so referencing the install guide:
Well yes, you could have any voltage. So why specifically 415/230V ?
Manual page 1-6 is very clear about what supply systems are allowed and disallowed. It doesn't mention 415Y/240V, but since corner grounded 240V delta is disallowed, 415Y/240V would also not work.
You could, but you'd need 3 such transformers and distribution boards. Same as with winnie's #6.
wayne,
thank you sir
Because the voltage to the power supplies would be similar to what is found in other countries, for consistency in protection and operation designs.
Actually most of the world is 400V or 380V. Europe is nominally 400V/230V 50Hz.
Hooking up a 400 volt machine today. They provided a transformer to step up the 230 to 400. I believe it was made in Italy.
Mostly we used straight 400Vac, no transformer. That was industrial in my case. Residential was all 230Vac.
We don’t have 400 vac in the states, so we have to step it up or down.
Yes, indeed. You have 460V/60Hz as a rule so why would you need 415V?

Well, sometimes we Brits get it right. Slight digression. For most of Europe (including UK) we use the SI system. Now and again we stroll over to our local pub. I enjoy a beer and my wife has a glass of wine. My beer is one Imperial pint. My wife has a 250 litre of red wine. Bit quirky I suppose.@jim dungar answered this in post 15 and 27.
We have 480/277V for high power loads such as motors and HVAC. We have 208/120V for most office use. We have 120/240V for single phase residential use. We don't _need_ anything else.
415/240V is becoming more common as yet another system to confuse people because you guys got it right across the pond
Seriously, most computer power supplies are specified to work with up to 240V L-N, and by operating at that voltage you get maximum power density in your power distribution system (panelboards, etc.) So 415/240V is used because it is the highest voltage which can be used with off the shelf computer hardware, and that is the case because it is so commonly used around the world.
If these power supplies were commonly available to work on a nominal 277V L-N (including the maximum allowed variation) system, that is what would be used.

I sure hope that is 250 millilitres, unless you mean those teeny tiny imperial liters
Silly me!I sure hope that is 250 millilitres, unless you mean those teeny tiny imperial liters
That sounds like someone who has no clue. I cannot believe that they would make a charger that would not work in literally 80% of the countries in the world...
These EVSEs may be North America specific models. Or it may be that they would work elsewhere with a firmware modification to disable the minimum 80V L-N monitoring, see post #23.
