When FatallyFlawed was founded our only concern was that socket covers, because they are invariably badly designed, can be used to defeat the shutters in a UK socket. But, the more we looked at the problem the more we realised that there are a number of other serious problems with them.
The biggest issue is actually the permanent damage which can be caused to a socket by the insertion of anything which is not the right size, and one thing that can be proved irrefutable by anyone who measures a socket cover is that there are NONE which conform to the size and shape specified for a plug.
It is very clear that the people who "design" socket covers have only a vague idea how sockets work. It is very important to understand that a socket is always designed to accept a standard plug, plugs are not designed to fit sockets. This means that anything which is not the exact size and shape specified for plug pins can create problems. This simple fact seems unknown to those who make socket covers!
Some socket covers can damage the electrical contacts of a socket, this will not matter as long as you do not actually use the socket, but it can result in overheating and cause a fire when the socket is again used to deliver power. Of course, you can only use the socket if the socket cover is removed, therefore it is never apparent that the root cause of an electrical fire was the socket cover that damaged the socket. It can be that a socket which has had a cover left in it for a long time may not actually be used until the house has passed to a new occupier.
Another way in which socket covers can cause damage is to the shutters. People often think that shutters are operated only by the insertion of the earth pin, and while that is the most common method, there are actually at least seven different (legitimate) methods in use. One type of high quality socket, which was made in huge numbers from the late 50s to the late 90s, does not rely on the earth pin at all, but simultaneous insertion of the other two pins. The best sockets available today, from several different manufacturers, use sophisticated shutter systems which will only open if all three pins are inserted simultaneously. It is these, the safest sockets available, which may be broken by forcing in wrongly sized covers, especially the Clippasafe type.
The problem is that socket covers are totally unregulated, there is no standard to which they must conform, standards are not normally created for products which have no genuine use! The Minister responsible for consumer protection, Jo Swinson (herself a new mum), claims that the General Product Safety Regulations can be used to tackle the problem of socket covers. However, the people whose job it is to protect us from dangerous products, Trading Standards Officers, have found that in the absence of a standard for socket covers there is nothing they can do.
Despite Trading Standards having confirmed that for 28 socket covers recently tested "in all cases the size and disposition of the socket cover pins were not compliant with BS 1363-3:1995 (the standard for plugs)", there was no remedy available to them.
In the words of Mark Coles, the man responsible for the UK Wiring Regulations: "Socket protectors are not regulated for safety, therefore, using a non-standard system to protect a long established safe system is not sensible.”
And from the leading British socket manufacturer: "MK goes to great lengths to ensure that all its BS 1363 plugs and sockets are safe. Inserting incorrectly dimensioned products into a socket-outlet can both damage the socket and reduce its safety.”
I wonder what qualifications designerdad and TrendStopper have that makes them believe they know better? Perhaps they will explain?
