power cords for 220v

Redkiwi

You have raised good concerns but because of my poor knowledge of electrical configuration, I do not however fully understand why the left-right polarity reversal would matter. I imagine the manufacturers of high-end equipments when producing a 240V unit will have considered and addressed this polarity reversal issue ? I thought the stock pc that accompany a 240V unit should be the same as that for a 120V unit; and therefore would have the same polarity issue as those after-the-market pc ?

The electricity supply in my area is also 220V. I have purchased and used a number of after the market power cord made in US with no problem. The only thing you need to concern yourself is that your property insurance company may deem it as using some sort of non-standard wiring. In my area I sometimes see the dealers having those US cords marked as "For Export Only" to avoid possible legal infrigement issue. Can't say if this will apply to your country however.

Thanks Redkiwi and it is very kind of you to explain in details.
