The electrical portion of solar PV systems shall be installed in accordance with the California Electrical Code. 1204.2 Access and Pathways Chapter 12 Energy Systemshttps://up.codes/viewer_export/juris_key/california/pub/california_fire_code_2019/ref/12 6/24Roof access, pathways, and spacing requirements shall be provided in accordance with Sections 1204.2.1 through 1204.3.3. Pathways shall be over areas capable of supporting fire fighter accessing the roof. Pathways shall be located in areas with minimal obstructions, such as vent pipes, conduit or mechanical equipment.Exceptions:1. Detached, no habitable group structures including, but not limited to, detached garages serving group R-3 buildings, parking shade structures, carports, solar trellises and similar structures.2. Roof access, pathways and spacing requirements need not be provided where the fire code official has determined that rooftop operations will not be employed. 1204.2.1 Solar Photovoltaic Systems for Group R-3 Buildings Solar photovoltaic systems for Group R-3 buildings shall comply with Sections 1204.2.1.1 through 1204.2.1.3.Exceptions :1.These requirements shall not apply to structures designed and constructed in accordance with the California Residential Code.2. These requirements shall not apply to roofs with slopes of 2 units vertical in 12 units horizontal or less. 1204.2.1.1 Pathways to ridge not fewer than two 36-inch-wide (914 mm) pathways on separate roof planes, from lowest roof edge to ridge, shall be provided on all buildings. Not fewer than one pathway shall be provided on the street or driveway side of the roof. For each roof plane with a photovoltaic array, not fewer than one 36-inch-wide (914 mm) pathway from lowest roof edge to ridge shall be provided on the same roof plane as the photovoltaic array, on an adjacent roof plane or straddling the same and adjacent roof planes 1204.2.1.2 Setbacks at ridge for photovoltaic arrays occupying 33 percent or less of the plan view total roof area, a setback of not less than 18 inches (457 mm) wide is required on both sides of a horizontal ridge. For photovoltaic arrays occupying more than 33 percent of the plan view total roof area, a setback of not less than 36 inches (457 mm) wide is required on both sides of a horizontal ridge. 1204.2.1.3 Alternative setbacks at ridge where an automatic sprinkler system is installed within the dwelling in accordance with Section 903313 setbacks at the ridge shall conform within the dwelling in accordance with Section 903.3.1.3, setbacks at the ridge shall conform to one of the following:1For photovoltaic arrays occupying 66 percent or less of the plan view one of the following:1. For photovoltaic arrays occupying 66 percent or less of the plan view total roof area a setback of not less than 18inches (457 mm) wide is required on both sides total roof area, a setback of not less than 18inches (457 mm) wide is required on both sides of a horizontal ridge 2 For photovoltaic arrays occupying more than 66 percent of the plan view a horizontal ridge.3. For photovoltaic arrays occupying more than 66 percent of the plan view total roof area a setback of not less than 36inches (914 mm) wide is required on both sides total roof area, a setback of not less than 36inches (914 mm) wide is required on both sides of a horizontal ridge a horizontal ridge. 120.4.2.2 Emergen1204.2.2 Emergency escape and rescue openings panels and modules installed on Group R-3 buildings shall not be placed on the portion of a roof that is below an emergency escape buildings shall not be placed on the portion of a roof that is below an emergency escape and rescue opening A pathway of not less than 36 inches (914 mm) wide shall be provided and rescue opening. A pathway of not less than 36 inches (914 mm) wide shall be provided to the emergency escape and rescue opening the emergency escape and rescue opening.120.4.2.3 Locations of DC Conductors Conduit 1204.2.3 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 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 ventilate 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 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 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 the array to the DC combiner box. The DC combiner boxes shall be located such that conduit runs are minimized in the pathways between arrays DC wiring shall be installed in metallic runs are minimized in the pathways between arrays. DC wiring shall be installed in metallic conduit or raceways when located within enclosed spaces in a building Conduit shall run a conduit or raceways when located within enclosed spaces in a building. Conduit shall run along the bottom of load bearing members the bottom of load bearing members. 1626 E Trinidad Way01/25/23
