National input voltage, frequency and plug types in various countries

Household power supply specifications will vary by region, but generally speaking, voltage values are usually between 100V and 240V, while the most common frequency values are 50Hz and 60Hz. Factories using polyphase power will have more differentiated power supplies with higher voltages and more specialized plugs and sockets for larger equipment, but will still use the general power supplies shown in the list to supply smaller equipment or general domestic facilities.

There are two main basic voltage and frequency standards in the world. One is North American 110-120 volts, 60 Hz, and uses type A and type B plugs. The North American national standard stipulates that the error range of power supply is −5% to +5%. The other uses the European standard of 220-240 volts and 50 Hz. The plugs used are from type C to type M. The allowable error range in European countries is −6% to +6%.

Canada A、B 120 V 3,4 120/208 V 60 Hz Usually 120 V and 240 V are used in high power consumption equipment (such as dryers and electric ovens). Buildings with multiple wiring can use both 120 V and 240 V, but 120 V is still the more common main voltage. Due to the regulation that new buildings should use type B, type A sockets are becoming less and less popular; at the same time, some kitchens will use a variant similar to type B but with a T-shaped socket.

Brazil A、B、C、I 110 V 3,4 220/380 V 60 Hz Dual-voltage wiring has begun to become popular in Brazil, and 110 V power supply areas have become common in I-type 220V sockets and electrical appliances. High-power-consuming equipment such as dryers have begun to use 220 V. However, depending on the region, there are several types of power supply: 110 V, 115 V, 127 V, 130 V, 220 V, and 240 V, and sometimes A, B, and C type plugs can be used (flat with rounder ends and ground pin) . Starting from 2009, Brazil will switch to J-type IEC 60906-1 plugs and sockets.

USA A、B 120 V 4 220 V 60 Hz The standard specification is 120 V, and the power supply is mostly between 114 and 126 V. 240 V/60 Hz is used for power-consuming facilities such as air conditioners, dryers, and electric ovens; buildings with multi-channel wiring can use 120 V and 240 V at the same time. It is stipulated that new or newly renovated buildings must switch to type B sockets, and sockets similar to type B but with T-shaped slots must be used in kitchens or places where electrical appliances higher than 120 are used.

Now the standard voltage is 220 V. 110 V was used in the past but has now been eliminated; some people still install their own voltage regulators to use the previous 110V electrical appliances. Most hotels only have 220 V sockets, and a few hotels have both 110 V (types A and B) and 220 V (types C and F). The sockets and switches are the same as those in the United States.
