This is for commercial aircraft 28v and 115vac. However this brings up the point planes like B787 use electronic circuit breakers. The real point of them is remote monitoring and control with reduced wiring and increased data on status of electrical system. With a commercial airliner it is far easier to run one feed line to an area then have local busses controlled by a ECB controller. Airliners did this with traditional CB's in cargo hold, tail, things that did not need to be reset in flight. They are using ECB control centers to control and protect critical devices locally. So small gauge data wires and one large feed replaces discreet wires running from the cockpit to individual CB's.
B787 is a very electric plane. Instead of hydraulic lines running out to control ailerons, spoilers and flaps, they have local electrically powered hydraulic units. So only wires need to be run. Using a ECB control center in that area there are less individual long wire runs. The large feed wire has it's own current protection. Also the data from the controller can tell the computer about the condition of the motor. Very clever.
If you followed all that, advantage ECB's, not as great on small planes as large planes. It is not new or unproven technology. Related is the CANBUS on cars, motorcycles for many years, it has pros and cons. CANBUS can be a nightmare. If you want to connect trailer lights direct to your tail lights, forget it. Need another CANBUS controller. The electrical system is controlled through software basically. If it detects extra load it shuts down. It may be great, may not be great. The great part is I can connect a special diagnostic cable from the cars data port to my laptop, running very specific software for my car (VW), I can read all kind of data, down to actual voltage at a specific device. It knows if there is an open or short or higher resistance. Pretty cool but complicated. Bottom line is you can't screw around with the electrical system freely. Even changing a light bulb to a different kind may cause it to get confused.
