My wife moved here from the UK... she brought with her a unit called a "hostess trolley" it is used to keep food warm before serving. She loves it but it's a 220/240 volt unit.
We've tried running it with a converter and that didn't work.
We've re-wired it for a 220 volt US plug and that didn't work.
So, it must be a problem with 60 / 50 hertz.
Anybody have an idea about what else we could try to make it work in the States?
