The question appeared because some people wrote that by pushing the GEN 1 LINE push button it would isolate all the components from the AC1 BUS BAR. And that is not correct, because the GEN2 will then supply the AC1 BUS.
So from what I understood the GEN 1 Line p/b is only a way to have fuel pumps connected to the IDG 1 after completing the SMOKE ELEC CONFIG.
If we would not carry on the SMOKE drill would not make much sense having that p/b at all.
correct?
