^ This is the way to go, if you can't install a mechanical lockout on your HOUSE panel. I know you fix aircraft, and are used to strictly following procedures....but an interlock will take any room for error away. It sounds like you may not be able to use one in your situation. I've worked for the power company for 44 years, and seen more than one instance where someone got all excited about the power being back on, and goofed up their disconnect of the generator before flipping the main back on. A guy that lives on Michigan Street in Tulsa, OK did that....and you wouldn't believe the fireball that came out of his garage. Flash burnt his eyes when his breaker box exploded, and started a brush fire behind his and his neighbors house when the fault current he created burnt down the open wire secondary we had just put up to get the power back on. That was after the power had been out for a week because of the ice storm that hit right before Christmas of 2007. Please just be careful. I don't want you to get hurt.
