"kreed"
I do see what you mean, 2 different types of cords, and there is a recall on both types.
** No - there is a recall on the products.
Only faults I can think of that would be hazardous, but the gear would still work would be no earth connection at the plug,
** You said that already.
or earth and neutral both connected to the neutral pin,
** Still trips ELCBs in a moment.
as it says "plug may have been wired incorrectly" and "rewire the mains plug if faulty"
** Wrong to take that literally.
It was written by some moron in marketing you know.
The units could have come from China (or where ever they are made) with the Australian plugs wired by hand there too.
** I have not seen a hand wired plug on anything from Asia in decades
If they didn't have sufficient ready made cords, they may have hand wired a few plugs onto existing ones to get the shipment ready to deadline.
** IEC leads are prescribed items, each component must be approved ( and labelled with the approval code number) for use in Australia - you cannot just dodgy one up from bits.
Moulded ones with Aussie plugs ( same as China) cost tiny amounts compared to paying someone to modify one with the wrong plug.
