This letter is in response to the plan review dated June 16, 2016. Please find enclosed the following
items:
1. (1) set of Solar (Redlined) Plan
2. (1) set of Correction List with Responses
3. (2) sets of Revised Plan Sets
4. (2) set of Racking System Analysis
5. (2) sets of Structural Calculations
6. (1) set of Assessors Site/Floor Plan
The items listed on the "NON-RESIDENTIAL PLAN CHECK CORRECTION LIST" are addressed as
follows:
SECTION A - GENERAL
1) Provide on each sheet of resubmitted Plans and cover sheet of bound Calculations the preparer's name
and telephone number and wet -signature. If the preparer is a licensed architect or engineer, all documents
prepared by that licensed individual shall also bear his/her stamp as prescribed by California Business and
Professions Code '5536. Resubmittals will not be accepted with signatures missing.
Response: Please see project engineers wet -stamp and signature on each sheet of
resubmittal.
SECTION B — SOLAR
I. General
1) Reconcile noted information shown on single line diagram. See 1st review redlined plan. Please provide a
response for each item, either on returned redlined plan or in letter.
90°C WET RATED CONDUCTOR REQUIRED
Response:
TC-ER cable has been changed to type THHN/THWN-2. Please see revised wire types on
PV3.00 and wire sizing table on PV3.10.
TEMPERATURE DERATE (SPECIFY DISTANCE TO ROOF)
Response:
Temperature derate has been adjusted to reflect a maximum ambient temperature
of 1220F (500C). A temperature adder of 30°F (17°C) has been added to reflect a height of 3.511-
12" off of the roof. Please see revised calculations on PV3.10 and General Note #2 on PV3.00.
II. Circuit Requirements
1) Overcurrent devices shall be sized to carry not less than 125% of the maximum currents as calculated in
690.8(A). (CEC §690.8(B)(1)) The overcurrent devices specified on plan do not appear to be corrected
accordingly, see 1st review redlined plans for additional information.
Response:
The TenKSolar Titan 410W module has an internal current limiting device (as defined in CEC
240.2) at the module output, where the DC output conductors are terminated to. Due to this
current limiting device, this circuit is not considered "PV Source Circuit" whose output could
be varied and therefore a 125% multiplier is not required. Please see response to comment #2
below for further explanation of DC output of solar modules.
2) Circuit conductors shall be sized to carry the large of 125% of the maximum currents calculated in 690.8(A)
without any additional correction factors for conditions of use or 100% of the maximum current after
conditions of use have been applied. (CEC §690.8(B)(1)) Provide conductor sizing schedule showing
compliance with either option, including fully specifying temperature and conduit fill deratings.
Response:
The DC output of the solar modules is current -limited and voltage -controlled via the integral
power electronics. The output is therefore not a typical PV source circuit as there is no
"common connection point" of the DC system. The operating current of these DC output
circuits is driven by the setpoint of the inverter, and the maximum DC output circuit current is
limited to the maximum input current of the inverter. This is similar to a stand-alone system as
described in 690.8(A)(4). As such, the maximum operating current of the DC output circuits is
15A (maximum input current of the inverter).
Per CEC 690.8 (B), PV circuit conductors shall be sized to carry not less than the larger of
690.8[B][1] or 690.8[B][2].
Per 690.8[B][1] —
(15A per inverter) x (6 inverters) x (125%) = 112.5A
Per 690.8[B][2] —
Ambient temperature correction factor based on 50C per CEC Table 310.15(B)(2)(a)
(15A per inverter) x (6 inverters) / (0.82 correction factor) = 109.76A
Please see revised DC output circuit wiring listed as #2 CU on PV3.01, PV3.02 and PV3.10. The
specified #2 CU PV-Wire conductor has a free -air ampacity of 170A/190A (75°F/90°F)
Please see revised wire sizing schedule on PV3.10, showing columns for "Temperature De -
'rate" and "Current -Carrying Conductor De -Rate".
3) Photovoltaic source circuit, photovoltaic output circuit, inverter output circuit, and storage battery circuit
conductors and equipment shall be protected in accordance with the requirements of Article 240. Circuits
connected to more than one electrical source shall have overcurrent devices located so as to provide
overcurrent protection from all sources. (CEC §690.9(A)) Fuse rating of photovoltaic panels not found,
please provide verification that the panels may be paralleled to the ampacities proposed.
Response:
See explanation of DC output circuit calculation in response to comment #2. The maximum
current of the branch conductors, as calculated in the previous response, is 112.5A. These
conductors are protected by the (6) 20A/1P breakers in the DC combiner box per 240.4(B) and
240.4(D)(7). Please see wiring diagrams on PV3.01 and PV3.02 for OCPD sizes.
4) Branch circuit or supplementary type overcurrent devices shall be permitted to provide overcurrent
protection in photovoltaic source circuits. The overcurrent devices shall be accessible but shall not be
required to be readily accessible. (CEC §690.9(C)) Accessible (as applied to equipment) is admitting close
approach, not guarded by locked doors, elevation, or other effective means — the proposed location of DC
combiner/OCPD under fixed arrays does not comply as it is "guarded" by other equipment.
Response:
The AC disconnect for each inverter group is located at the end of row containing the
inverters. The DC disconnects in the combiner box are located roughly 36 inches into the
array at the same location. The pin holding the module in place at the peak of the row can be
removed with no tools, allowing the module that spans over the AC disconnect and combiner
box to be lifted for further access to the equipment below. Both pieces of equipment are
accessible from the edge of the array. Please see TenKSolar installation guide for more
information.
IV Ming Methods
1) All raceway and cable wiring methods included in the California Electrical Code and other wiring systems
and fittings specifically intended and identified for use on photovoltaic arrays shall be permitted. (CEC
§690.31, Chapter 3) Provide a conductor sizing table, including conduit sizing, to justify the proposed
installation. Additionally, see 1st review redlined plan sheet PV3.01, and clarify how the proposed
Redundant Inverter Bus system complies with the general requirements of the Electrical Code.
Response:
Please see revised wire sizing schedule on PV3.10, with column added for "Conduit Size".
2) Aluminum conductors are permitted only if size 1/0 or larger, and only to feed main or sub -panels. All other
current carrying conductors shall be copper. (LQMC §8.03.040)
Response:
All current carrying conductors smaller than size 1/0 have been revised to be copper. Please
see revised wire material and sizing on PV3.00 and PV3.10.
3) No conductor shall be used in such a manner that its operating temperature exceeds that designated for
the type of insulated conductor involved. (CEC §310.15(A)(3)) With the high heat areas where photovoltaic
conductors are installed, please specify the use of 90°C rated conductors.
Response:
All conductors have been spec'd as 900C rated. Please see revised wire types on PV3.00 and
PV3.10.
4) Ampacities for ambient temperatures other than those shown in the ampacity tables shall be corrected in
accordance with Table 310.15(B)(2)(a) or (b). (CEC §310.15(B)(2)) Design of permitted conductor
ampacities shall be calculated with ambient temperatures in the 114-122°F range. Revise calculations
based on this range, including the following corrections as necessary.
Response:
Conductor ampacities have been revised to be calculated with ambient temperatures in the
114-122°F range. Please see revised wire sizing on PV3.00 and PV3.10.
5) Where the number of current -carrying conductors in a raceway exceed three (3) the allowable ampacity of
each conductor shall be reduced as shown in Table 310.15(B)(3)(a). (CEC §310.15(B)(3)) Provide verification
the proposed 4-wire, 3-phase, wye circuit complies with 310.15(B)(5)(c), or revise calculations to include
derating to (4) current carrying conductors.
Response:
Please see revised calculations and wire sizing schedule on PV3.10, including a 0.8 derate for
the (4) current -carrying conductors within the TC-ER cable.
6) Conduits exposed to sunlight on rooftops, where conductors or cables are installed, the adjustments shown
in Table 310.15(B)(3)(c) shall be added to the outdoor temperature to determine the applicable ambient
temperature for application of the correction factors in Table 310.15(B)(2)(a). (CEC §310.15(B)(3)(c)) Adjust
conductor sizes accordingly.
Response:
Per CEC 310.15(B)(3)(c), the ambient temperature adjustment factor applies when "raceways
or cables are exposed to direct sunlight on or above rooftops." Since the cable tray spec'd
has a shade cover that will block the cables from direct sunlight, and since the cable tray does
not fall into the category of "raceway", no ambient temperature adjustment factor is
necessary.
V. Grounding
1) Photovoltaic systems having do circuits and ac circuits with no direct connection between the do grounded
conductor and ac grounded conductor shall have a do grounding system per 690.47(B). Provide additional
information on plans to clearly demonstrate the requirements of the proposed Combined Direct -Current
Grounding Electrode Conductor and Alternating -Current Equipment Grounding Conductor. See below, the
information on the grounding diagram only locally shows the requirement for unspliced or irreversibly spliced,
and with the proposed equipment (subpane/s, disconnects, etc.) this would not include connections with bus
bars. Additionally, verify that all proposed sizes are compliant with increased conductor sizing for voltage
drop.
a) An unspliced, or irreversibly spliced, combined grounding conductor shall be run from the marked
do grounding electrode conductor connection point along with the ac circuit conductors to the
grounding busbar in the associated ac equipment. This combined grounding conductor shall be
the larger of the sizes specified by 250.122 or 250.166 and shall be installed in accordance with
250.64(E).
b) Specify Equipment Grounding Conductor and demonstrate compliance with the requirements of
CEC §690.43 on plan. Where ungrounded conductors are increased in size, equipment
grounding conductors shall be increased in size proportionately according to the circular mil area
of the ungrounded conductors. (CEC §250.122(B))
Response:
Please see revised system grounding diagram on PV4.00. Per 690.47(C)(3) the CU combined
DC GEC / AC EGC will be sized in accordance with 250.166. NEC 2014 permits the maximum
size of the DC GEC to be #3/0 CU. This DC GEC will be run from the ground bus at the facility's
main switchboard to the PVDP, where it will be irreversibly spliced to a #8 CU and run to the
ground bus at the DC combiner box at each inverter assembly. A #3 CU AC EGC will be
spliced off of the GEC and bonded to the ground bus of each piece of equipment until the DC
combiner box.
2) Specify Equipment Grounding Conductor and demonstrate compliance with the requirements of CEC
§690.43 on plan. Where ungrounded conductors are increased in size, equipment grounding conductors shall
be increased in size proportionately according to the circular mil area of the ungrounded conductors. (CEC
§250.122(B))
Response:
TenKSolar Racking system has evaluated for bonding continuity from module frame to
mounting rails, allowing the racking to serve as an integrated DC EGC. Equipment grounding
conductors have been increased in size proportionally according to the size of the
ungrounded phase conductors per 250.122(A). Please see revised EGC wire sizing on PV3.10
and attached TenKSolar installation manual.
SECTION E - MISCELLANEOUS COMMENTS
Red marks on Plans, even if not specifically mentioned in this list, indicate items needing correction. Revise
Plans as necessary and provide written response, noting where correction can be found.
PV3.01
"SOURCE DC -
(16) x 7.5A = 120A;
120A x 1.25 = 150A (690.8(B)(1))"
Response:
Please see response to comment in Section B � ll. Circuit Requirements -:� "I) Overcurrent
devices shall be sized to carry not less than..." and Section B ll. Circuit Requirements 4 "2) Circuit
conductors shall be sized to carry the larger of..."
Per 690.8[B][1] —
(15A per inverter) x (6 inverters) x (125%) = 112.5A
"OUTPUT DC -
(6) x 20A OCPD = 120A (Does not comply with 690.8(B)(1)"
Response:
See response to previous comment. Maximum output current of branch circuit is 112.5A and
is being protected by 120A combined OCPDs, compliant with 690.8(B)(1).
"OUTPUT DC -
20A OCPD > 15A Max per MPP7
Response:
The maximum input short circuit current of the inverter is 20A. Although each MPPT can
accept up to 15A, collectively they can only accept at total of 20A. Please see attached data
sheet for LS700 inverter.
"OUTPUT AC -
Qty(4) Inverter @ 2.53A out = 10.12A;
25A > 10.12 x 1.25 (Does not comply with 690.8(B)(1)"
Response:
The 25A circuit breakers located in the AC disconnect are providing a disconnecting means
for the inverter group, but not to provide overcurrent protection. The circuit breakers located
in the PVDP are providing overcurrent protection to the inverter groups and are sized
accordingly. The conductors labeled "AC Disconnect Whip" spanning between the inverter
bus and the AC disconnect have been sized per 690.8(B)(1) so that in the event of an
overcurrent situation, the circuit breaker will trip before the conductors fail. Please see
revised calculations on PV3.10.
PV3.10
"Use specific temperature data per historical highs (Typically in the 114°F-122°F)"
Response:
Ambient temperature used for calculations has been revised to 122°F(50°C). Please see
revised calculations on PV3.10.
"Where do these values come from" *Pointing to 0.95 CCC value*
Response:
CEC 392.80(A)(1)(b) states that "where cable trays are continuously covered for more than
1.8m (6ft) with solid unventilated covers, not over 95 percent of the allowable ampacities of
Table 310.15(B)(16) and Table 310.15(B)(18) shall be permitted for multiconductor cables."

AJ,
I was forwarded this email late this afternoon regarding the calculations for the Cinemark. Regarding the second issue
requesting loading calculations for installed ballast anchorage required, did you receive the attached
calculations? Please note that these calcs were modified from the original set of calculations. On the bottom of page 1,
there is a table which shows the weight of each individual array. The heaviest array is array 6, which weighs 8 psf. I
therefore increased the weight used for the calculations to 10 psf, just so there wouldn't leave any doubt that the
existing structure works. Reference the screenshots:

Judging by the capacities of the joists and girders, with the governing element being the 221<4 joists spanning between
lines D-G/1-5, this building can support a total of 47 psf, which is still 12 psf more capacity than what is required to
support the 10 psf of solar array. In short, this building has more additional capacity than any of the 200+ buildings I
have permitted for solar.
