38.5.8405    CERTIFIED EQUIPMENT

(1) An interconnection request may be eligible for expedited interconnection review as determined under ARM 38.5.8404 if the small generator facility uses certified interconnection equipment. Interconnection equipment shall be deemed certified upon establishment of all of the following:

(a) The interconnection equipment has been labeled and is publicly listed by a NRTL at the time of the interconnection application;

(b) The NRTL testing the interconnection equipment makes readily available for verification all test standards and procedures it utilized in performing such equipment certification, and, with consumer approval, the test data itself. The NRTL may make such information available on its web site and by encouraging such information to be included in the manufacturer's literature accompanying the equipment;

(c) The applicant verifies that the intended use of the interconnection equipment falls within the use or uses for which the interconnection equipment was labeled, and listed by the NRTL.

(2) If the interconnection equipment is an integrated equipment package such as an inverter, then the applicant must show that the generator or other electric source being utilized is compatible with the interconnection equipment and is consistent with the testing and listing specified for this type of interconnection equipment.

(3) If the interconnection equipment includes only interface components (switchgear, multifunction relays, or other interface devices), then the applicant must show that the generator or other electric source being utilized is compatible with the interconnection equipment and is consistent with the testing and listing specified for this type of interconnection equipment.

(4) Interconnection equipment must be evaluated by a NRTL in accordance with the following codes and standards:

(a) IEEE 1547-2003 Standard for Interconnecting Distributed Resources with Electric Power Systems (including use of IEEE 1547.1-2005 testing protocols to establish conformity); and

(b) UL 1741 Inverters, Converters, and Controllers for Use in Independent Power Systems. 

(5) Certified interconnection equipment shall not require further design testing or production testing, as specified by IEEE Standard 1547-2003 Sections 5.1 and 5.2, or additional interconnection equipment modification to meet the requirements for expedited review; however, nothing herein shall preclude the need for an interconnection installation evaluation, commissioning tests or periodic testing as specified by IEEE Standard 1547-2003 Sections 5.3, 5.4, and 5.5, or for a witness test that may be conducted by the EDC.
