More critical than power is length. As a rule of thumb, over distances less than 1/10th the wavelength, metal strips, ordinary wire, or anything you might use to conduct electricity is probably fine. Longer than 1/10th the wavelength, and the "wires" start to look more like "antennas", leading to unintentional reception or radiation. In these cases it's ...

There is no such thing as a minimum power level at which a conductor will start radiating. If it radiates at all, then the radiation will be proportional to the power applied. Therefore, the maximum usable power in this circumstance is the power at which such radiation will interfere with (or damage) the receiver, and in order to know it you must test ...
