There is a very interesting Youtube Video British Plugs Are Better Than All Other Plugs, And Here's Why that indicates some engineering reasons why the British power plug is safer than for example the American style power plug.
As you can see in the video there are a variety of features that ought to make the British plugs safer than American and other plugs, including:
- the powered slots are shuttered until opened by a third safety-pin
- the pins are covered partway down by an insulator so you cannot touch the metal pins when they are connected
- the plug has an independent fuse
- the internal wires are colour-labeled "bLue" for Left and "bRown" for Right
- the grounding wire is longer than the powered wires (so if the cable is yanked out the ground should be the last thing to disconnect)
- The distance from pins to edge of plug is large to reduce risk of fingers getting near pins.
- The cable exits at 90 degrees so that pulling the cable is less likely to pull the plug partially out.
- The ground pin is longer so last to unplug.
- It is part of a system that has switches on outlets so that appliances can be turned off at the wall (rather than leaving unplugged plugs lying on the floor).
- The fuse is located so you have to unplug before changing.
- cables are clamped by a cord-grip
Do these interesting and seemingly important engineering feats bear out in reality? Has anyone any got any statistics on the number of deaths and injuries from electrical plugs in Britain, and compared them to other areas that do not have these safety features in their power plugs?
