Why do Europe and America have different outlets? Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper. At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly. And less current allows for thinner wires.
Why are American outlets different?
The reason why the world is now stuck with no less than 15 different styles of plugs and wall outlets, is because many countries preferred to develop a plug of their own, instead of adopting the US standard. Many Latin-American, African and Asian countries are still in the same situation that Brazil used to be in.
Can you use a European plug in the US?
How Can I Use a European Device in America? If you've bought a device or appliance from Europe, don't try to use it without a voltage adapter. Since European devices use 220 volts, and US outlets run at 110, running the device on a lower voltage can damage the device.
Why do UK sockets have switches?
To save copper, Britain adopted the ring main system, with sockets connected sequentially, but this meant each connection needed its own fuse. Instead of putting the fuses in the sockets, they were included in the plugs themselves. Hence the UK's bigger plugs.
Are European outlets different?
All of Europe operates on the same 2 round pronged outlets except for the UK and Ireland that operates on its own unique 3 flat rectangle pronged outlets.

Why do hair dryers not need an earth wire?
Appliances encased in an insulating plastic case or body, such as hair dryers, mobile phone chargers and hand whisks do not need an Earth wire. Such appliance are designed so that there are two levels of insulating material between the electrical parts of the appliance and any parts on the outside that can be touched.
How do I convert European outlets to American?
To rewire a European plug to work in the US, remove the cover of the European plug. Then loosen the 3 terminal screws. Insert the ground wire into the connector hole and tighten the screw. Then take the neutral wire and put it into the neutral connector hole and tighten the screw.
What country uses DC power?
Electric Current Information for All Countries

| Argentina | All | a.c. |
| Argentina | All | d.c. |
| Armenia | All |
Does Europe need voltage converter to USA?
- Most electronic devices have a 110v-220v transformer or dual voltage (110/220 VAC) for worldwide use. If your devices have it, all you have to do is simply plug this adapter and you can use it in the USA.
Why do New Zealand outlets have switches?
Electricity and voltage in New Zealand
In New Zealand, the outlets have switches on them so you can leave the piece of equipment plugged in but switch off the surge of electricity. Contrary to the US, the switch is down which means it is “ON”. Switching off the lights when you're not using them.
Why are UK plugs safer?
Prong Design: Like standard U.S. grounded plugs, the U.K. wall plug has three prongs. Although the built-in fuse adds bulk to the U.K. plug design, it's also safer: In case of an unexpected electrical surge, the fuse simply blows and the electricity shuts off, preventing fires, electrocutions, and other accidents.
Why are there 3 wires in a plug?
The plug contains three wires – the live, neutral and earth wires. The earth wire (green and yellow) does not normally form part of the circuit and is included as a safety wire. It is connected to 'earth', which is usually a large metal spike buried under a house.
Are European outlets grounded?
In fact, most plug types used in Europe are not polarized. Continental European cord sets are available in three stocked cable sizes. Depending on cable used the cords and cord sets are rated for service between 2.5–16 amps at 250 VAC. However, the Continental European plug will not be grounded .
Why is US 110V and Europe 220v?
Once AC was widely accepted as being superior to DC for power distribution, 110V became the standard for AC distribution presumably because it used the "safer" Voltage level of the DC system. After metal filament lamps became feasible, 220V became common in Europe because of the lower distribution costs.
Why does America have lower voltage?
To answer the question, though—the US does have a higher power supply. Nearly all homes in the US have 240V alternating current lines at the service entrance to the household as well as select locations within the home. The reason it's 240V is because that's the power line that has been standardized over here.
Why do American plugs have holes?
These bumps fit into the holes so that the outlet can grip the plug's prongs more firmly. This detenting prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet.
Why do sockets have 2 earth terminals?
The reason your sockets have two earth terminals, is so as to provide high integrity earth terminations for use in circuits where high earth leakage currents are expected. There's nothing to prevent you using such sockets for normal circuits, and just using one terminal.
What plugs are in Australia?

| Azores | India | B,C,F |
| Bahamas | United States | A,B |
Is neutral safe to touch?
5 Answers. The neutral is NOT safe to touch. When everything is working correctly, it should be at most a few volts from ground. This is why modern appliances either have two prongs and everything is insulated from the user, or three prongs and anything conductive the user can touch is connected to ground.
What appliances can use a two core cable?
Two core flex: This type of cable is used for wiring light fittings with plastic lamp holders which do not require an earth. The cable only has two cores being live and neutral. As this is flex cable it will be of circular shape with an outer sheath and two colour coded PVC insulated cores.
What is a 230v outlet?
A 230-volt air conditioner uses a specialized outlet, much like the type that a clothes dryer uses. This outlet must be professionally installed up to your local electrical codes, and you must figure in the cost to do into the overall price and convenience of the 230-volt air conditioner.
