I just got a second wen inverter generator 2250watts, both are still in the box, its one of those enclosed type, wen website has them for 385 right now. anyway, i saw on the front it has a knob or something for ground wire, does it need to have a ground wire to run my chest freezer? thanks....

No. Grounding to an electrode such as a ground rod provides no low-resistant path for a ground-fault to operate an overcurrent device.

Proper grounding is accomplished through the same wiring method used to power the freezer.

Not sure what that means, Back Pack Hack????? If the freezer is disconnected from the home's power outlet, how is anything grounded?

If you don't want to be shocked when you touch the frig, best to add a ground to the case of the generator. When the generator is connecter to only the frig even with a 3 wire cord there is no connection to earth ground.

Earth grounding does zip for shock protection. The earth has such a high resistance it WILL NOT cause a breaker/fuse to open in case of a fault.

In fact, here's what 250.4(A)(5) of the National Electrical Code says:

(5) Effective Ground-Fault Current Path. Electrical equipment and wiring and other electrically conductive material likely to become energized shall be installed in a manner that creates a low-impedance circuit facilitating the operation of the overcurrent device or ground detector for high-impedance grounded systems. It shall be capable of safely carrying the maximum ground-fault current likely to be imposed on it from any point on the wiring system where a ground fault may occur to the electrical supply source. The earth shall not be considered as an effective ground-fault current path .
Pay close attention to the last sentence.

You can never go wrong by grounding electrical units to a dedicated ground rod (preferably copper coated and 6' deep) but don't really think it's necessary in your case. But if there's a special hook up on the unit for a ground then why not?

Those are for those cases when you use the genny to energize a building's existing wiring system. Again, if you're using cords, then grounding to earth is a waste of time and money.
