Chapter 13
Permitting and Inspection
Building Codes and Regulations •
Permitting • Inspection
Chapter 13 — Permitting and Inspection
Product standards,
installation codes, and
code enforcement are
separate but related
functions that result in
better and safer
installations.
Chapter 13 — Permitting and Inspection
There are several
types of UL marks,
each with a specific
meaning.
Chapter 13 — Permitting and Inspection
PV equipment may
bear the marks of
listing and certification
organizations other
than Underwriters
Laboratories.
Chapter 13 — Permitting and Inspection
Site drawings should
be provided with permit
applications indicating
locations and providing
descriptions of major
components.
Chapter 13 — Permitting and Inspection
Permit applications
must include either
a one-line or a
three-line electrical
diagram. Additional
electrical information
may be included as
a separate
document.
Chapter 13 — Permitting and Inspection
Specifications for PV modules, inverters, and other
equipment are required for code calculations and
compliance.
Chapter 13 — Permitting and Inspection
Descriptions and
drawings of the array
mounting design and
materials are used to
analyze the structural
integrity of the
structure and the array.
Chapter 13 — Permitting and Inspection
Building permits
include
information about
the construction
project and
inspections, and
must be posted
in a conspicuous
location.
Chapter 13 — Permitting and Inspection
Quality workmanship results in a neat and efficient
electrical installation.
Chapter 13 — Permitting and Inspection
Dedicated space is the
clear space reserved
around electrical
equipment for the
existing equipment and
potential future
additions.
Chapter 13 — Permitting and Inspection
Working space is the
clear space reserved
around electrical
equipment so that
workers can install,
inspect, operate, and
maintain the
equipment safely and
efficiently.
Chapter 13 — Permitting and Inspection
Rubber or plastic terminal covers are used to prevent
shorts across battery terminals.
Chapter 13 — Permitting and Inspection
PV module labels must
include terminal
polarity information
and ratings for voltage,
current, and power.
Chapter 13 — Permitting and Inspection
A label indicating the
operating current,
operating voltage,
maximum system
voltage, and shortcircuit current must be
displayed at the DC
disconnect of a PV
array.
Chapter 13 — Permitting and Inspection
Labels identifying the
PV system as a power
source and including
its maximum output
operating current must
be posted at the AC
disconnect of a PV
system.
Chapter 13 — Permitting and Inspection
PV systems with
batteries must have
labels indicating the
battery maximum
operating voltage,
equalization voltage,
and polarity of the
grounded circuit
conductor.
Chapter 13 — Permitting and Inspection
Single 120 V supply
panelboards must be
marked to prohibit
connection of multiwire
or 240 V branch circuit
loads.
Chapter 13 — Permitting and Inspection
Maintenance or
operation labels
are recommended
for detailing
nominal equipment
settings and
adjustment
procedures.
