​Applicable codes and standards

When the stated version of the following standards is superseded by an approved revision, then that revision shall apply.

The DER interconnection shall conform to this guideline and to the applicable sections of the following codes and standards. Specific types of interconnection schemes, DER technologies and EDTI's distribution systems may have additional requirements, standards, recommended practices or guideline documents external to this guideline. The applicability and hierarchy of those, with respect to the requirements herein, are beyond the scope of this guideline. This list of standards is therefore not to be regarded as all-inclusive.
