Pakistan Cables

CABLES&

TABLESBased on BS 7671:2001

On the occasion of 50th Anniversary of Pakistan Cableswe are proud to present the latest and completely revised version of“CABLES AND TABLES” which is a handy reference for our manyfriends concerned with the installation of electrical equipment.

This booklet has a long history as it was first publishedby Pakistan Cables in 1954 and thereafter it was regularlyupdated and printed on various occasions in 1967, 1970 (the Metricversion), 1985, 1992 and 1999.

This latest version includes revisions and additions based onBS 7671:2001 “Requirements for Electrical Installations”IEE Wiring Regulations, Sixteenth Edition. The main departure fromprevious practice, and we believe, the fact that will increase the utilityUrdu translation to the text matter.

We would also like to put on record our acknowledgmentand gratitude to Engineer Wali Jan of M/s. Wali Jan Associates, inputting this together this latest edition of Cables & Tables. It was notonly his technical expertise, but also dedication to the project whichdeserves particular mention.

We would also like to reiterate our policy of not compromisingon quality for which our products are much acclaimed.

We welcome your valued suggestions for further improvementin the publication.

Trusted not to Compromise

Pakistan Cables Limited, the country’s oldest and most reputable cable manufacturer, was established50 years ago in 1953 under the sponsorship of BICC pIc of United Kingdom and the Chinoy family. In thesubsequent five decades, Pakistan Cables has earned a reputation for itself as a market leader in the industryand as a company that does not compromise on quality. As a result, the company has gained a position asbeing the premier cable manufacturer in the country.

Pakistan Cables is a Public Limited Company and was listed on the Pakistan Stock Exchange as early as 1956,when only 51 companies in Pakistan were public. The company has repeatedly received awards from KarachiStock Exchange and Management Association of Pakistan.

Pakistan Cables’ manufacturing facilities and head office are located in Karachi on an 11.5-acre site. It presentlyemploys over 350 people. It has regional office in Lahore and branch offices in Rawalpindi, Multan, Abbottabad,Peshawar and Quetta. The company ’s distribution network covers 35 cities all over Pakistan.

The following types of earth electrodes are recognised forthe purposes of the Regulations:(i) earth rods or pipes(ii) earth tapes or wires(iii) earth plates(iv) underground structural metalwork embedded infoundations(v) welded metal reinforcement of concrete (exceptprestressed concrete) embedded in the earth(vi) lead sheaths and other metal coverings of cables,(vii) other suitable underground metalwork. The type and embedded depth of an earth electrodeshall be such that soil drying and freezing willnot increase its resistance above the required value. The design used, and the construction of, an earthelectrode shall be such as to withstand damage and to take account of possible increase in resistance dueto corrosion. The metalwork of a gas, water or other service shallnot be used as a protective earth electrodes. Thisrequirement does not preclude the bonding of suchmetalwork as required by Regulation

Workmanship and materialsGood workmanship and proper materialsshall be usedGeneralAll equipment shall be constructed,installed and protected and shall becapable of being maintained, inspectedand tested so as to prevent danger so faras is reasonably practicable.All equipment shall be suitable formaximum power demanded by thecurrent-using equipment when it isfunctioning in its intnded manner.All electrical conductor shall be of sufficientsize and current-carrying capacity for thepurposes for which they are intended.All conductors shall either(i) be so insulated and where necessaryfurther effect ively protected, or(ii) be so placed and safeguarded, toprevent danger so far as is reasonably,practicable.Every electrical joint and connection shallbe of proper construction as regardsconductance, insulation, mechanicalstrength and protection.Overcurrent protective devicesWhere necessary to prevent danger, everyinstallation and every circuit thereof shallbe protected against over-current by(i) devices which:will operated automatically at values ofcurrent which are suitably related to the(ii) safe current rating of the circuit, andare of adequate breaking capacity andwhere appropriate, making capacity, and(iii) are suitably located and areccnstructed as to prevent danger fromoverheating, arcing or the scattering ofhot particles when they come intooperation and to permit ready restorationof the supply without danger.Precautions against earth leakageand earth fault curents.Where metalwork of electrical equipment,other than current-carrying conductors,may become charged with electricity insuch a manner as to cause danger:

FUNDAMENTAL REQUIREMENTS FOR SAFETY

(41)

(i) the metalwork shall be connected withearth in such a manner as will causedischarge of electrical energy withoutdanger, or(ii) other equally effective precautionsshall be taken to prevent danger.Every circuit shall be arranged so as toprevent the persistence of dangerousearth leakage currents.Where metalwork is connected with Earthin accordance with relevent regulations.the circuit concerned shall be protectedagainst the persistence of an Earth faultcurrent by:(i) the over-current protective devices asrequired by regulation or(ii) a residual current device or equallyeffective device.The method described in item (ii) aboveshall be used whenever the prospectiveEarth fault current is insufficient to causeprompt operation of the over-currentprotective devices.Where any metalwork of electricalequipment is connected with earth inaccordance with regulation and isaccessible simultaneously with substantialexposed metal parts of other services,the latter shall be effectively connectedto the main earthing terminal of theinstallation.Protective devices and switchesA single-pole fuse switch or circuit-breakershall be inserted in the phase conductoronly.No switch or circuit-breaker, exceptingwhere linked, or fuse shall be inserted inan earthed neutral conductor and anylinked switch or linked circuit-breakerinserted in an earthed neutral conductorshall be arranged to break all the relatedphase conductorIsolation and switchingEffective means, suitably placed for readyoperation, shall be provided so that allvoltage may be cut from every installation,from every circuit thereof and from allequipment, as may be necessary toprevent or remove danger.Every fixed electric motor shall beprovided with an efficient means ofswitching off, readily accessible, easilyoperated and so placed as to preventdanger.

(42)

Accessibility of equipmentEvery piece of equipment which requiresoperation or attention by a person shallbe so installed that adequate space areafforded for such operation or attention.

Precaution in adverse conditionsAll equipment likely to be exposed toweather,corrosive atmosphere or otheradverse condit ions, shall be soconstructed or protected as may benecessary to prevent danger arising fromsuch exposure.All equipment in surroundings susceptibleto risk of fire or explosion shall be soconstructed or protected and such otherspecial precautions shall be taken, asmay be necessary to prevent danger.

Additions and alterations toan installationNo addition or alteration, temporary orpermanent, shall be made to an existinginstallation, unless it has been ascertainedthat the rating and the condition of anyexisting equipment,including that of thesupplier, which will have to carry anyadditional loads is adequate for the alteredcircumstances and the earthingarrangments is a lso adequate.

Inspection and testingOn completion of an installation or anex tens ion o r a l te ra t ion o f aninstallation,appropriate inspection andtests shall be made,to verify so far as isreasonably pract icable that therequirement of regulations have beenmet. The person carrying out theinspection and tests or a person actingon their behalf,shall inform the personordering the work of the recommendationsfor periodic inspection and testing in future.
