It seems as though it's not just imported equipment being fitted with polarized plugs where they're not really needed.
I have a recent-ish Dremel (120V American-market version) and it has a polarized plug. The tool is made in U.S.A., although I suppose the cordset might have been imported. It's double-insulated with black and white cores rather than SPT type, so are polarized plugs being used on all such identified cordsets now?
just out of curiosity in Ireland I notice a lot of burn damage around the live receptical of sockets, including well known brands like MK ! Also notice it around the live pin on plugs of heavy appliences quite a lot.
I see it a fair bit here too. Some of the cheap BS1363 plugs can get very hot under heavy load, and as you say it seems to be the fuse and clips which cause the problem.
I advise people to use those "el cheapo" plugs on their bedside lamps, radios, etc. if they wish, but recommend a better make such as MK for the washing machine, tumble dryer, heaters, etc.
Schuko plugs have one more advantage only a recessed system can offer: They hide any arcing from the user.
Most people here would probably argue that visible arcing shouldn't be a problem due to the majority of outlets have integral switches.
Switched receptacles are so much the norm here that some people are under the impression that the regulations require them, at least in domestic work. The only time the IEE Regs. specified an integral or adjacent switch for general purpose outlets was on DC systems.
