Answer: 

Yes.. it can work but first you should not forget to 'turn-off' the main circuit breaker and 'turn-off' and un-plug' first your generator before you switch back to Distribution Utility (DU) normal power.

Plugging a portable generator into a house outlet, known as back feeding, can be dangerous.

It could potentially send electricity back into the grid, endangering utility workers and your neighbors.

If you need to use a generator, it’s best to follow proper protocols and consult an electrician for a safe setup, such as using a transfer switch to isolate your home from the grid while running the generator.
