Let's go over how we got here. Harper posted this HNQ answer which says (in part)
Do you follow any of the warnings we give around here about the danger of 3-prong (groundless) range receptacles... and you think "Why does a 240V oven need 120V?"
The oven light.
That's right. The dangerous setup is solely so consumers can use ANY random 120V incandescent bulb they buy by the dozen (back in the day when everyone used incandescents and they were four for a buck).
After all, if we were going to make consumers buy special bulbs for ovens, we could just make them 240V bulbs, and then dispense with that darned neutral wire!
It's ranty about oven bulbs but... it still answers the question. There were some folks who didn't like it and commented about it, but then it descended into this
Ovens use ordinary 240V bulbs, just like every other appliance. What you're describing is only an issue in low-voltage parts of the world...
My oven runs at 230V, like the rest of my house. The bulb is 230V. Don't stick a 120V bulb in an oven unless you've got an oven that runs at low voltages.
This prompts some comments as well (this isn't about the comment chain per se) but what caught my eye is this comment from the questioner
I am indeed in the United States. Am I supposed to indicate that in some way in the question? There are a lot of ugly Americans, and I try not to be one of them. In this case I didn't even realize that the voltage of the oven has anything to do with the lightbulb I would need, so I wouldn't have known to even mention my voltage, much less assume it was the same elsewhere.
I'm not going to ask if the comments were OK, because they weren't (and I hope they're all gone soon), but I do want to ask about this. The community at large made the poster feel like they had done something wrong to precipitate this. All he did was accidentally post something into the fertile ground of that age-old debate: "US standards vs everyone else" (technically North America, but the US made it that way). Most everyone runs 240v 50Hz (or some variation thereof, assuming your country can make up its mind).
We've only ever needed to know the country when dealing with specific things to unusual stuff like electricity (i.e. if you have blue wires, you're probably in the UK), and a great many questions do indeed involve the US. But we also shouldn't assume everything is the US either. Do we need to mandate a location now to avoid future fights like this?
