Purpose of electricity codes

Codes functions is to protect

persons and property emerginghazards the use of electricity.

Provide:

* Protection against electric shock

* Power failure protection

* Surge Protection



Standards are sets of rules or procedures for widespread use, or specifiedformally, and serving as a model of excellence or measure.

Integrated cables developed by specific

companies plans are called system

structured cable (SCS).



There are many other organizations nationally and internationally-typefire and building codes:



Best practices are forms of labour duties on the basis of the research thathelp users while performing tasks.



Manufacturers such as IBM and AT&T, standards had a profound effect inthe cable industry.



International Organization for Standardization. Promotes thedevelopment of standards and leads to international agreements,which are published as international standards.



The International Electrotechnical Commission. Global organization

that prepares and publishes international standards for alltechnologies in electronics, magnetism and electromagnetism.



American National Standards Institute, is

a private organization that identifiespublic and industrial requirements fornational approval standards.

Oversees the development of standards for: products,

services and processes.



It is a professional association in technical areas ranging from computerengineering and telecommunications to electrical energy, the aerospace andconsumer electronics.



In February 1980, the IEEE established a Committee to develop standardsfor networking, in particular for cabling and data transmission.



•802.11b (2,4 GHz / 11 Mbps)

•802.3u (Fast Ethernet 100 Mbps)

•802.11a (5,0 GHz / 54 Mbps)

•802.11g (2,4 GHz /54 Mbps)

•802. 11i (802.11 security)

To improve these standards, be must add one or more letters after thedecimal value:

•802.3ab (Gigabit Ethernet 1000Base-T on cable twisted pair Category5e)



This standard describes the series of digital bits that travel over thewire. IEEE 802.3 and variants get use of the cable to compete for him.



IEEE 802.3 defines the following cabling standards for LANs operate at aspeed of 10 or 100 Mbps, called 10Base or 100BASE baseband signalling:

•10Base2 – Use thinnet cable segment length 185 m, and is used with

physical bus topology and logical bus topology.



•10Base5 – Thinnet wiring used with maximum segment length of 500 m, and

is used with bus topology bus topology physical and logical.



•10Base-T– Used cable UTP category 3, 5, 5e or 6 with a segment length of

100 meters and is used with topology star physical or extended and logical bustopology.



•10Base-FL – Uses that operates at 850 nm multi-mode optical fiber cabling.

The maximum distance from a NIC to a hub is 2000 meters.



•100Base-TX – Used cable UTP category 5, 5e and 6 with a segment

length of 100 m, and is used with topology star physical or extended and

logical bus topology.



•100Base-FX – Using fiber optic multimode operates at 1300 nm segment

length wiring not specified maximum, depending on the use of a hub nox

class I or class II.



•1000Base-SX – Two optical fibers that

operate at 850 nm. (IEEE 802.3z)

•1000Base-CX – Four drivers special-

purpose shielded cable assembly (IEEE

802.3z)



•1000Base-TX – Uses four twisted

pairs of copper, category 6

•1000Base-T – Uses four twisted pairs of copper, category 5 or higher. (IEEE

802.3AB)



•(10GbE) Gigabit Ethernet 10 (IEEE data)

•1000Base-LX – Two optical fibers to 1300 nm. (IEEE 802.3z)



Apple introduced (1999) for the first time commercial products basedon the 802.11 standard. Currently, under the industrial nicknamewireless fidelity (Wi-Fi)



Electronic Industries Alliance and the Telecommunications IndustryAssociation are trade associations that develop structured cabling for voiceand data standards for the LAN.



Cabling installers currently used :

•TIA/EIA-568-A It is the standard

commercial building telecommunications

cabling.

•TIA/EIA-568-B It is the standard wiring.

This standard specifies requirements of

components and transmission according

to the media.



•TIA/EIA-568-B.1 Specifies a generic

commercial building telecommunications

cabling system that supports an

environment of several products and

suppliers.

•TIA/EIA-568-B.1.1 is an amendment that

applies to the radius of curvature of the

connecting cables (UTP, unshieldedtwisted-pair) and 4-pair unshielded twisted

pair (ScTP, screened twisted-pair) 4 pairs.



•TIA/EIA-568-B.3 Specifies the

components and transmission to a

fiber-optic cabling system

requirements.

•TIA/EIA-568-B.2 specifies cabling

components, transmission, system models

and measurement procedures required for testing twisted pair wiring.



•

TIA/EIA-570-A is the standardwiring for residential andcommercial telecommunicationsminors.

•TIA/EIA-569-A is the Commercial Building

Standard for Telecommunication and SpaceTours.



•TIA/EIA-607 is the standard requirements

Grounding Connection and CommercialBuilding Telecommunications.

•

TIA/EIA-606 is the governingstandard for the buildings commercialtelecommunications infrastructure andcable labeling



Family ANSI/TIA/EIA standards:

•ANSI/TIA/EIA-526, ANSI/TIA/EIA-526-7

and ANSI/TIA/EIA-526-14. They have astandardized method of test fiber opticcables.

•TIA/EIA-526-7 includes the loss of

optical power measurement in single-mode optical fiber cables installedplants.



•TIA/EIA-526-14A includes the

measurement of optical power loss inplants installed multimode fiber opticcables

•ANSI/TIA/EIA-598 describes the color

coding system used in fiber optic cableslarge (up to a couple dozen of fibers).



Association of Components, Electronic Assemblies and Materialsrepresents the electronics industry sector comprising manufacturersand suppliers.



Association of Consumer Electronics (CEA) to provide exclusive

information and unparalleled market research, networking opportunitieswith business advocates and leaders.



Government Association of Electronics and Information, studies the cable

market, enabling technologies, products and services electronically



Solid State Technology Association is the entity of the semiconductor

engineering standardization of EIA. Expanded to include integratedcircuits.



National Electrical Manufacturers Association, provides a forum for the

standardization of electrical equipment, which allows consumers to choose226 to electrical products safe, effective and compatible.



Rules on electricity focus on controllingelectricians are trained to avoiddangerous situations and comply witheach specified standards.



Compliance with certain codes varies by city or province. The departmentsgive approval for construction and project implementation.



We present a permitting process that includes fees and an allowance of time for hearings.

Local codes always take precedence over state codes, which in turn

take precedence over national codes.
