I have been asked to provide a grounding detail for (2) services. See attached PDF. I appreciate any comment!

Thanks
Dan Craven

The GEC's to the water pipe are too small. Since you have a CEE ground rods are not required. Also the #3 aluminum on the secondary of the transformer are too small for a 100 amp OCPD.
