From Wiring Matters
It is good to see John Madden calling for a British Standard for socket covers (letter in issue 45 of Wiring Matters; see also www.shocked.org. uk). Regulation is also the subject of an e-petition started by Trevor Ord and supported by FatallyFlawed.
Mr Madden raises a number of issues deserving further examination. He refers to the evidence he gave to the Fatal Accident Inquiry into the tragic death of Liam Boyle, killed as a result of having access to a cable with exposed conductors. The Sheriff’s determination in this case is online in the public domain, and is worth studying.
The idea that plug-in socket covers reliably prevent children from plugging in dangerous appliances is not based on research or fact, but on wishful thinking.
A BS 1363 plug is secured in a socket solely by force exerted on the pins by the socket contacts. The only way that a cover can legitimately be made difficult to remove is to ensure that it is impossible to grip it.
