This looks like another case of a bad termination leading to overheating, followed by crispy despair.

Live A Little

without comments

Pulled out some live cables from an otherwise isolated light-switch. This is why it’s best to assume everything is live until you can prove it’s dead.

It is considered good practice to put any cut off cables into connector blocks. It is better to remove them entirely.

Colour Me Surprised

As far as I can figure out, this is American/Canadian cable, where black = ‘hot/live’, white = ‘neutral’ and green =earth.

Fatally Flawed – Socket Covers Are Dangerous

with one comment

In the list of things that new parents, careworkers or teachers have to think about, electrical safety is pretty near the top.

Socket covers are a commonly accepted way of making sure children don’t poke their fingers or objects into places that might be dangerous to them. However, sockets have already been designed with safety in mind, and have internal shutters that ensure foreign objects cannot be pushed in. The shutters either release on entry of an earth pin, or on pressure from all three pins of a plug.

It is possible to insert some ‘safety socket covers’ upside down, thus opening the shutters to allow access to live parts. Other socket covers leave gaps that small thin items like paper clips can be poked in. Others can be easily snapped. The plastic pins on most of the covers are not long enough to ensure they have a good grip.

Though there might be a benefit to stopping children from plugging in other appliances, without proper design and regulation, the current range of socket covers are not safe.

There is an online campaign calling for regulation of socket covers that is essential reading: http://www.fatallyflawed.org.uk/

In The Drink

Placing a socket so close to the sink would generally be considered a bad idea.

The ECA website says: “BS 7671 does not specify any minimum distance for socket-outlets to be from a sink. However, regulation 512.2.1 requires external influences to be considered when selecting equipment for a particular location.¬†Accessories used in domestic installations are not designed to be splashed and therefore not suitable for installation close to a sink or draining board. For this reason, it is recommended that socket-outlets and other accessories should be located at least 300 mm, measured horizontally, from a sink or draining board, where they are less likely to¬†get splashed.”
