Not if the cable is just two core they wouldn't. Or if the appliance is all insulated=Class 2.


Z.

Right, where you would have a double insulated tool, which is not capable of becoming live ie made of plastic. 

I think the issue Z is highlighting is that Class II products (and perhaps tools - but "live working" tools are not a measure for protection against shock etc. alone) is that they can get broken when being used. Under those circumstances, a single fault outside the provisions of the product standard (broken appliance casing, or damaged flexible cable, for example) exposes ordinary persons directly to live conductors ??

That would be an issue with the listing standard for the tool/appliance vs BS7671 needing to over reach into a product listing IMO. 


But I do get your point and I think there is where standards for appliances should be such that such a scenerio is not likely. Think of apple chargers that used to fall apart when unplugged- now they can not be torn apart by reverse engineering.
