The nest gets its power from your furnace it will only be the voltage put out from your circuit board, usually 5 volts. It does not require power from a receptacle. You need to confirm that your furnace is compatible with your nest first using their online comparability chart.

the nest has an internal battery but it needs a constant 24v low voltage power source usually supplied by the heating/cooling system. I have an older central heat/AC system that did not supply power (used the old round mercury switch) and got a 1st gen Nest to work by feeding it power through a 24 v door bell power transformer (made for a hard wired door bell) purchased at Home Depot. But most systems made in the last 15 or so years will supply the power needed in the wiring loom.

No, it will not work when line voltages (110-240v) switched at the thermostat.

Nest has a wonderful customer service that will be the best with your questions. However, I may be wrong but I don't know any thermostat that requires even 110 volts. So I'm not an expert but would say no. But a call to Nest will answer. Most heater/air cond. have a low voltage and/or a low voltage transformer that run the thermostat, The transformer may be a higher voltage but it is stepped down to run the thermostat,
