only for the uneducated consumer. Go look up the UPS specs in a data center. Or the output of a stay live circuit on a PV system that works when the grid goes down. Systems have to be specced with a minimum, maximum, and nominal voltage.
In the US nominal is 120v and 240v and has been since the 1900s. Just because some uneducated consumer says it's 220v doesn't mean it's OK to put out 220v here. We have standards.
Well yes, the standards are there for the uneducated customer, so he/she can be safe and "dumb" and not worry about it.
Normal people call it different thing, depending on where and when they are from.
I don't need to go and look up ups centers, work alot with electronics, and we often use a ups as a "filter" for supply on different things.
Each country will have a similar standard and you can't just go around spitting out whatever voltage the locals call it and ignore those standards.
That's correct, but this is hairsplitting, rule of thumb in Norway and CE marked equipment is 10%, that would mean that everything from 207V to 253V, it's okay.
So, does it matter if you call it 220V or 230V?
-heck, you can even call it 207V and still be inside the norm...
If you need a "cleaner" power supply, use a "filter", that's the reality of things.
However, by arguing with the voltage of it, you completely ignored the different systems as I wrote earlier, there are a few differences in both null line and other things. But for a normal consumer, these things don't matter, for them it's still a 220V supply.
So as long as they can deliver around 230V ac, all approved electrical consumer goods will work.
How things are in Canada, I don't know, but here in EU / Scandinavia, it will work on 220v.
