Question for aviation experts.
I noticed that the power sockets in an airplane cabin for plugging in your laptop have a hole for earthing pin. Is this actually connected to the frame of the airplane?
If this is the case I presume the aircraft mains voltage is distributed in a TN configuration including RCD instead of IT?
