Why are there different types of sockets?

So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years. Now that most homes in the world have access to electricity, adopting one global standard would be more convenient than having different types of plugs.

Are plug sockets without switches legal?

2 Answers from MyBuilder Electricians

Un-switched sockets are not illegal and are used for powering appliances that should not be switched off externally like Fridge/freezers and so on.

Do sockets have to have switches?

Unswitched sockets are quite common on older installations, but are still permitted to be used under the current regulations (BS7671:2008). However switched sockets are much more practical and safer, as the switch can be used to isolate equipment as opposed to physically unplugging it every time.

What does Unswitched socket mean?

Switched outlets repond to the power switch. Unswitched outlets do not respond to the power switch – they are always on while the power strip is plugged in.

Why do British power outlets have switches?

The reason plugs in the UK are so big is that each one must be individually fused. And the reason for that is something called a “ring circuit”. In a ring circuit you have, say, a 40 amp fuse at the mains/box. … Ring circuits have serious drawbacks, but they helped during a time when there was a copper shortage.

Why do UK plug 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 plug sockets with USB ports safe?

USB wall sockets installed in homes and other private locations will transfer data in the same way, but are much less open to being compromised and so are generally safe to use.

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.

What is the advantage of having a switched circuit instead of an Unswitched circuit?

The advantage of using circuit switching is that it provides for continuous transfer without the overhead associated with packets, making maximal use of available bandwidth for that communication.

What are BA sockets?

BA (British Association) screw thread sizes cover a range of small screw thread, originally being specified at the end of the nineteenth century as the British standard fastener for small electrical devices and scientific equipment. The design of the BA thread profile lends itself to low-torque applications.
