I agree in what you're saying but my question relies on what is the meaning of disconnecting the GEN1 from the AC1 (in smoke config)?? I could understand that in case of smoke config we should isolate the main components by disconnecting the AC1 BUS BAR (to reduce the chance of fire) but when you do it so by pressing the GEN 1 Line p/b you will continue to have the AC1 BUS BAR because the GEN 2 will then supply it as it is describes in the FCOM 3.02.26 p6a, so I do not see much difference besides the fuel pumps being supplied directly from the IDG!!
Thanks for your help.
