  • Q210293

    Is anyone able to confirm whether 210283 has been answered correctly? Question asks what is the normal power source for windscreen heating, and gives 3ph AC as the answer. My understanding of windscreen heating is that it is usually provided by single phase AC controlled by DC. The explanation provided refers to electric heating mats, so I wonder if the question has been misread when the answer selected and explanation written.

    Many thanks,
