(A) Supply Side. A fuel cell system power source shall be <br />permitted to be connected to the supply side of the service <br />disconnecting means as permitted in 230.8(5). <br /> <br />(B) Load Side. A fuel cell system power source shall be <br />permitted to be connected to the load side of the service <br />disconnecting means of the other source(s) at any distribu- <br />tion equipment on the premises, provided that all of the <br />following conditions are met: <br /> <br />(1) Each source interconnection shall be made at a dedi- <br />cated circuit breaker or fusible disconnecting means. <br />(2) The sum of the ampere ratings of over current devices <br />in circuits supplying power to a busbar or conductor shall <br />not exceed the rating of the busbar or conductor. <br />Exception: For a dwelling unit, the sum of the ampere <br />ratings of the over current devices shall not exceed 120 <br />percent of the rating of the busbar or conductor. <br />(3) The interconnection point shall be on the line side of <br />all ground-fault protection equipment. <br />(4) Equipment containing over current devices in circuits <br />supplying power to a busbar or conductor shall be marked <br />to indicate the presence of all sources. <br />(5) Equipment such as circuit breakers, if back fed, shall <br />be identified for such operation. <br />(6) The circuit breaker on the dedicated output of a utility <br />interactive inverter shall be positioned in the distribution <br />equipment at the opposite (load) end from the input <br />feeder connection or main circuit location. A permanent <br />warning label shall be applied to the distribution <br />equipment with the following, or equivalent: <br /> <br /> WARNING <br /> FUEL CELL POWER SYSTEM OUTPUT. <br />DO NOT RELOCATE THIS CIRCUIT BREAKER. <br /> <br />VIII. Outputs Over 600 Volts <br /> <br />692.80 General. <br /> <br />Fuel cell systems with a maximum output voltage over 600 <br />volts ac shall comply with the requirements of other articles <br />applicable to such installations. <br /> <br />Section 20.20.030 Article 90-4 - Enforcement: <br /> <br />94 <br /> <br /> <br />
