Click here to purchase the full version from the ANSI store.(This foreword is not a part of the standard)ForewordIntroductionNational Electrical Installation Standards (NEIS) aredesigned to improve communication among specifiers, purchasers, and suppliers of electrical construction services. They define a minimum baseline ofquality and workmanship for installing electrical products and systems. NEIS are intended to be referencedin contract documents for electrical construction projects. The following language is recommended:Telecommunications bonding and groundingplanning and installations shall be installed inaccordance with NECA/BICSI 607-2011, Standardfor Bonding and Grounding Planning andInstallation Methods for Commercial Buildings.The National Electrical Contractors Association(NECA) asked BICSI , a TelecommunicationsAssociation, together undertook the task of developing this grounding and bonding standard fortelecommunications systems and equipment.NECA-BICSI standards are developed within theTechnical Committees of BICSI and NECA. Membersof the respective committees serve voluntarily andwithout compensation. The companies they represent are not necessarily members of BICSI or NECA.The standards developed by these committees represent a consensus of the broad expertise from withinBICSI and NECA as well as from those outside thathave an expressed interest. The viewpoint expressedat the time this standard was approved was from thecontributors’ experience and the state of the industryat that time. Users are encouraged to confirm thatthey have the latest edition of this standard. NECABICSI reviews its standards, at the minimum, every 5years. At that time standards are reaffirmed, rescinded or revised accordingly. Any suggested revisions tobe included in the next edition should be sent toNECA or BICSI.This standard has been prepared by BICSI/NECAunder the joint jurisdiction of BICSI and NECA andapproved by consensus ballot in accordance with therequirements of the American National StandardsAssociation (ANSI). Use of NEIS is voluntary, andneither NECA nor BICSI assume any obligation orliability to users of this publication. Existence of astandard shall not preclude any member or nonmember of either organization from specifying orusing alternate construction methods permitted byapplicable regulations. This publication is intendedto comply with the edition of the National ElectricalCode (NEC ) in effect at the time of publication.Because they are quality standards, NEIS may exceedthe minimum safety requirements of the NEC. It isthe responsibility of users of this publication to comply with state and local regulations when installingelectrical products and systems.Suggestions for revisions and improvements to thisstandard should be addressed to:NECA Standards & Safety3 Bethesda Metro Center, Suite 1100Bethesda, MD 20814(301) 657-3110 telephone(301) 215-4500 faxPersonnel safety and protection of susceptible electronic equipment from ground faults, lightning,ground potential rise, and electrical surges is of theutmost importance at telecommunications facilities.Cloud to ground lightning discharges must find apath to ground; either discharging directly to theground itself or to structures in contact with ground.v

In eitherevent, proper bonding reduces the harmful effectsassociated with these electrical events.Metallic components for power distribution systemsare bonded together to provide an effective groundfault current path to allow proper operation of overcurrent devices. For telecommunications systems,metallic components are bonded to provide a lowimpedance path for electrical surges and transientvoltages to return to their power source. The earth isalso involved as a path for grounded (earthed) powersystems and for lightning events. Lightning, fault currents, circuit switching (motors starting and stopping), and electrostatic discharge (ESD) are commoncauses of surges and transient voltages. An effectivebonding and grounding system helps to minimizethe damaging effects of electrical surges.Proper bonding and grounding of electrical andinformation transport systems (ITS) infrastructurefacilitates their intended operation. Improperlybonded and grounded electrical systems are a primary cause of power quality issues, which may affectinformation technology (IT) systems operation.Other performance items related to bonding andgrounding for telecommunications within a buildinginvolve power systems, surge protective devices, andelectromagnetic compatibility (EMC). IEEE 11002005 contains recommended practices on these andrelated subjects.designated by the words "should”, "may", or "desirable", which are used interchangeably in this standard.Mandatory criteria generally apply to protection, performance, administration, and compatibility; theyspecify the absolute minimum acceptable requirements. Advisory or desirable criteria are presentedwhen their attainment would enhance the general performance of the cabling system in all its contemplatedapplications. A note in the text, table, or figure is usedfor emphasis or offering informative suggestions.Metric equivalents of U.S. customary unitsThe majority of the metric dimensions in this standard are soft conversions of U.S. customary units(e.g., 100 millimeters [mm] is the soft conversion of4 inches [in]). Wire diameters shown in brackets [ ]are approximate wire diameters (e.g., 6 AWG [(4.1mm (0.16 in)])Life of the standardThis standard is a living document. The criteria contained in this standard are subject to revisions andupdating as warranted by advances in building construction techniques and telecommunications technology.AnnexesAnnex A is informative and not considered a requirement of this standard.PurposeThe purpose of this standard is to allow the designerand installer to enhance their knowledge of effectivetelecommunications bonding and grounding systemsand to strive for installations in a neat and workmanlike manner. The principles and requirements of thisstandard are focused upon the North American region.Specification of criteriaTwo categories of criteria are specified; mandatory andadvisory. The mandatory requirements are designatedby the word "shall": advisory recommendations are viCopyright 2011, National Electrical Contractors Association.All rights reserved.

ScopeThis American National Standard specifies aspects ofplanning and installation of telecommunicationsbonding and grounding systems within a commercialbuilding (see figure 1). This standard is intended toenhance the planning, specification and layout of aneffective telecommunications bonding and groundingsystem. Additionally, this standard specifies installation requirements for components of the telecommunications bonding and grounding system.Figure 1.

BICSI reviews its standards,at the minimum,every 5 years.At that time standards are reaffirmed,rescind-ed or revised accordingly.Any suggested revisions to be included in the next edition should be sent to NECA or BICSI. This standard has been prepared by BICSI/NECA under the joint jurisdiction of BICSI

from electric shock. Bonding and earthing are often confused as the same thing. Sometimes the term Zearth bonding is used and this complicates things further as the earthing and bonding are two separate connections. Bonding is a connection of metallic parts with a Zprotective bonding conductor. Heres an example shown below.
