TCF - nice concise description, I did 1-11 electrics in 1973 with a guy called Colin Webster in CWL, by the end of the course we had to draw the bus bar layout or fail ! I've been sat here for a couple of days trying to remember what the SSB was called ! thank you.
Chris - On the 707 and 727 the generators were connected in parallel onto the "Tie Bus" the F/E had to manually parallel the generators before connecting them to the tie bus, remember the pulsing neon lights ? The AC bus bars were then fed from sections of the tie bus and could be isolated by judicious use of the "bus tie breakers" under fault conditions normally perated in parallel however.
Never really had much to do with 747 classics but seem to recall they were similar except that the paralleling was automatic.
