I'm just saying that the FAA may have overlooked Japan's weird power grid when approving the power circuits.
After a bit of reading the 787 uses a unique approach to power on the plane. Interesting reading if you care to look.
Many commercial aircraft use 24VDC systems, as opposed to the standard 12V automotive systems. Not sure about the '87....the link explains the VAC APU systems. Alternating current makes my head spin!
