Whats up fellas?
Good replies. Yes it is a manufactured home. 200A breaker in the (only) e panel. Ive fed the panel w 3-0
or rather, ive taken the feeders to a nema 3 can 12X12 to the outside of the house where ill set the gen. Ground rods are by the can on outside of manuf. home. Ive ran EGC & GEC from panel to box, GEC hits the can and passes thru to rods unbroken and E.G. is waiting in box for gen. im on a Reservation so i can "get away" with alot, no inspections. But i am code compliant. Seems i'll bond in the panel and ground the gen.

If the noodle is bonded at the gen. I dont want to put a jumper in the panel.. right??

Right.
If you have a transfer rather than the generator being the only source, then if you bond at the genny you have to switch the noodle as well as the hots.
The NEC requires, in that case, a bond on the POCO side of the transfer switch.

At the panel your GES must be connected to the EGC, not the noodle.

Install two rods and bond 'em to noodle and EGC at the gennie.

? Why would he need a GEC / GES at the panel ?

All electrified buildings and structures are required to have a grounding electrode system [250.50].

Then see 250.32 Buildings or Structures Supplied by a Feeder(s) or Branch Circuit(s).

550.16 Grounding.
feeder wiring to" the service ground" in the service-entrance equipment "located adjacent to the mobile home location".

Those grounding requirements are for a service-supplied mobile home or manufactured home. There is no service.

As such, grounding requirements fall back to Article 250. 550.32(B)(5) even hints to this where it says "The instructions shall clearly state that other methods of grounding are found in Article 250."

IMO the above quoted simply says the manufacture in their instructions for example below will specify one method i.e. ground rods but other methods i.e. a plate electrode are found in article 250.

" Use a listed 5/8 inch diameter by eight foot long iron electrode or nonferrous
rod of at least 1/2 inch diameter by eight feet long for grounding (larger sizes
may be required by the LAHJ due to soil impedance).

Drive the electrode to a depth of not less than eight feet so that at least eight
feet of the electrode is in contact with the soil.

When rock is encountered, the electrode may be driven at an angle not to exceed
45 degrees from vertical or buried in a trench that is at least 2-1/2 feet deep."

IMO the requirements specify feeder supplied manufactured homes as well as service supplied manufactured homes. The manufacture IMO doesn't care if the supply is a generator or a utility

All that said, If I were to connect a grounding electrode conductor from the manufactures homes distrubution panels equipment grounding bar to two ground rods I would bond that conductor to the same two ground rods I have already driven. I would not drive two additional ground rods for the manufactured home

You are most certainly entitled to your opinion. Mine is that the feeder supplied version is still service supplied as no GES is mentioned for such.

That's a viable and compliant option... just no connecting to the grounded conductor twice. Better if the gennie is close by. Put the gennie at a substantial distance from home and I'd recommend a separate GES simply to save wire cost.
