We are going off-piste here but since you own this thread, ...

Unlike the US wiring system where each wall socket is star wired to the distribution board and protected by a circuit breaker, the UK wires large groups of wall sockets in a "Ring"; and protects the Ring with a 32A Circuit Breaker.
So besides our Voltage being 230V (compared with the US 110V), each Socket will deliver 32A continuously before the Breaker even thinks about tripping. That is 7360Watts which is about the total heat put out by your Kitchen Stove with the Ovens and ALL Rings at full pelt. However, this design is complemented by a Socket and Plug design which protects everything downstream of the Wall Socket by:
* Designing the Socket with the Earth Pin triangulated at the top and longer than the other two pins so that a foreign object dropped onto the pins cannot lodge itself between the Line and Neutral or Line and Ground Pins. The Earth Pin also actuates the shutter in the Socket which prevents objects being poked into the Line and Neutral sockets.
* Protecting everything downstream of the Line Pin of the Plug by building a replaceable High Rupture Capacity Fuse into the Plug right at the head of the Line Pin. The Fuse rating is suited to the current carrying capacity of the cable (or whatever) connected to the Line Pin of the Plug.
* Making it illegal to supply an appliance in the UK which does not have a Moulded Plug with integral fuse matched to the cable. Thus the IEC (Kettle Cable) has two versions, a 13A with a notch between the Line and Neutral pins, and a 6A version commonly used with computer equipment .. with no notch. Plugs fitted to light appliances such as table lamps, Shavers etc can have 2A, 3A or 5A HRC fuses fitted.
Now, you can buy cheap adapters on eBay, which don't have an integral fuse but you will NOT find these in the shops or Airport stalls here because they are illegal. Look for one like this 13 Amp Shaver Adaptor to BS1363 Fitted with 1 amp fuse: Amazon.co.uk: Garden & Outdoors
If you think my answer is verbose, I would refer you to the Seventeenth Edition of the Institution of Electrical Engineers Regulations which covers this subject in greater depth
