Understanding the National Electrical Code
The National Electrical Code (NEC) is a set of guidelines written to govern
the installation of wiring and equipment in commercial buildings and residential areas. These guidelines were developed to ensure the safety of
humans as well as property against fires and electrical hazards.
Understanding the National Electrical Code is important from the cable
manufacturer engineer and distributor, to the designer and installer.
Anyone involved in specifying cable to installation of cable should be
aware of the basics of the code.
In 1987, the National Electrical Code introduced some major changes that
had a major impact on the wire and cable industry. The code now has listing requirements for communication and power-limited circuit cable.
These requirements developed fire resistance levels for cable. The code
covers initiation of fire by electronic cable as well as flame spread characteristics of the cable.
Code Organization
The NEC code book is made up of nine chapters, with each chapter divided into separate articles pertaining to specific subjects. There are about
five articles that pertain to communication and power-limited cable. Each
article describes wire and cable construction, material use, cable markings, installation environments and applications.
Article Categories
There are four articles that cover communication, power-limited and
CATV wiring. There is another category that deals strictly with optical
fiber. The following is a list of those articles and the applications or systems they cover:
Article 725 - Class 1, Class 2, Class 3, Remote-control, Signaling and
Power-Limited circuits
Article 760 - Fire Protective Signaling Systems
Article 770 - Fiber Optic Systems
Article 800 - Communication Circuits
Article 820 - Community Antenna Television
Article Overviews
The NEC code can be somewhat confusing to the novice who has not
studied the code in depth. In most cases, within an article, a listing will
allow for a higher listed cable to be substituted for lower listed cable. Or
some listings from one article may be substituted for another article listing with possible restrictions. This section will briefly cover the basis of
the code to try to make things clearer for you. You should consult the NEC
book for exact specifications, wording, and accuracy of the code. This is
not in any way an exact excerpt from the code.
Article 725
Article 725 covers Class 1, Class 2, and Class 3 remote control and signaling cables as well as power-limited tray cable. Power-limited tray cable
can be used as a Class 3 or Class 2 cable. Cable listed multi-purpose, communications, or power-limited fire protective can be used for Class 2 and
Class 3 applications. A Class 3 listed cable can be used as a Class 2 cable.
Article 760
Article 760 covers power-limited fire protective cable. Cable listed as
power-limited fire protective cable can also be used as Class 2 and Class 3
cable. Cable listed as communications and Class 3 can be used as powerlimited fire protective cable with restrictions to conductor material and
type, gauge size and number of conductors.
Article 770
Article 770 covers fiber optic cable. This article covers three general types:
non-conductive, conductive, and composite. Non-conductive type refers
to cable containing no metallic members and no other electrically conductive materials. Conductive type refers to cable containing non-current
carrying conductive members such as metallic strength members, etc.
Composite type refers to cable containing optical fibers and current carrying electrical conductors. Composite types are classified according to the
type of electrical circuit that the metallic conductor is designed for.
Article 800
Article 800 covers multi-purpose and communication cable. Multi-purpose cable is the highest listing for a cable and can be used for communication, Class 2, Class 3, and power-limited fire protective cable.
Communication cable can be used for Class 2 and Class 3 cable and also
as a power-limited fire protective cable with restrictions.
Article 820
Article 820 covers community antenna television and RF cable. CATV
cable may be substituted with multi-purpose or communication listed
coaxial cable.
Designation and Environmental Areas
Not only does listing by circuit types have to be adhered to, but installation in various environments have to also be considered. The NEC has
designated four categories for various environments. These will be listed
from the highest to the lowest listing. A higher listing can be used as a
substitute for a lower listing.
Plenum - This listing is suitable for use in ducts, plenums, and other space
used for environmental air without conduit and has adequate fire-resistant and low-smoke producing characteristics. It can also be used for
applications below.
Riser - This listing is suitable for use in a vertical run, in a shaft or from
floor to floor, and has fire-resistant characteristics capable of preventing
the carrying of fire from floor to floor. It can also be used for applications
below.
General Purpose - This listing is suitable for general-purpose use, with the
exception of risers, ducts, plenums, and other space used for environmental air, and is resistant to the spread of fire. It can also be used for all applications below.
Restricted Applications - This listing is for limited use and is suitable for
use in dwellings and for use in raceways and is flame retardant. Restricted
use is limited to non-concealed spaces of 10 feet or less, fully enclosed in
conduit or raceway, or cable with diameters less than .25" for a residential
dwelling.
SPECIAL NOTES FOR COMMUNICATION CABLES:
* MULTI-CONDUCTOR CABLES WITH 24-16AWG CONDUCTORS CAN BE
RATED UL AND C(UL).
* MULTI-CONDUCTOR CABLES WITH 14-8AWG CONDUCTORS ARE
UL LISTED ONLY
* 10-8AWG SPEAKER CABLES ARE CL2 ONLY AND MUST INDICATE
AUDIO USE ONLY

Substitution Chart
The following chart explains the NEC cable hierarchy and will give you a
"picture" view of how this all fits together. The chart starts with the higher
listed cable at the top descending to the lower listed cable. Following the
arrows will allow you to find what listing can be substituted for others.
Also note restrictions in which case you will have to review the NEC code
in order to see if your cable is applicable.
Final Considerations
The National Electrical Code is widely accepted as the suggested regulations governing the proper installation of wire and cable in the United
States. The code is revised every three years to keep safety in the forefront
in wire and cable manufacturing and installation. Even though the code is
generally accepted, each state, county, city and municipality has the
option to adopt all of the code, part of the code, or develop one of its
own. The local inspectors have final authority of your installation.
Therefore, the NEC is a good reference when questions arise about the
proper techniques for a particular installation, but local authorities should
be contacted for verification.
When choosing cable for your installation there are four guidelines to follow to keep problems to a minimum:
1. The application and environment determines
which type of cable you can use and what
rating it should have. Make sure the cable
you’re installing meets the proper ratings for
your application.
2. If you will be substituting a cable with
another, you must have a cable that is rated
higher than what the code calls for. Check with your
local inspector as to what is allowed in your local area.
3. The NEC code is a general guideline that can
be adopted in whole or in part. Your local state, county,
city, or municipal approved code is what you must fol
low. Contact your local authorities for verification of the
code in your area.
4. The local inspector or fire marshal has the final authority
to approve or disapprove any installation of cable based
on the National Electric Code or on the local code.
If you remember these four guidelines, you should have fewer complications and headaches when installing cable in your area. Remember to
always work closely with your local authorities.

Calculating Conduit Capacity
One Cable Type in Conduit
The following information is to provide you with a quick and easy reference
for conduit fill requirements. This information is to be used as a general
guideline. Each installation has different restrictions for installation environments and/or local codes to follow.
The Conduit Capacity Chart provided on the following page is for applications when only one type of cable is to be used in a conduit. For example, if
you know the diameter of the cable you will be installing, use the cable O.D.
column, and find the exact or next largest diameter cable O.D.. Follow this
row over to the number of cables you need to install in a conduit. Then follow this column to the top of the chart and read the conduit size required
for the number of cables you need to install.
Multiple Types of Cable in One Conduit
If you will be mixing various cable diameters in a conduit, then this overall
chart does not apply. You will have to use the following guidelines to calculate the conduit fill requirements.
To determine the conduit size required for a particular installation of cable
follow these steps:
1. Square the O.D. of each cable and total the results.
2. Multiply the total by .7854*. This is the total area of
the cables in square inches.
3. From the Permissible Area row on the Conduit
Capacity Chart shown on the following page, select
the conduit size with an area equal to or greater -
than the total area you calculated.
* See Important Notes and
Installation Suggestions
** Permissible Area to be occupied (sq. in.) is
based on the NEC standard of 40% fill, which applies
to three or more non-lead covered cable installed in the
same conduit.
Important Notes and
Installation Suggestions
• A single cable is permitted to occupy 53% and two cables
are limited to 31% conduit fill. For a single cable use .5927 in step 2, for two
cables use 1.1034, and three or more cables use .7854.
• This chart is based on the maximum number of cable per mitted in con-
duit under the National Electrical Code, and is calculated on the area of the
cable with 40% of the
conduit filled. For conduit runs of 50 to 100 feet, the installed number
should be reduced by 15%, or use the next larger size conduit. If more than
two 90 degree bends are to be used in the conduit run, or if the run is to be
over 100 feet in length, insert a pull box.
• An anti-friction agent is recommended in pulling
operations.
*CAUTION: Select an anti-friction agent which is suitable for the cable
jacket material. The electronic characteristics of unjacketed cable may
change due to the application of anti-friction agents.
*
COLD ENVIRONMENT PRECAUTION: Due to the nature of PVC
compounds to become non-pliable when stored or handled in
ambient temperatures of 32 degrees F or less, we recommend the
following:
"Prior to installation, condition the cable for at least 24 hours at
room temperature to provide the best flex properties for ease of
installation."
• Permissible area chart does not apply to metallic and nonmetallic surface raceways; consult the NEC for recommendations.

THE INSTALLATION OF COMMUNICATION CABLE
IN THE SAME CONDUIT AS POWER CABLE.
Pulling Tensions
Under the stress of approximately 15,000 lbs./sq. in. annealed copper will
begin to permanently stretch. The table below lists the absolute maximum
recommended pulling tensions for conductor sizes. For multiple conductor
cable, multiply the appropriate value by the total number of conductors.
These pulling tensions must be equally distributed among the
conductors.
THESE LIMITS MUST NEVER BE EXCEEDED
EVEN MOMENTARILY!
DON’T JERK THE CABLE!
The electronic characteristics of a cable may change due to excessive ten-
sion and crushing.
