While cleaning out the SimplyPats cupboards today I came across an IEC lead that we had, I thought it has been supplied with a new PC, however the guys tell me that it came with an external hard drive caddy.

I asked Carl to take a photo of it next to a proper plug top.

There are no manufacturer's markings on it, however given the multiple faults I'm not suprised. I'm no expert however we listed 3 visually identifiable faults:

1) Plastic insulattion on the earth pin.
2) Fuse?
3) Distance between edge of plug and live and neutral pins is very small.

At this point we decided to PAT test the IEC lead using a Metrel Sigma PAT and then a Megger PAT DV3.

1) Earth continuity >19.99 Ohms - so no Earth
2) Polarity test on the SigmaPat said Multiple Faults

The IEC end has 10 Amp stamped on it, and the cable felt extremely thin, so finally we stripped the conductors to see whether there was anything inside.

1) Interesting colour scheme used for the conductors.
2) The conductors were amazingly thin.


There are no markings on the plug or socket to suggest who and where it was manufactured however the cable has printed on it:

TH PVC INSULATED COPPER WIRE & CABLE
