Yep it sure is. So how about this .. do not use a ground rod on a portable generator ... .. unless your paranoid about lightning

Just thought somebody might like to know why ..

Exactly my understanding:
If your generator has a floating ground then you do not need to ground when connecting to the home system, but you should ground if operating stand-alone. (my brief summary)

The typical consumer or household generator is center tapped and then it gives you 120 volts as well as 240. It may or may not be "grounded" by having (or not having) the neutral bonded to the generator frame perhaps using a removable green headed screw.

Bonding of the generator neutral to ground will also happen when the generator is used to power a home electrical system via the main panel.

I put a meter to the generator frame and Nema plug ground plate. Reads continuity.

As a side note, when the power company installed the transfer switch (awhile ago), we did a power On check with the generator connected and running. Power to the CB panel was correct.

I'll hold off on the ground rod.
