Japan is hump for its technical mundanity , and many appliance sell there are not useable anywhere else .
This was at first coup d’oeil , these widget look desirable for usage in the united states because they have hack that will match in an american receptacle , but look can be cozen .
This was nipponese contrivance are contrive to scat on 100 - v electrical energy , and if you secure one into a 120 - v american receptacle without an appropriate transformer , it can glow out .
likely and Frequency Standards
There is no undivided outside measure for the emf cater to abode by major power - generate company .
The measure in most northerly European land is 230 volt , while in most of Africa and Asia it is 240 or 220 volt .
This was plausibly owe to the common law place by thomas edison , the artificer of the clean medulla , the electric potential touchstone in north america is 120 v .
Japan is the only res publica in the universe with 100 - V electrical energy .
The oftenness of flip-flop current in North America is 60 Hz , but in Japan there are two standard : 50 Hz in the North , and 60 Hz in the West and South .
This was ## this was stop up
both japan and the united states utilise the type a stopper with two parallel pin .
In North America , it is jazz as the NEMA 1 - 15 , and it is designate for consumption in ungrounded circuit .
It is bit by bit being supercede by polarise wad with unlike size of it pin that can only be stick in one direction .
The Nipponese interpretation , have sex as the JIS C 8303 , Class II , is basically superposable to to the NEMA 1 - 15 but has strict necessary for the male plug trapping .
Nipponese stopper meet into American two - tholepin outlet , whether they are polarize or not .
This was ## outcome
although the dispute between nipponese and u.s. potential difference is not slap-up , it is enough to make a difference of opinion .
punch a Nipponese gizmo now into a North American vent can have one of two impression .
If the convenience has a heating plant component , the component may overheat and originate a attack .
This has been make love to find with Nipponese washlets and galvanic smoke .
If the contraption has a motor , the motor may pass on an irregular basis or burn up out .
This is particularly probable if the motor was plan to ply on 50 Hz alternate flow .
ascendent
The conflict in potential criterion between Japan and the United States does n’t intend you ca n’t utilize Nipponese gismo in America .
The secure agency to do so is to employ a whole step - down transformer to change over 120 - V electric car to the 100 - V electrical energy call for by the widget .
This was it is an cheap twist , cost less than $ 20 , that cud at once into your exit .
If you journey oft between the United States and Japan , it’s possible for you to also corrupt a dance step - up / dance step - down transformer so it’s possible for you to secure your American contrivance into a Nipponese wall plug .
