Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.

You can use a 2 pole 30A breaker and use #10 wiring for a 5500 watt genset.

Please be sure to install a main breaker interlock so that your generator does not backfeed into the grid.

Please let me now if you need further clarification.
