And of course 90+% of UK persons are right handed.

I suppose that makes sense for the old lever switches - and they just carried on.

 

[JohnW2]

Yes, on the ones that do would you put it the opposite side and connect live into neutral and vice versa?

Indeed, and I think you could do that with virtually all makes if CU that had a 'standard/traditional' busbar layout. Despite what you seemed to imply, I see nothing special about Fusebox.

Don't know if it could do it

Although obviously electrically fine, I imagine that many/most of us would feel a bit uncomfortable doing it - and it would, of course, invoke the risk of a C2 from an incompetent EICR inspector

I liked to old CUs with the main switch in the middle

 

[JohnW2]

I never understood why the main switch started being placed on the left when they had always been on the right.

A substantial proportion, I would think probably a significant majority, are still on the right, aren't they?

I think it might be to suit a majority type of thing. If you manufacture for all of Europe and beyond then you are unlikely to cater specifically for the UK and a few more , it makes manufacturing sense to cater for the majority only in such situations whether or not common sense is common or uncommon sometimes. Also you need to decide which terminal to be N and Which to be L and how that fits your busbar design too. And if you have the N switch to lag/lead the L switch or whether to be always simultaneously. The Wylex of old compared to their “new” Red Rocker down for off might be such an example - was it to make a potential convention usually safer or to suit a majority?

That could be directed at anyone, but if its directed to me, and my most recent post, then yes, I had read all the posts, but was indicating that the TLC photo (in which we can't see L&N markings, probably because of poor picture quality) is the identical product (IT1002) to the one shown on the Fusebox website (which I posted here earlier) in which the markings are cleanly visible.

...And if you have the N switch to lag/lead the L switch or whether to be always simultaneously.

Although I (and others, like EFLI) have been saying or implying that the 'polarity' of the switch does not matter, we had overlooked the fact that one side might be designed to make (and/or break) first. Does anyone know whether this is true of any CU 'Main Switches'?

I did not say nor imply that the polarity did not matter nor should be ignored.

If a switch can be fitted on the other side then obviously it is either made the other way round or the polarity doesn't matter and won't be marked.

You may not have used those exact words, but you seemed to get might close to the spirit of them when you wrote ...

Both sides of the switch are the same - well, mirror image. .... It won't have 'L' and 'N' markings. Why do the ones that do?

... didn't you ?

If a switch can be fitted on the other side then obviously it is either made the other way round or the polarity doesn't matter and won't be marked.

Yes, but that's a big IF - I don't recall seeing any comment in MIs about what side a switch should be fitted, do you?

... and the corollary of what you've just written would seem to be that if there are L&N markings, then this means that polarity does matter. Do you really believe that? (as I've recently written, I don't think either of us had really considered the possibility of a designed 'order' of making/breaking)

No.

Yes, some of them have 'L' and 'N' marked on them.

... and the corollary of what you've just written would seem to be that if there are L&N markings, then this means that polarity does matter.

Duh!

Do you really believe that?

Of course.

(as I've recently written, I don't think either of us had really considered the possibility of a designed 'order' of making/breaking)

I have heard it mentioned before but It doesn't really matter what the reason is, does it.

Do you think the manufacturers mark the switches for no reason?


D'oh! You have drawn me in again to your ever-expanding questions.

MK.

Yes, and the MK CUs always had the main switch on the left (mine has). The new ones do too.

I mentioned about Fusebox having Main Switch position flexibilty because I am sure that I read it somewhere.
I will ask Fusebox support and get back to you all.

It wouldn't surprise me.

D'oh! You have drawn me in again to your ever-expanding questions.

I think you did most of the 'drawing in', but I haven't got time to play games at the moment (it's that time of year ), so maybe 'in due course' !

Oh, was it you?! I recently accused pete of having made that statement ... sorry, pete!
