... a good quality IEC female connector and plug like in pic below
I was using a lead with a plug very much like the one in your pic yesterday, and, unusually, it was not moulded on...
...So I opened it up and guess what I found!
Actually, it is a rather neat 2-pin -> UK-3-pin permanent adapter, and I wouldn't mind having a few, but have never seen such a thing on sale.
It may be the last vestiges of mother-country patriotism, but I do like the British (also used in Singapore) plug system. However, it must be plugged into a British-style "13-amp" socket: I have had bad experiences with the "international" sockets here, even though MK brand. If not actually British/Singapore origin, it is better to use the Indian 16-amp round-pin system for better grip and better contact
Although simple, it comes with an absolute life-and-death safety requirement to know what you are doing. But actually...
... running cables through conduits, over suspended ceilings, under raised floors, etc is, in practice, not very simple. The professionals do it in minutes.
... wiring IEC connectors is my least-favourite electrical job. There is no spare space inside, so the conductors have to be cut/stripped exactly right.
