Residential power in the US is universally (to the best of my knowledge) three pole single phase 60 Hz 240V. The (common) wall outlets are certainly 120V, but large appliances are 240V. (A typical electric dryer is ~5kW at just over 20A.) As long as I'm ackchyuallying, I'll also point out that radiant cooktops don't have LEDs in them (at least I've never come across one like that). The red light (which I assume you're referring to) is just what happens when the element in an infrared heater (space heater, toaster, etc) gets hot.
