Quick question I can't find an answer for. I am looking to turn a kettle into an ekettle. Because of my design I have no good way of grounding the kettle without soldering or drilling the pot (which I REALLY don't want to do). I however can ground the element very easy. Since the element is the source of the electricity and not the kettle would grounding the element alone be fine, or do I really need to ground the kettle as well?
