circuits. In all installations, the rating of the over current <br />device connected to the output of the inverter shall be less <br />than the rating of the neutral bus in the service equipment. <br />This equipment shall be marked with the following words <br />or equivalent: <br /> <br /> WARNING <br />SINGLE 120-VOLT SUPPLY, DO NOT CONNECT MULTIWIRE <br />BRANCH CIRCUITS! <br /> <br />III. Disconnecting Means <br /> <br />690.13 All Conductors. <br /> <br />Means shall be provided to disconnect all current-carrying <br />conductors of a photovoltaic power source from all other <br />conductors in a building or other structure. Where a circuit <br />grounding connection is not designed to be automatically <br />interrupted as part of the ground-fault protection system <br />required by 690.5, a switch or circuit breaker used as a <br />disconnecting means shall not have a pole in the grounded <br />conductor. <br /> <br />FPN: The grounded conductor may have a bolted or terminal <br />disconnecting means to allow maintenance or <br />troubleshooting by qualified personnel. <br /> <br />690.14 Additional Provisions. <br /> <br />Photovoltaic disconnecting means shall comply with <br />690.14(A) through (C). <br /> <br />(A)Disconnecting Means. The disconnecting means shall <br />not be required to be suitable as service equipment and <br />shall be rated in accordance with 690.17. <br /> <br />(B) Equipment. Equipment such as photovoltaic source <br />circuit isolating switches, over current devices, and <br />blocking diodes shall be permitted on the photovoltaic side <br />of the photovoltaic disconnecting means. <br /> <br />(C) Requirements for Disconnecting Means. Means shall be <br />provided to disconnect all conductors in a building or other <br />structure from the photovoltaic system conductors. <br /> <br />73 <br /> <br /> <br />
