Re: Plug cable entry angle
Yes, that IEC 60906-1 plug/socket was exactly the sort of thing I was thinking of.
It it was fused, it would seem pretty much ideal.
(Straight cables are a definite plus for me in two ways:
1. Not a caltrop.
2. If you trip over a power cable and it yanks the plug out, that means you had a power cable in a stupid place, acting as a trip hazard. A right-angled plug is a hack, rather than a proper solution to that problem.)
