Recently, a sample of an IEC power cord was sent to me by Gerald Ruane of Ashdale Electrical Testing. This was following a Linkedin discussion started by Patrick Maher of PAT's Testing Swindon. Below is a report on this highly dangerous lead.
I tested this lead on a PAT Tester and it failed Earth Continuity - it was off the scale. I checked Earth Continuity on aMilli-ohm meter and it was reading around 0.15 ohms. It was only when I took a close look at the plug that I realised the reason for this. Have a close look at the photograph below.
The result is that someone using this on a Class 1 appliance will not have any Earth protection at all, making the use of this lead highly dangerous.
Digging round on the internet, I came across the following links which readers of this blog may find interesting.
Brief note regarding insulated earth pins.
This is a very interesting feature on counterfeit plugs which includes examples of insulation on Earth pin, inadequate cable rating and plugs with no fuses. Well worth a read.
The image below shows the marking on the plug more clearly.
