GENERAL NOTES
1.All electrical materials shall be new and listed by recognized
electrical testing laboratory
Custom made equipment shall have complete test data submitted
by the manufacturer attesting to its safety
2.Outdoor equipment shall be NEMA 3R rated or equivalent
3.All metallic equipment shall be grounded
4.Contractor shall obtain electrical permits prior to installation and
shall coordinate all inspections, testing commissioning and
acceptance with the client,
utility co. and city inspectors as needed.
5.The electrical contractor shall verify the exact locations of service
points and service sizes with the serving utility company and
comply with all utility companies requirements.
6.Drawings are diagrammatic only, routing of raceways shall be
option of the contractor unless otherwise noted and shall be
coordinated with other trades.
7.If the roof material or the roof structure not adequate for PV
installation, call the engineer of record print to installation. The
contractor is responsible to verify that the roof is capable of
withstanding the extra weight.
8.If the distances for cable runs are different than shown, the
contractor shall notify the electrical engineer to validate the wire
size. Final drawings will be red-lined and updated as appropriate.
9.Whenever a discrepancy in quality of equipment arises on the
drawing or specifications, the contractor shall be responsible for
providing and installing all materials and services required by the
strictest conditions noted on the drawings or in the specifications
to ensure complete compliance and longevity of the operable
system required by the engineer of record.
PHOTOVOLTAIC NOTES:
1.Rooftop mounted photovoltaic panels and modules shall be tested,
listed and identified by recognized testing laboratory
2.Solar system shall not cover any plumbing or mechanical vents
3.Modules and support structures shall be grounded
unless racking has integrated ground.
4.Removal of an interactive inverter or other equipment shall not
disconnect the bonding connection between the grounding
electrode conductor and the photovoltaic source and/or output
circuit grounded conductors.
5.All PV modules and associated equipment and wiring shall be
protected from physical damage.
6.Live parts of PV source circuits and PV output circuits over 150v to
ground shall not be accessible to other than qualified persons
while energized.
7.Inverter is equipped with integrated DC disconnect, thus providing
ground fault protection
8.All conductors shall be copper and 75 deg rated
9.A single conductor shall be permitted to be used to perform the
multiple functions of dc grounding, AC grounding and bonding
between AC and DC systems.
10.Non-current carrying metal parts of equipment shall be effectively
bonded together. Bond both ends of raceways.

MARKINGS, LABELS AND WIRING SIGNS
A. Purpose: Provide emergency responders with appropriate warning and guidance with respect to isolating solar electric system.
This can facilitate identifying energized electrical lines that connect solar panels to the inverter, as these should not be cut when venting for smoke removal
B. Main Service Disconnect.
1. Residential buildings - The marking main be placed within the main service disconnect. The marking shall be placed
outside cover if the main service disconnect is operable with the service panel closed.
2. Commercial buildings - Tha marking shall be placed adjacent to the main service disconnect clearly visible from the location where the level is operated
3. Markings: Verbiage, Format and Type of Material.
a. Verbiage: CAUTION: SOLAR ELECTRIC SYSTEM CONNECTED
b. Format: White lettering on a red background. Minimum 3/8 inches letter height. All letters shall be capitalized. Arial or similar font, non bold.
c. Material: Reflective, weather resistant material suitable for the environment (use UL - 969 as standard for weather rating). Durable adhesive materials meet this
requirement.
C.Marking Requirements on DC conduit, raceways, enclosures, cable assemblies, DC combiners and junction boxes:
1. Markings: Verbiage, Format and Type of Material.
a. Placement : Markings shall be placed every 10 feet on all interior and exterior DC conduits, raceways, enclosures, and cable assemblies,
at turns, above and for below penetrations, all DC combiners and junction boxes
b. Verbiage: CAUTION: SOLAR CIRCUIT Note: The format and type of material shall adhere to "V. V-3b, c" of this requirement.
c. Inverters are not required to have caution markings
1.Marking is required on all interior and exterior DC conduit raceways,enclosures,cable assemblies,and junction boxes,combiner boxes and disconnects.
2.The materials used for marking shall be reflective,weather resistant material suitable for the environment.
Minimum 3/8 "letter height; all upper case letters Arial or similar font; Red background with white lettering.
3.Marcking shall contain the words: WARNING : PHOTOVOLTAIC POWER SOURCE.
4.Marking shall be placed adjacent to the main service disconnect in a location clearly visible from the location where the disconnect is operated PV 3.0

Prior to the commencement of work, the contractor shall verify the existing roof and framing
conditions. Notify New@engineerinc.io of any Discrepancies prior to starting construction.
Prior to the commencement of work, the contractor shall inspect framing for any damage
such as water damage, cracked framing, etc. and notify New@engineerinc.io if any issues
are found.
These Plans are stamped for structural code compliance of the roof framing supporting the
