Why do American outlets not have switches?

Why do British bathrooms not have sockets?

Because the rules about domestic power in the UK are some of the safest in the world (partly because we use 240V which has a higher risk of death) and having power outlets in a bathroom, particularly on an earthed system like the UK uses, is very risky, as people will plug things in which shouldn’t be used when wet; …

Are US power plugs the same as Australia?

Voltage Converters

Mains voltage in Australia is 230V 50Hz. Travellers from most nations in Asia, Africa and Europe should have appliances that work on the same mains voltage as Australia – therefore you will not need a voltage converter. Notable exceptions to this are Japan, USA and Canada which uses 100/120V 50/60Hz.

Are US plugs fused?

Electrical plugs contain fuses to protect appliances and their cables and reduce fire risk. Fuses do this by breaking the electrical circuit in the event of excess current flow. But fuses are only normal in British plugs (also used in Ireland and a handful of other countries).

The logic behind that number is that an appliance with a standard length cord could then be plugged-in anywhere along the wall.
