laboratory as set forth in the list thereof maintained by the Idaho division of building
safety, electrical bureau; or
b. Approved by the city electrical inspector, provided that such material, device, fitting,
equipment, apparatus, fixture, and/or appliance equipment is installed under an
electrical permit issued pursuant to this chapter and conforms to industry and/or NEC
standards. Where in the judgment of the city electrical inspector a field evaluation is
UPDATE TO LOCAL AMENDMENTS TO NEC PAGE 1 OF 5
necessary to determine the compliance of the material, device, fitting, equipment,
apparatus, fixture, and/or appliance equipment with industry and/or NEC standards,
such field evaluation shall be completed by an accredited electrical product testing
laboratory as set forth in the list thereof maintained by the Idaho division of building
safety, electrical bureau. Such approval shall not be required for products that are
certified/listed on the list thereof maintained by the division of building safety,
electrical bureau.
Sb. A new provision shall be added as follows:
Temporary Uses.
a. Any and all electrical circuits and/or wiring which are in, upon, or used within a
temporary structure and/or which are at, for, or used by a temporary use shall be
protected by ground fault circuit interrupter protection (GFCI) at the source. This shall
include, but shall not be limited to, all cords that are located in, upon, or across open
areas, parking areas, walkways, planters, drive aisles, and/or inside any portion of a
temporary structure.
b. Any and all lighting bulbs which are in, upon, or used within a temporary structure
and/or which are at, for, or used by a temporary use shall be completely enclosed by
glass fixture lens. Any and all fluorescent lamps which are in, upon, or used within a
temporary structure and/or which are at, for, or used by a temporary use shall be
completely enclosed in tube guards.
c. Any and all temporary or extension cords used for power in, upon, at, for, or used by
a temporary structure and/or a temporary use shall be in good condition and
undamaged, and shall have no splices or open conductors.
6~. Article 210.12 shall be deleted and replaced with the following language:
Arc-Fault Circuit-Interrupter Protection.
a. Definition: Arc-Fault Circuit Interrupter. An arc-fault circuit inteiTUpter is a device
intended to provide protection from the effects of arc faults by recognizing
characteristics unique to arcing and by functioning to de-energize the circuit when an
arc fault is detected.
b. Dwelling Unit Bedrooms. All 120-volt, single phase, 15- and 20-ampere branch
circuits supplying outlets installed in dwelling unit bedrooms shall be protected by a
listed arc-fault circuit interrupter, combination type installed to provide protection of the
branch circuit.
c. Exception: The location of the arc-fault circuit interrupter shall be permitted to be at
other than the origination of the branch circuit in compliance with both of the following:
(1) The arc-fault circuit interrupter installed within six (6) feet of the branch
circuit overcuiTent device as measured along the branch circuit conductors.
(2) The circuit conductors between the branch circuit overcunent device and the
arc-fault circuit interrupter shall be installed in a metal raceway or a cable with a
metallic sheath.
7~. Article 680.26 shall be deleted and replaced with the following language:
Bonding.
a. Performance. The bonding required by this section shall be installed to eliminate
voltage gradients in the pool area as prescribed. This section does not require that the 8
UPDATE TO LOCAL AMENDMENTS TO NEC PAGE 2 OF 5
AWG or larger solid copper bonding conductor be extended or attached to any remote
panelboard, service equipment, or any electrode.
b. Bonded Parts. The following specified parts shall be bonded together:
(1) Metallic Structural Components. All metallic parts of the pool structure,
including the reinforcing metal of the pool steel, coping stones, and deck, shall
be bonded. The usual steel tie wires shall be considered suitable for bonding the
reinforcing steel together, and welding or special clamping shall not be required.
These tie wires shall be made tight. If reinforcing steel is effectively insulated by
an encapsulating nonconductive compound at the time of manufacture and
installation, it shall not be required to be bonded. Where reinforcing steel is
encapsulated with anon-conductive compound, provisions shall be made for an
alternate means to eliminate voltage gradients that would otherwise be provided
by unencapsulated, bonding reinforcing steel.
(2) Underwater Lighting. All forming shells and mounting brackets or no-niche
luminaries/fixtures shall be bonded unless a listed low-voltage lighting system
with nonmetallic forming shells not requiring bonding is used.
(3) Metal Fittings. All metal fittings within or attached to the pool structure shall
be bonded. Isolated parts that are not over 100 mm (4 inches) in any dimension
and do not penetrate into the pool structure more than 25 mm (1 inch) shall not
require bonding.
(4) Electrical Equipment. Metal parts of electrical equipment associated with the
pool water circulating system, including pump motors and metal parts of
equipment associated with pool covers, including electric motors, shall be
bonded. Metal parts of listed equipment incorporating an approved system of
double insulation and providing a means for grounding internal non-accessible,
non-cui-~•ent-carrying metal parts shall not be bonded. Where adouble-insulated
water-pump motor is installed under the provisions of this rule, a solid 8 AWG
copper conductor that is of sufficient length to make a bonding connection to a
replacement motor shall be extended from the bonding grid to an accessible
point in the motor vicinity. Where there is no connection between the swimming
pool bonding grid and the equipment grounding system for the premises, this
bonding conductor shall be connected to the equipment grounding conductor of
the motor circuit.
(5) Metal Wiring Methods And Equipment. Metal-sheathed cables and
raceways, metal piping, and all fixed metal parts except those separated from the
pool by a permanent baiTier shall be bonded that are within the following
distances of the pool:
(a) Within 1.5 m (5 ft) horizontally of the inside walls of the pool.
(b) Within 3.7 m (12 ft) measured vertically above the maximum water
level of the pool, or any observation stands, towers, or platforms, or any
diving structures.
c. Common Bonding Grid. The parts specified in subsection (b), above, shall be
connected to a common bonding grid within a solid copper conductor, insulated,
covered, or bare, not smaller than 8 AWG. Connection shall be made by exothermic
welding or by pressure connectors or clamps that are labeled as being suitable for the
purpose and are of stainless steel, brass, copper, or copper alloy. The common bonding
grid shall be permitted to be any of the following:
(1) The structural reinforcing steel of a concrete pool where the reinforcing rods
are bonded together by the usual steel tie wires or the equivalent.
UPDATE TO LOCAL AMENDMENTS TO NEC PAGE 3 OF 5
(2) The wall of a bolted or welded metal ool.
p
(3) A solid copper conductor, insulated, covered, or bare not smaller than
8
AWG.
(4) Rigid metal conduit or intermediate metal conduit of brass or other iden i
t fled
corrosion-resistant metal conduit.
d. Connections. Where structural reinforcing steel or the walls of bolted or
welded
metal pool structures are used as a common bondin rid for nonelectrical art
. g g p s, the
connections shall be made in accordance with article 250.8.
e. Pool Water Heaters. For pool water heaters rated at more than 50 am eres that h
p ave
specific instructions regarding bonding and groundin , onl those arts desi nat
g Y p g ed to be
bonded shall be bonded, and only those parts desi nated to be rounded shall
g g be
grounded.
8~. Annex H of the NEC, also known as article 80, is not ado ted.
p
Section 2. That all ordinances, resolutions, orders, or arts thereof or in conflict '
p with this
ordinance are hereby voided.
