Most important thing: Portable generators are made in two different ways: An
isolated neutral and a bonded neutral. If your not using a transfer switch you
need to have the neutral bonded to the following things: ground (that means a
grounding electrode, and a grounding electrode conductor), the frame of the
generator, and the equipment grounding conductor.
Without those connections the safety of your setup will be severely
compromised.
(Most portable generators have that all wired internally, except for the
grounding electrode which, if the use of the generator is temporary, I think
your allowed to skip it.)
Again, GLHF!
