Re: Generator doesn't work with Direct Vent Hot Water Heater
That 10awg wire that is 6 inches deep in the earth probably doesn't qualify as a proper ground (it would have to be a very long wire to provide sufficient contact surface and the soil conditions would have to be just right to get away with such a shallow depth). Other then dissipating static electricity (which is also important) this wire is not useful.
Even if you had a wire from the generator ground bolt to the grounding rod of your home (which is the best way to ground the generator) your water heater would still complain unless there is a bond between the neutral from your generator to ground (meaning the equipment grounding conductor for your home and not the 10 awg wire attached to your generator).
This bond can be inside the generator (some come this way from the factory) and if you are directly plugging in appliances to the generator (using extension cords) that is where it needs to be.
If you are using a transfer switch (or generator lockout kit) the neutral ground bonding is inside your main electric panel (in that case the neutral should not be also bonded to ground inside the generator).
