NOTES:61/1 2/9 1. All exposed photovoltaic system conductors on the roof will be PV wire. 2. All photovoltaic system conductors will be 90 degree C rated in accordance with CEC 690.31B, Table 310.16, Table 310.17. 3. Where DC conductors are run inside the building or attic, they shall be contained in a metal raceway in accordance with CEC 690.31 E. 4. All exterior conduit, fittings and boxes shall be rain-tight and approved for use in wet locations in accordance with CEC 314.15. 5. All conductors exposed to sunlight shall be listed as sunlight resistant in accordance with CEC 300.6 Cl, 310.8 D. 6. All photovoltaic output circuits operating above 30 volts shall be installed in a readily accessible location and in electrical raceways in accordance with CEC 690.31. 7. All metallic raceways and equipment shall be bonded and electrically continuous in accordance with CEC 250.90,250.96. 8. The photovoltaic arrays shall be provided with DC ground-fault protection in accordance with CEC 690.5. 9. The DC grounding electrode conductor shall be sized according to CEC 250.166,690.47B 10. The DC grounding electrode shall be bonded to the AC grounding electrode and the conductor shall be no smaller than the largest grounding electrode conductor, either AC or DC CEC 690.47 C 7. 11. The AC grounding electrode conductor shall be sized according to NEC 250.66, Table 310.15 B 6, CEC 690.47. 12. Grounding bushings are required around pre-punched concentric knock outs on the DC side of the system. CEC 250.97 13. The grounding electrode to be protected from physical damage between the grounding electrode and the panel or inverter if smaller than #6 copper wire in accordance with CEC 250.64B. 14. Grounding electrode conductor will be continuous, except for splices or joints at bus bars within listed equipment in accordance with CEC 250.64 C. 15. If a water pipe is use for the grounding an additional driven rod ufer ground will be installed in accordance with CEC 250.50. 16. City Building Inspector shall inspect accessible structural connections and the house current side of the system, all other equipment shall be UL listed and approved. 17. A smoke detector, approved and listed by the State Fire Marshall, shall be installed in each dwelling when a permit for alterations, repairs or additions exceed $1,000.00. A battery powered smoke detector satisfies the requirements for a smoke detector. (907.2.10.2 CBC) 18. Approved combined smoke alarms and carbon dioxide alarms shall be acceptable. 19. A carbon monoxide detector shall be installed in the specific existing dwelling unit that have attached garages or fuel-burning appliances for which a permit is issued for alterations, repairs or additions exceeding $1,000.00. Listed single-or multi-station carbon monoxide alarms may be used. The alarm shall receive its primary power from the building wiring except it is permitted to be solely battery operated where repairs or alterations do not result in the removal of wall and ceiling finishes or there is no access by means of an attic. (R.315 CRC) 20. Locations of DC conductors. Conduit, wiring systems, and raceways for photovoltaic circuits shall be located as close as possible to the ridge or hip or valley and from the hip or valley as directly as possible to an outside wall to reduce trip hazards and maximize ventilation opportunities. Conduit runs between sub arrays and to DC combiner boxes shall be installed in a manner that minimizes the total amount of conduit on the roof by taking the shortest path from the array to the DC combiner box. The DC combiner boxes shall be located such that conduit runs are minimized in the pathway between arrays. DC wiring shall be installed in metallic conduit or race ways when located within enclosed spaces in a building. Conduit shall run along the bottom of load bearing members. CFC 605.11.2
