugs directly.
It is correct; and it is the same way in the United Kingdom. In order to allow them to be charged using the bathroom shaver outlet, British electric toothbrushes are shipped with the same BS 4573 two-pin plug as electric shavers. The current limit of the outlet is 200 mA, and it has a power rating between 20 VA and 50 VA, which is enough for it to be used as a toothbrush charger, but it is the use of the isolating transformer in the system that makes it safe to use near the sink. It is typical for European electric toothbrushes to come with a Europlug that may allow the appliance to be used with a shaver socket only if this socket is fitted with the dual elongated contacts.
From a physical point of view, it is possible to cut off the two-pronged plug in order to replace it with a domestic plug. However, there are two warning to take into account. First, appliances that come with a shaver plug are made to function with the unique supply of a shaver socket. That means that if it happens to get connected to a socket of a different type, its isolation will be removed. The importance of this issue largely depends on the type of the appliance, so the manufacturer should be consulted with prior to making any modifications. Second, whatever the new plug is, it’s essential for it to conform to standards and to be fused correctly.
Due to the characteristic of being dual voltage shaver supply units that provide 230 V and 115 V outputs. The 230 V output usually includes the use of BS 4573 shaver plugs, Europlugs, and Australian plugs on occasion, while the 115 V output would use a two pin NEMA type A plug for guests who might bring their equipment with them and do not require an extra transformer. The two outputs are available because of the design of the isolating transformer that can provide one of the two required voltages, which is the reason hotels use these devices.
A shaver socket differs from a European plug in several ways, which are very likely to deceive consumers. For instance, British shaver standards accept 5.1 mm of pin dimensions with 16.7 mm distance, thus limiting electricity usage up to 200 mA due to an isolating transformer. On the contrary, the Euro plug supports different pin size that is roughly 4 mm with the distance of 18.6 mm and electricity rating of up to 2.5 A. These two aforementioned aspects (one pertaining to dimensional differences while the second concerns electrical differences) account for many issues: shaver socket cannot run a hair dryer, while European devices that were bought locally operate in British sockets while British shaver sockets cannot fit Spanish wall plugs. Thus, the next piece of advice for travelers from engineers is to purchase their devices on the territory they intend to use them.
Although they seem to be alike, they both have a round shape with two pins, and they function at a voltage of 230V. This explains why some tourists use a European plug with a British shaver or wonder why a shaver cannot be plugged into a Schuko socket in a Spanish hotel. In reality, they […]
