IEEE 576-2000 pdf download IEEE Recommended Practice for Installation, Termination, and Testing of Insulated Power Cable as Used in Industrial and Commercial Applications
1.Overview
1.1 Scope
This recommended practice provides a guide for installing, splicing, terminating, and feld prooftesting of cable systems in industrial and commercial applications. It is not intended to be a designdocument, although many of the problems of installation can be avoided by designing cable layoutswithin the installation limits of this recommended practice.
1.2 Purpose
The purpose of this recommended practice is to provide a uniform guide of installation limits that willavoid premature cable failure due to improper installation and mechanical damage during installation.It is intended to provide a reference that can be specified for cable installations.
2.References
This recommended practice should be used in conjunction with the following publications:Accredited Standards Committee C2-1997, National Electrical Safety Codee (NESC

3. Definitions
3.1 electrical connection: The point at which two or more electrical conductors are joined together toestablish electrical continuity.
3.2 jamming: The wedging of cables in a conduit when three cables lie side by side in a flat plane.
3.3 minimum bending radius: The minimum radius to which an insulated cable can be permanentlybent that will not result in mechanical damage to the cable. In a bend, the radius is measured to theinside curve of the cable, not to the centerline of the cable.
3.4 sidewall pressure: The pressure exerted on an insulated cable as the result of the cable’s beingpulled around a bend during installation.
3.5 weight: In non-technical work and often in engineering, weight is commonly used as a synonymfor mass. In this document, however, it is used as in physics, to refer to the apparent force of gravityon a object. Like other force quantities, it is expressed in newtons in the International System (SIand in pounds-force in the inch-pound system.
3.6 weight correction factor: A dimensionless factor (> 1) by which cable tensions and sidewallpressure are adjusted due to different cable arrangements, when cable is pulled around bends or inconduit. For example, for three cables in a triangular configuration in conduit, the top cable does nottouch the conduit, but its weight will cause increased tensions and sidewall pressures for the othertwo cables.
4. Pulling tensions
4.1 Maximum pulling tension on cable
4.1.1 Pulling eye attachment
With puling eye attached to copper conductors, the maximum pulling tension should not exceed0.008 times circular-mil area (Cm). With pulling eye attached to aluminum conductors, the maximumpulling tension should not exceed 0.006 times circular-mil area (Cm ).
