CONSTRUCTION NOTE:

THE PV MODULES ARE CONSIDERED NON-COMBUSTIBLE AND THIS

SYSTEM IS A UTILITY GRID INTERACTIVE SYSTEM

A GROUNDING ELECTRODE SYSTEM IN ACCORDANCE WITH NEC

690-47 AND 250-50 THROUGH 60 250-166 SHALL BE PROVIDED PER

NEC, GROUNDING ELECTRODE SYSTEM OF EXISTING BUILDING MAY

BE USED AND BONDED TO AT THE SERVICE ENTRANCE. IF

EXISTING SYSTEM IS INACCESSIBLE, OR INADEQUATE, OR IS ONLY

METALLIC WATER PIPING, A SUPPLEMENTAL GROUNDING

ELECTRODE WILL BE USED AT THE INVERTER LOCATION

CONSISTING OF A UL LISTED 8 FT GROUND ROD WITH ACORN

CLAMP. GROUNDING ELECTRODE CONDUCTORS SHALL BE NO

LESS THAN #8 AWG AND NO GREATER THAN #8 AWG COPPER AND

BONDED TO THE EXISTING GROUNDING ELECTRODE TO PROVIDE

OR A COMPLETE GROUND.

EACH MODULE WILL BE GROUNDED USING THE SUPPLIED

GROUNDING POINTS IDENTIFIED BY THE MANUFACTURER.

EXPOSED NON-CURRENT CARRYING METAL PARTS OF MODULE

FRAMES, EQUIPMENT, AND CONDUCTOR ENCLOSURES SHALL BE

GROUNDED REGARDLESS OF VOLTAGE.

PROPER ACCESS AND WORKING CLEARANCE AROUND EXISTING

AND PROPOSED ELECTRICAL EQUIPMENT WILL BE PROVIDED

ALL SIGNAGE WILL BE INSTALLED AS REQUIRED BY AND 2020 NEC.

HEIGHT OF INTEGRATED AC/DC DISCONNECT SHALL NOT EXCEED 6'

7".

THE GROUNDING ELECTRODE CONDUCTOR SHALL BE PROTECTED

FROM PHYSICAL DAMAGE BETWEEN THE GROUNDING ELECTRODE

AND THE PANEL (OR INVERTER) IF SMALLER THAN #6 AWG COPPER

WIRE. THE GROUNDING ELECTRODE CONDUCTOR WILL BE

CONTINUOUS, EXCEPT FOR SPLICES OR JOINTS AT BUSBARS

WITHIN LISTED EQUIPMENT.

THE PV CONNECTION IN THE PANEL BOARD SHALL BE POSITIONED

AT THE OPPOSITE (LOAD) END FROM THE INPUT FEEDER LOCATION

OR MAIN CIRCUIT LOCATION.

SITE CONDITIONS SHALL PREVAIL IF NO SCALE IS GIVEN.

DRAWINGS ARE NOT NECESSARILY TO SCALE. ALL DIMENSIONS

SHALL BE VERIFIED BY SUBCONTRACTOR UPON COMMENCEMENT

OF CONSTRUCTION.
