How to choose a heater for lunch box heating?
Good afternoon! I want to make a heated lunch box for food. Design based on a medical sterilizer.
According to the principle of work, I would like to heat food like in a water bath. That is, inside a larger container, water, boiling will heat a smaller container with food. Since both containers are metal, it is necessary to take care of electrical safety.
What ten could you recommend for such a design so that water, wet, dry, boils as soon as possible? (Ideally - as in the el. Kettle). I think it should be mounted inside a larger container, and not underneath it (as in the original device).
Is it possible to apply a principle here similar to deep fryers, but with sufficient power of a heating element (up to 2 kW), again in order to heat food from boiling water as quickly as possible? How to make grounding and is it necessary?

Good afternoon. TEN is of course dry, they are by definition safer. Grounding is generally mandatory since 2003 (or since 1997, different sources have different requirements). What does it mean how to do it right? Connect the housing to the protective conductor, connect it to the PE bus in the electrical panel, and connect the latter to the grounding circuit.
