Cover Page Notes: All Jobs [All work shall be in compliance with the most current Los Angeles County fire code and its sections] Battery [When ESS is installed inside garage, - Any planned or existing attached garage shall comply with all applicable codes and standards, and with the manufacturer's installation manual(s) to which the equipment has been listed, including requirements pertaining to fire protective features (E.g., gypsum board, doors, and ducts), and to alarm/detector devices // EXTERIOR ESS UNITS WILL NOT BE INSTALLED WITHIN 5' (IN ANY DIRECTION) OF ALL WINDOWS, DOORS, AND HVAC INLETS. ESS UNITS WILL BE INSTALLED NO LESS THAN 3' FROM OTHER ESS UNITS.]

Site: ## **All Jobs** All buildings on property are to be properly labeled and called out as habitable or non-habitable. For systems with multiple strings, the plans shall clearly identify how all modules are mapped to each string and/or inverter output.

Site Notes: All Jobs [ALL ELECTRICAL EQUIPMENT SHALL BE LABELED, LISTED, OR CERTIFIED BY A NATIONALLY RECOGNIZED TESTING LABORATORY ACCREDITED BY THE UNITED STATES OCCUPATIONAL SAFETY HEALTH ADMINISTRATION. // Project is NOT located in a fire hazard severity zone, nor in a state-responsibility area and is therefore exempt from the requirement per CRC R377.6.2 and CBC 706a.2 for securing mesh at the level of the underlayment or decking/sheathing, directly overt the vent opening through the decking/sheathing that is located at the ridge // 36 in wide emergency escape and rescue pathways will be provided to the center of the operable portions of all operable doors and windows located above the roof plane when a said door or window is both setback from the eave and serving a habitable space. Windows serving vaulted ceiling only shall be exempt. No electrical components associated with the battery integrated PV system shall be located above the roof decking for the full extent of these pathways. Compliance shall be subject to inspection by the fire code official as demonstrated by the lifting of tiles by responsible party as necessary for confirmation. (CFC 1204.2.2)] MPU [NEW SERVICE PANEL TO REPLACE EXISTING AT SAME LOCATION (Pending Utility company)]

Roof Plan

For systems with multiple strings/inverters, the plans shall clearly identify how all modules are mapped to each string and/or inverter input

Attachment Detail

Distance from top of module to roof is to be called out

Electrical Diagram: FOR ALL PROJECTS If the point of interconnection uses Section 705.12(b)(2)(3)(c), provide this note on the single line diagram: “These are the only circuit breakers in this panel at this time.” Do not use 90°C ampacities/derate factors. FOR MPU PROJECTS (2 ground rods at least 6' apart is 1 supplemental electrode) If ground rods, comply with the following: 250.53(A)(2) & (3) Resistance of Electrodes: For the ground rod specified on the single line diagram, indicate that there shall be two ground rods separated by six or more feet Identify if the main panel is fed via an overhead drop or underground feed. If overhead, provide the size of the service entrance conductors AND ground size (GEC) Identify GEC size to Table 250.66 If solar ready MPU: Show model number for solar ready service panels FOR HOT BUS PROJECTS If MSP is a hot bus and has 6 or less breakers, provide a panel schedule identifying all the breakers FOR GMA PROJECTS The wire from the inverter to the AC disconnect must also be sized to #6 Per SCE requirements, specify the distance from the GMA to the fused disconnect as 2-3' maximum Indicate that equipment grounding electrode conductor (EGC) shall be in separate conduit. The EGC is not installed in the liquid-tight flexible conduit from the AC disconnect to the GMA GMA requires GEC to be ran in its own conduit to MSP FOR Battery PROJECTS There shall be a shut off switch that is not located on the battery itself.

Electrical Diagram Notes: All Jobs [THE PV BREAKER SHALL BE LOCATED AT THE OPPOSITE END OF THE MAIN BREAKER OR INPUT FEEDER // ALL TERMINALS TO BE RATED AT 75°C MINIMUM // All electrical work shall be designed per 2020 Los Angeles County electrical code, 2019 California Electrical Code, and 2017 National Electrical Code. // 110.2 Approval: All electrical equipment shall be labeled, listed, or certified by a Nationally Recognized Testing Laboratory accredited by the United States Occupational Safety Health Administration.] MPU [GEC SIZE FROM MAIN SERVICE PANEL TO GROUND ROD TO BE #4 AWG.
