I will be installing a standby generator located about 50 ft. from the
grounding rod for my house. If I ground the generator only in main
panel,
then there is a possibility that the generator frame will be at a
slightly
different potential than the adjacent earth on which someone touching
the
generator may be standing. If I install a ground rod at the generator
location, then I will be introducing a ground loop with its associated
problems.

How, according to the NEC, should the generator be grounded? Please
provide a code reference (or quote) if you can.

Many thanks for any help.

There should be grounding requirements in the installation instructions.
Generally there is an external ground lug on the frame or housing of the
generator. This would get connected to your grounding electrode conductor
for lightning protection. There should also be an equipment grounding
conductor that is run with generator conductors to the transfer switch or
panel that you will be supplying the generator power to.

The gen only needs small wire attached to even a long nail driven into
the ground, a lightning rod is overkill



LOL. You guys are making me laugh tonight. Thanks. This reminds of the
person a few years back who posted about sticking a wire from her computer
out the window to a coat hanger in the ground because her house was not a
grounded system.

Maybe on the next job I'll connect a ground wire good for 7000 amps to a
long nail and show the inspector this thread. LOL
