Re: 2005 National Electrical Code
The 2005 National Electrical Code (NEC) is being forwarded to you for your consideration and
approval. Staff has worked with the Iowa City Homebuilders Association, the licensed
electricians and the Board of Appeals in the review of the NEC. The Board of Appeals has
unanimously recommended approval of the 2005 NEC. Staff also recommends approval of the
code.
Clarification of cable protection requirements in insulated concrete foam wall construction,
enforcement of the requirement to provide grounding to the footing or foundation steel and the
interpretation and enforcement of cable protection in unfinished basements were discussed
during the May 24, 2005 Board of Appeals meeting.
Attached is a more detailed summary of the local amendments and general changes to the
NEC.

Summary of the Iowa City Amendments
To the
2005 National Electrical Code
Changes "A" through "A.17" "Administration and Enforcement"
Change: Annex "G .... Administration and Enforcement" of thc 2005 NEC will be adopted,
amended and relocated to thc first section of thc adoptive code.
Commentary: Thc change helps maintain consistency with previously adopted Administrative
Sections of the Iowa City Electrical Code.
Change "B" Article 100 Definitions:
Definitions were modified to clarify requirements throughout the Iowa City Electrical Code.
Change "C" Section 210.52(A)(2) "Wall Space":
Change: This Section has been modified. An exception was added to further clarify
installation requirements for receptacles at open type "Guard Rail".
Commentary: The exception was added to further clarify when installation of
receptacles would be required with an open type railing installation. In these types of
applications a receptacle installed in the floor is used to meet the receptacle spacing
requirements. The exception does not require a receptacle to be installed in those
portions of living areas clearly used as walkways.
Change "D" Section 210.52{C )(2) "Island Counter Spaces":
Change: This Section has been modified to not require receptacles at kitchen islands,
however they will be permitted.
Commentary: The change tries to help eliminate hazards that occur when appliances are placed
on the island countertop. Receptacles that serve these countertops are usually installed below the
countertop surface. When appliances are plugged in, the cords for these appliances hangover the
countertops edge and create a serious hazard for small children. However receptacles that are
installed at these locations shall be required to meet the 2005 NEC.
Change "E" Section 210.52(C )(3) "Peninsular Counter Spaces":
Change: This Section has been modified to provide 2 options for the installation
requirements for receptacles at peninsular countertop areas.
Commentary: The change provides options. One of 2 options requires receptacle
placements to be installed above the kitchen countertop areas that they serve. The other
option will allow receptacle(s) to be installed above and or below the countertop areas
that they serve. This will leave some flexibility for the homeowners and contractors
during their kitchen design.
06/13/05
Change "F" Section 210.52(D) "Bathrooms":
Change: This Section has been modified to require bathroom receptacles to be installed
above thc rim level of bathroom countertops.
Commentary: The change added "above the rim" to the last sentence o£ the paragraph.
This will help maintain consistency with other receptacle installation requirements for
countertop type installations.
Change "G" Section 210.52(H) "Hallways":
Change: This Section has been modified to further clarify the requirements for thc
installation of receptacles at landings, and entryways of dwelling units, and common
areas of multi-family dwellings.
Commentary: The change clarifies the installation of general convenience receptacles in
common areas o£ apartment buildings. Further it clarifies installation requirements within
dwelling units.
Change "H" Section 210.52(I) "Water Conditioning Equipment":
Change: This Section has been modified by, adding a new section that requires a
receptacle to be installed for water conditioning equipment.
Commentary: The change requires a receptacle to be installed in areas where water-
conditioning equipment would normally sit. This is to help eliminate the use of extension
cords, in areas that are not normally habitable.
Change "I" Section 210.70(A)(1) "Switches for Habitable Rooms":
Change: This Section has been modified to clarify the location of required switches for
general lighting.
Commentary: The change clarifies that a switch shall be located within 5' of where you
enter a room, or a room that is accessible from grade, to operate the lighting outlets of
each habitable room(s).
Change "J" Section 225.19(D)(2) "Overhead Feeder & Branch Circuit Clearances":
Change: This Section has been modified to clarify the point, at which measurements will
be taken, to determine the height for overhead feeders and branch circuits over
projections, platforms, or places where they maybe reached.
06/13/05
Commentary: The change helps determine that a 3' vertical clearance of final spans
above, or within 3 ft (914 mm) measured horizontally of, platforms, projections, and
walking/and or sitting surfaces shall be maintained. These areas will be a nominal 6"
board width or wider or any other surface from which they might be reached.
Change "K" Section 230.9(B) "Overhead Service Entrance Conductors":
Change: This Section has been modified to clarify the point, at which measurements will
be taken, to determine the height for overhead conductor heights for Service Entrance
Conductors over projections, platforms, fire escapes, pomhes, balconies, ladders, stairs,
etc.
Commentary: The change helps determine that a 3' vertical clearance of final spans
above, or within 3 ft (914 mm) measured horizontally over projections, platforms, fire
escapes, porches, balconies, ladders, stairs, and walking/and or sitting surfaces shall be
maintained. These areas will also include areas constructed to be a nominal 6" board
width or wider or any other surface from which they might be reached.
Change "L" Section 230.50 "PVC for Protection of Service Entrance Conductors":
Change: This Section has been modified to limit the use of PVC type conduit for Service
Entrance Cable protection.
Commentary: The change limits the use of PVC for protection of Service Entrance
Conductors to 6'on the exterior of a building or structure. Metallic Raceways will offer
better protection for longer runs of"non-fused" conductors, and also will not be effected
by exposure to sunlight over long periods of time.
Change "M" Section 230.79 "Rating of Service Disconnecting Means":
Change: This Section has been modified to provide provisions to determine the
minimum size over current protective devices to be installed to protect Feeder or Service
Entrance Conductors installed to dwelling units.
Commentary: The change allows the given square footage of thc dwelling unit to be
served, to be used as the determining factor to size the Feeder / Service Entrance
Conductor over current device. The number of circuit spaces available in an electrical
panel is directly related to the Ampere rating of the Equipment itself. By requiring the
larger size Over-Current Device rating, the more spaces that will be available within the
electrical panels.
06/13/05
Change "N" Section 250.62 "Grounding Electrode Conductor Material":
Change: This Section has been modified to allow only copper to be used in the
Grounding Electrode System.
Commentary: The change was made to clarify that all portions of the Grounding
Electrode System shall be o£copper material.
Change "O' Section 250.64 "Grounding Electrode Conductor Installation":
Change: This Section was modified to clarify installation requirements for conductors
that are part of the Grounding Electrode System.
Commentary: The change requires that all conductors shall be of copper. Conductors
that are installed on the exterior of a building will require further protection when they
are exposed more than 24".
Change "P" Table 250.66" Min. of a #4 AWG. Grounding Electrode Conductor":
Change: This table has been modified to allow a #4 AWG conductor for the minimum
size electrode conductor to be installed to the copper water service of a dwelling.
Commentary: The change requires that a #4 AWG be required as a minimum size
conductor to be used. This will save the Homeowner / Property owner money and time if
and when they have the Service upgraded in the future. As far as the initial installation
cost, it is minimal price difference between #8 AWG and #4 AWG
Change "Q" Section 250.104{B) "Bondine of Metal Pil~in~ Systems":
Change: This Section has been modified to further explain sizing requirements for the
bonding conductor.
Commentary: The change clarifies that the size of the bonding jumper for all metal
piping systems will be determined by the rating of the Main or Feeder Over-current
device for the unit that is being served.
Change "R" Section 300.13{B) "Pigtails for Device Removal"
Change: This Section has been modified to require that the continuity of all conductors
shall not be dependent on devices and lamp-holders.
Commentary: The change requires that all conductors, for all types of branch cimuits,
that are terminated at devices or lamp holders shall be mechanically connected together
and then terminated to the device.
06/13/05
Change "S' Section 314.27(C) "Ceiling Fan Rated Boxes":
Change: This Section has been modified to require ceiling fan rated boxes to be installed
at all lighting outlet locations where a ceiling fan could be installed.
Commentary: The change requires that any ceiling opening used for lighting will require
a ceiling fan rated box to be installed at that location. The Amendment allows for
discretion for the areas not conducive for a ceiling fan installation. The electrical box that
supports the fan is the first step in assuring the safety of the public.
Change "T"~ Section 320.108 "AC Type Cable Grounding Construction Specs":
Change: This Section has been modified to require a Grounding Conductor to be
installed within the sheath of all AC type cables from the factory.
Commentary: The change requires that a separate grounding conductor be installed
within the sheath of all AC type cables. The internal grounding conductor will assist the
metallic sheath of the cable to facilitate thc operation of the breaker.
Change "U"~ Section 330.108 "MC Type Cable Grounding Construction Specs":
Change: This Section has been modified to require a Grounding Conductor to be
installed within the sheath of all MC type cables from the factory.
Commentary: The change requires that a separate grounding conductor be installed
within the sheath of all MC type cables. The internal grounding conductor will assist the
metallic sheath of the cable to facilitate the operation of the breaker.
Change "V"~ Section 334.10 NM ,type Cable "Uses Permitted":
Change: This Section has been modified to allow NM type cable to be installed only in
Residential Type Occupancies as determined by the Building Code.
Commentary: The change allows the use of NM Type Cable ("Romex" / "Housewife")
to only be installed in Residential Occupancies. Residential type occupancies do not alter
their electrical systems without major remodels. Commercial type occupancies using
other types of wiring methods, such as a raceway method, can be altered without major
structural remodeling.
Change "W"~ Section 348.12 "Flexible Metal Conduit Uses":
Change: This Section has been modified to limit the use of Flexible Metal Conduit in
concealed areas in new construction.
Commentary: The change restricts the use of flexible metal conduit to be concealed in
walls, and ceiling assemblies (including above drop ceilings) in lengths greater than 6'
06/13/05
unless approved prior to the installation. It shall be permitted in existing construction
where fished in undisturbed walls or ceiling assemblies.
Change "X"I Section 518.4(B) "Non-Rated Construction in Assembly Occupancy":
Change: This Section has been modified to eliminate the use of NM type cable in an
Assembly Occupancy.
Commentary: The change does not allow the use of NM cable at all in an Assembly
Occupancy. This also maintains consistency with other requirements for NM type
installations.
Change "Y" Section 680.41 "Emergency Switch for Private Hot Tubs and Spas":
Change: This Section has been modified not to require "Emergency Shut-off' switches
for all single-family dwellings.
Commentary: The change clarifies that "Emergency Shut-off Switches" for spas and hot
tubs will not be required for single family dwellings or those Hot Tubs & Spas that are
not for use by the general public.

Summary of General Changes
To the
2005 National Electrical Code
210.8(B)(4)&(5) ... GFCI Protection Requirements for "Other Than Dwellin~
Units".
2005 National Electrical Code has added new requirement to cover outdoor receptacles at
other than dwelling units.
Receptacles that are installed outdoors and are accessible to the public are required to be
GFCI protected. In addition, receptacles installed outdoors for heating, air conditioning,
and refrigeration equipment will be required to be GFCI protected.
* 210.12 Arc-Fault Circuit Protection Requirementsl 210-18 Guest Rooms & Suites:
2005 National Electrical Code has added additional ways for providing AFCI protection
for dwelling unit bedrooms, a AFCI Breaker can be installed or the protection can come
from a AFCI device (receptacle). If an AFCI device is to be installed to provide the
protection, its location in the circuit is critical.
January 1st of 2008 all AFCI breakers and devices will be required to be of the
combination type. These breakers and Devices will be required to be tested and listed to
be able to recognize a "Series" and or a "Parallel" type of arc.
210.18 Now requires that the same type of AFCI protection will also be required for
Guest Rooms and Suites.
250.50 Grounding Electrode System:
2005 National Electrical Code has removed the word "available" from the Section
250.50. By deleting "available" it has clarified that all Electrical Services shall be
bonded to the steel located in the within the footing. In addition there was an exception
added. The exception does not require a connection be made to the footing steel on
existing buildings or dwellings during remodeling or alterations.
314.16 (B)(1) Conductor Allowances for Looped Conductors in a Box:
Unbroken loops of conductors that are installed within a junction box will have to be
added to the box fill calculation. If the loop contains not less than twice the amount of
free conductors (not < 12") an additional count of 2 conductors will be added to the
calculation.
06/13/05
* 334.15 (B) Exposed NM Cable; Protection from Physical Damage:
2005 National Electrical Code has added verbiage to address installations of NM cable in
shallow chases in masonry, concrete, or adobe. This would include those types of
installations located in Foam Foundation type homes. It will be required to protect these
types of cable installations with one of the following means; Rigid Metal Conduit,
Intermediate Conduit, Electrical Metallic Tubing, or Scheduled 80 PVC, or 1/16th plate
the length of the cable.
* 334.15 (C) Exposed NM Cable; Unfinished Basement:
2005 National Electrical Code has addressed thc requirement for protection of NM cables
installed in unfinished basements. Cables installed in walls in an unfinished basement
shall be protected by a listed conduit system, and shall be installed to avoid abrasion
damage where the cable enters the conduit system. Cables installed in a wall entering an
Electrical Panel shall be protected per 312.5 (C) for Cabinets, Cutout Boxes, and Meter
Enclosures.
408.4 Circuit Directory or Circuit Identification:
2005 National Electrical Code has addressed a long time problem. All circuits and circuit
modifications shall be legibly identified as to its clear, evident, and specific purpose. Thc
Panel Schedules for all panels will have to contain more detail to what each overcurrcnt
device protects and controls.
422.51 Cord and Plug Connected Vending Machines:
2005 National Electrical Code does require as of January 1st, 2005 all vending machines
will require GFCI protection as part of the vending machine itself. Vending machines
prior to having this requirement shall be attached to a GFCI protected Receptacle.
Article 605:605.6 Fixed-Type Partitions; 605.7 Freestanding-Type Partitions;
2005 National Electrical Code has added a new requirement to the installation of Fixed
and Freestanding - Type Office Partitions. The wiring method is still required to be one
of the methods allowed in Chapter 3 of the 2005 NEC. The new requirement is, when
partitions are connected to a multi-wire branch circuit that there shall be a means to
disconnect all of the ungrounded "hot" conductors simultaneously.
680.26 Equipotential Bonding for Swimming Pools: Sections 680.26 (B)(1) & 680.26
2005 National Electrical Code has clarified how thc Equipotcntial Bonding (Grounding)
Grid shall be installed. The addition of the "Alternate Means" to Part C, has given
direction on how to eliminate Voltage Gradients.
06/13/05
* Article 695 Fire Pumps: 695.4(B)(2) Disconnecting Means requirements:
2005 National Electrical Code has added a number (3) to the list of requirements for the
disconnecting means for Fire Pumps.
(3) Can not be located within equipment that feeds loads other than the fire pump.
This now has made it clear that the disconnecting means for Fire Pumps shall be located
in switch gear/enclosure completely separate from all other equipment.
