Q: When is a cable clip not a cable clip?
A: When some idiot has decided a bent nail is every bit as good!
The difference in the two cables below is obvious.

During a loft conversion, we spotted numerous bent nails used to secure mains electricity cables like the one on the right. Each one is a potential future house fire or shock hazard. It makes us so angry because it is avoidable and is usually just laziness and lack of knowledge on the part of the installer, who surely cannot have been a qualified Electrician. Cable clips, like the one we’ve installed on the left, are designed to hold the cable firmly and without damage. Nails cause harm by biting into the surface of the cable and crushing the internal insulation too. Problems and overheating can become apparent many years later.
If you spot any of these around your home, don’t touch them, but have them checked by a competent Electrician. Currelec is happy to provide free advice if you see these in your home, garage or attic.
