In the event of a conflict between the NEC and an applicable municipal code, the latter shall govern. The cooperative/utility reserves the right to refuse to connect at the point of delivery to any wiring or apparatus which does not meet the requirements in (b) of this Section, and the cooperative/utility may, without advance notice, discontinue purchase from any producer when a defective condition of wiring or equipment upon the premises of the producer is discovered. In the event a producer desires to change the size of his electrical equipment and maintain his status, he shall notify the cooperative/utility in writing sufficiently in advance so that its meter and other equipment may be enlarged to properly handle the increased load or generation.

(c) Power inverter based apparatus utilized in the system to be connected to the cooperative/utility's distribution system point of delivery shall be Underwriters Laboratory ("UL") 1741 listed or certified by a nationally recognized testing laboratory as being compliant with UL 1741, 2^nd Revision standards before the system is connected to the cooperative/utility's distribution system point of delivery. Proof of this certification must be provided at the producer's expense. The cooperative/utility reserves the right to refuse to connect at the point of delivery to any apparatus which does not meet the requirements in (c) of this Section, and the cooperative/utility may, without advance notice, discontinue connection with any producer when a defective condition of equipment upon the premises of the producer is discovered.

(d) All relevant apparatus utilized in the system to be connected with the cooperative/utility's distribution system point of delivery shall be certified by a nationally recognized testing laboratory as compliant with the Institute of Electrical and Electronics Engineers (IEEE) 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems before the system is connected to the cooperative/utility's distribution system point of delivery. Proof of this certification must be provided at the producer's expense. The cooperative/utility reserves the right to refuse to connect at the point of delivery to any apparatus which does not meet the requirements in (d) of this Section, and the cooperative/utility may, without advance notice, discontinue connection with any producer when a defective condition of equipment upon the premises of the producer is discovered.
