I'm curious since you guys still use 240V for washer, dryer, cooker, EV charger, etc. Could you legally install a 240V socket (with a different plug type) and use an appliance from a 240V country?
I get it would probably be overkill for a kettle alone but I'm curious why it's only common for some things. Is it regulated, like do devices need a special approval to be allowed to run 240V in US?
You're right about the frequency for sure, most things with an AC motor for example wouldn't handle it.
But a quick search shows people have done this for things like kettles without issue.
