an argument about a ground rod for a guardian generator(13k) with an auto x-fer switch has arisen between two sparkys(what electricians arguing the code hmmmm).
Anyway, I am in the mindset that a standby generator is exactly that and not a seperately derived system.
Plus if memory serves(been awhile since I installed one)the ground and neutral are bonded together at the source by the factory and the transfer switch is fed with 4 conductors bonding it to the service panel.
So driving a seperate ground rod isn't required. Even though there is a ground lug on the frame for equipment grounding the generator is bonded via the factory whip to the x-fer switch(green conductor)which can easily be checked with a meter.
What say you?
Thanks as always,
