True - it makes sense for the UPS to switch to static bypass mode to protect the main circuit.

I'm going with B) False. Who wants their UPS to switch to battery power just because the mains voltage is a little high? That's just asking for trouble.

B) False, that doesn't sound right. The UPS should switch to bypass mode when the mains is within spec, not the other way around.

True, that's the whole point of an UPS - to switch to battery power when the mains voltage is out of range.
