§ 10-86. National Electrical Code adopted.

The National Electrical Code, 2012 Edition, including recommended local amendments which are attached hereto as exhibit A, is herewith adopted by reference as the electrical code of the city and made part of this Code. A copy of this code, with approved amendments, shall be kept on file in the office of the city secretary for reference and inspection.

(1)

Interpretation of the National Electrical Code, 2012 Edition. Any requirements considered necessary for the safety, strength or stability of any proposed building or structure, or for the safety or health of the occupants thereof, shall be in accordance with the provisions of the National Electrical Code, 2012 Edition, or any amendments, specifications or revisions, thereto, and the meaning and intent of such provisions shall be interpreted and determined by the building official, subject to the right and appeal contained in any of such codes, if any.

(2)

Amendments to the National Electrical Code, 2012 Edition. The sections of the National Electrical Code, 2012 Edition that are changed, added or deleted are as follows:

a.

Section 500.8(A)(3) changed to read as follows:

500.8 Equipment. Articles 500 through 504 require equipment construction and installation that ensure safe performance under conditions of proper use and maintenance.

FPN No. 1: It is important that inspection authorities and users exercise more than ordinary care with regard to installation and maintenance.

FPN No. 2: Since there is no consistent relationship between explosion properties and ignition temperature, the two are independent requirements.

FPN No. 3: Low ambient conditions require special consideration. Explosion proof or dust-ignition proof equipment may not be suitable for use at temperatures lower than -25°C (-13°F) unless they are identified for low-temperature service. However, at low ambient temperatures, flammable concentrations of vapors may not exist in a location classified as class I, division 1 at normal ambient temperature.

(A)

Suitability. Suitability of identified equipment shall be determined by one of the following:

(1)

Equipment listing or labeling.

(2)

Evidence of equipment evaluation from a qualified testing laboratory or inspection agency concerned with product evaluation.

(3)

Evidence acceptable to the authority having jurisdiction such as a manufacturer's self-evaluation or an engineering judgment signed and sealed by a qualified registered professional engineer.

FPN: Additional documentation for equipment may include certificates demonstrating compliance with applicable equipment standards, indicating special conditions of use, and other pertinent information.

b.

Section 505.7(A) changed to read as follows:

505.7 Special Precaution. Article 505 requires equipment construction and installation that ensures safe performance under conditions of proper use and maintenance.

FPN No. 1: It is important that inspection authorities and users exercise more than ordinary care with regard to the installation and maintenance of electrical equipment in hazardous (classified) locations.

FPN No. 2: Low ambient conditions require special consideration. Electrical equipment depending on the protection techniques described by 505.8(A) may not be suitable for use at temperatures lower than -20° Celsius (-4° Fahrenheit) unless they are identified for use at lower temperatures. However, at low ambient temperatures, flammable concentrations of vapors may not exist in a location classified class I, zones 0, 1, or 2 at normal ambient temperature.

(A)

Implementation of Zone Classification System. Classification of areas, engineering and design, selection of equipment and wiring methods, installation, and inspection shall be performed by qualified registered professional engineer.

c.

Section 680.25(A) changed to read as follows:

680.25 Feeders. These provisions shall apply to any feeder on the supply side of panelboards supplying branch circuits for pool equipment covered in part II of this article and on the load side of the service equipment or the source of a separately derived system.

(A)

Wiring Methods. Feeders shall be installed in rigid metal conduit, intermediate metal conduit, liquidtight flexible nonmetallic conduit, rigid polyvinyl chloride conduit, or reinforced thermosetting resin conduit. Electrical metallic tubing shall be permitted where installed on or within a building, and electrical nonmetallic tubing shall be permitted where installed within a building, or nonmetallic-sheathed cable or type SE cable shall be permitted where installed within or on the building served. Aluminum conduits shall not be permitted in the pool area where subject to corrosion.

Exception: An existing feeder between an existing remote panel board and service equipment shall be permitted to run in flexible metal conduit or an approved cable assembly that includes an equipment grounding conductor within its outer sheath. The equipment grounding conductor shall comply with 250.24(A)(5).
