I was recently gifted a Champion brand, 3550 watt, 120 v generator. I had intended on hooking it up to my electrical panel via generator plug inlet box and interlock kit, but after doing some research I've come to realize I've got a complex problem.
In theory, I could rig something up to jumper the single hot into two separate hots and power both legs of my panel. But, I have several MWBCs in my house, and my understanding is that would create a situation where I am overloading the shared neutral because the generator is only producing a single phase of 120v power. Is this correct?
What are my options, other than trying to exchange or sell for a 240 v generator?
