Document Responsibility: Electrical Systems Designs and AutomationIssue Date: 22 November 2008Next Planned Update: 5 May 20121SAES-P-104Wiring Methods and MaterialsScope1.1This Standard prescribes mandatory requirements for the design and installationof insulated power and control wiring and cable systems. It also prescribesminimum mandatory requirements for outdoor enclosures for electricalequipment and wiring that are not covered by another SAES or SAMSS.1.2For the purpose of this standard, control wiring is wiring used for theinterconnection of electrical control devices, such as pushbuttons,electromechanical relays, meters, transducers, etc., associated with powersystems, and also microprocessor based protection relays for power distributionand motors.1.3For the purpose of this standard, wiring connected on one or both sides toinstruments, distributed control systems, computers, etc., (except for AC powerconnections) is considered instrumentation wiring and is covered by SAES-J-902.SAES-P-104 applies to instrumentation wiring only insofar as it is referenced inSAES-J-902.1.4This standard applies also to the installation of fiber optic cables dedicated to thecontrol of power systems, such as intertrip and switchgear control, that are notpart of a communications system, and to the installation of composite powerfiber optic cables, including composite submarine cables. The use of compositepower-fiber optic cables must be concurred to by the Department responsible forthe maintenance of the fiber optic component of the cable SAES-T-624. Seealso Paragraph 5.14.Commentary Note 1.4:The Department responsible for the maintenance of the fiber optic cables andfiber optic components covered by paragraph 1.4 may impose additionalrequirements related to splicing and terminating the fiber optics, and other.21.5This standard does not apply to internal wiring of manufactured equipmentcovered by SAMSS, or manufactured equipment labeled, listed or certified by atesting agency recognized by Saudi Aramco.1.6This standard does not apply to overhead distributions systems. Refer toSAES-P-107.1.7This document shall not be attached to nor made a part of purchase orders.Conflicts, Deviations and Commentary2.1If there are any conflicts between this Standard and associated purchasing,project or engineering documents, this standard shall take precedence.Page 2 of 35
