Dangers of Electrical Faults

Dangers of Electrical Faults

Electrical faults can take many forms, from the minor irritant to the serious and life threatening. They can appear gradually over time as a result of wear and tear and deterioration or suddenly as a result of changes made accidentally or deliberately through lack of knowledge or competence.

Most minor faults won't be dangerous but could prevent circuits from working as they should - so you know there is a fault - like a light, socket or appliance. Of more concern are those that could be dangerous if they are left to get worse.

Take a look at these simple visual checks that could save you and your families’ lives.

Millions of people in the UK expose themselves and their families to potentially fatal electrical accidents in the home by making simple blunders, down to a lack of knowledge about the dangers of electricity.

It is important to make sure that the electrical installation in your property is well maintained, and we recommend that you use a registered electrician to check that it is safe.

However, there are a number of simple, visual checks that you can carry out yourself:

Electrical Fails - Melting plugs

Melting plugs and sheaths on wires happen more often than you might realise.

Poorly terminated wires explain some of them but more often it is due to DIY  installations combined with excessive loads being used on the socket.

The first melted plug was connected via a long extension to an outbuiding where the small Consumer unit pitcured was wired directly to it. Multiple freezers were running from it. This really was a fire waiting to happen.

The outdoor socket in the third image shows the sheath melting from the temperatures being reached in the copper cable. The sockets were being used to power extension leads running various outdoor heaters. Again luck was all that had prevented a fire.

Look at the socket calculator here to check whether you're over stressing your cabling and sockets.

Electrical Fails - Outdoor Power

We were told that the lighting for the garden hadn't worked for a long time and the pump for a similar time. Can we take a look.

This is what we found shortly after arriving - granted it was under a car port which was watertight but still...

An indoor fused control unit (FCU) with SWA - the thick black cable - which had been terminated but was hanging from the terminations in the FCU. Various other electrical connections had been attempted unsuccessfully.

Everything was taken out and made safe to be re-installed properly at a later date.
