Perhaps - but, as I said, when the vast majority of people use one term and a tiny minority use the other, one might at least wonder about the logic of the latter being being regarded as the 'correct' one.Yes, maybe, but wouldn't it be better if everyone knew the correct terms - or rather had not learnt the incorrect terms.
If, as you seem to believe, the dichotomy between 'everyday terminology' and 'technical terminology' should not exist, then surely your only hope would be to cut of the everyday version 'in the bud', since it's clearly far too late by the time that most people are using it?
Worse, in my opinion, are cases like the lamp/bulb situation - since "bulb" was in universal use before someone took it upon themselves to try to instigate a 'change' (even if well-intentioned, since many bulbs no longer looked like bulbs!). That was, to my mind, far worse than 'too late' - perhaps witness the fact that a high proportion of the general public (and others!) seem to have ignored the 'change'.
I think it remains the case that if you ask in almost any retail store to be directed to "the lamps", you'll either be sent to the wrong place (for 'bulbs') or told that they don't have them (even if they clearly do!) - and, similarly, if you ask for 'a lamp for your lamp/bicycle/car/fridge/whatever' you'll either get some very funny looks or be shown/given the wrong thing!
I suppose that would be for those (very few) who deal with such voltages to decide. For some reason, "MV" disappeared. As I said, I would think that around 500V would be a reasonable cut-off between "high voltage" (per 'lay' usage) and "higher voltage" (whatever calle), since that's roughly the dividing line between what is encountered by those involved with domestic/commercial (and much industrial) installations and those ('the few') involved with generation and distribution.If 240V is high voltage; what is 33,000V?
I think that one is perhaps in a different league since, as you say, it is plain wrong even in terms of technical terminology - so I certainly do agree that that one really should be 'corrected'!Anyway, there is no hope when manufacturers make GU5.3 lamps and call it MR16 - even when the lamp itself is not even MR16.
I'd love to know how that one ever came about!I'll get you onside by mentioning 'plugtops'.
