(b) All apparatus and electrical wiring
				  connected or to be connected to the cooperative/utility's distribution system
				  point of delivery shall be at the producer's expense, and shall be installed
				  and maintained in accordance with the NEC, as adopted by the Commission in OAC

				  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

				  recognized testing laboratory as being compliant with UL 1741,
				  2nd 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

				  Director certifying that as of the date of the Certification Letter, the
				  utility's interconnection agreements meet the requirements in (b), (c) and (d)
				  of this Section, or if the interconnection agreements do not meet the
				  requirements in (b), (c) and (d) the reason therefor.
