1.7 L Electric Kettle Wattage
For one 1.7 L, 120 V AC electric kettle, use 1,500 W running watts and 1,500 W starting watts as planning values. The kettle is modeled as a short, full-power load that switches off when the water boils. These are low-confidence typical values, not the confirmed rating of every 1.7 L kettle. No m…
