(3) Circuits Using inverters. The requirements in <br />690.72(B)(2) shall not apply to ac or dc circuits using <br />inverters to control the battery charging process by <br />feeding power into the utility system. These circuits, <br />used in several modes, shall be sized and protected as <br />required in 690.8. <br /> <br />690.74 Battery Interconnections. <br /> <br />Flexible cables, as identified in Article 400, in sizes 2/0 <br />AWG and larger shall be permitted within the battery <br />enclosure from battery terminals to a nearby junction box <br />where they shall be connected to an approved wiring <br />method. Flexible battery cables shall also be permitted <br />between batteries and cells within the battery enclosure. <br />Such cables shall be listed for hard service use and <br />identified as moisture resistant. <br /> <br />IX. Systems Over 600 Volts <br /> <br />690.80 General. <br /> <br />Solar photovoltaic systems with a maximum system <br />voltage over 600 volts dc shall comply with Article 490 and <br />other requirements applicable to installations rated over 600 <br />volts. <br /> <br />690.85 Definitions. <br /> <br />For the purposes of Part IX of this article, the voltages used <br />to determine cable and equipment ratings are as follows. <br /> <br />Battery Circuits. In battery circuits, the highest voltage <br />experienced under charging or equalizing conditions. <br />Photovoltaic Circuits. In dc photovoltaic source circuits and <br />photovoltaic output circuits, the maximum system voltage. <br /> <br />20.20.028 Article 692 Amended in its entirety - Fuel Cell Systems. <br /> <br />Article 692 of the California Building Standards Code 2001 Edition <br /> (24 C.C.R.), and including by reference the National Electrical <br /> Code, is amended in its entirety to read as follows: <br /> 86 <br /> <br /> <br />
