9.7 Maintenance-Related Design Study.

9.7.1

A maintenance-related design study uses the risk assessment study as input and evaluates designconcepts for electrical equipment and installations that impact the safety of maintenance practices. Theobjective is to develop design options that eliminate or reduce hazards or reduce risk. Facilitiesmanagement can use this study to assist in making decisions on implementing changes to the electricalequipment.

9.7.2

After the risk assessment study in Section 9.6 is completed, a maintenance-related design studyshould be performed.

9.7.3

For more information, see the safety-related design requirements in Informative Annex O ofNFPA 70E .

though the material added is useful in general, its another item that is not really a task for the target audience ofthe document, the electrical maintenance person. we should be prudent not to expand on this in future revisions.

Crnko, Timothy

Task Group of A. Corbett, W. Harris, J. White, and T.Crnko expanded 9.7 to be considered in the 2nd DraftMeeting as follows: 9.7 Maintenance Related Design Study 9.7.1 A maintenance related design study shoulddevelop design options that eliminate or reduce hazards or reduce risk for daily or maintenance operations. Thisstudy should use input that may include the electrical system design, equipment maintenance instructions, thecompany’s historical maintenance data, as well as results of other studies such as the reliability and the riskassessment studies. The study should evaluate design and operational concepts for electrical equipment andinstallations which impact the safety of maintenance practices and then makes recommendations forimprovement. Facilities management should use this study to make decisions for implementing. Designconsiderations to enhance operations should include the entire life cycle cost of the building or system. The initialcost for efficient use of energy and to provide an efficient maintenance environment should be considered asvaluable long term investments that support daily operations. Workspaces and systems should be designed toallow safe maintenance or urgent repair while other operations continue. System monitoring equipment can beused for planning predictive maintenance and help prevent unplanned outages. 9.7.2 A maintenance relateddesign study should include evaluating various options such as maintenance-related design elements are allowingsufficient clearances to remove and install drawout circuit breakers, installation of remote operating controls andremote racking for circuit breakers, installation of lift mechanisms to allow safe removal of drawout circuitbreakers, installation of motor control centers with the capabilities for individual buckets to be racked in or outremotely, installation of permanently-mounted absence-of-voltage testers, performing an incident energy analysis

in addition to short circuit and coordination studies, designing redundancy into the electrical power system tofacilitate safe maintenance work practices, installation of motor overload relays so they can be reset withoutexposing the worker to energized conductors or circuit parts, installation of infrared windows to allow for testingand inspection without exposing workers to energized parts, thermal sensors for critical terminations, ultrasonicsensors in medium voltage equipment, partial discharge monitoring of critical cables and equipment, andinstallation of automatic transfer switches with maintenance by-pass switches. 9.7.3 After the risk assessmentstudy in 9.6 is complete, NFPA 70E Informative Annex O Safety-Related Design Requirements should bereferenced for other items to consider for evaluating in the maintenance related design study.

First Revision No. 4-NFPA 70B-2017 [ Section No. 11.4 ]

11.4 Frequency of Tests.

Most routine testing can best be performed concurrently with routine preventive maintenance, because asingle outage will serve to allow both procedures. For that reason, the frequency of testing generallycoincides with the frequency of maintenance. The optimum cycle depends on the use to which theequipment is put and the operating and environmental conditions of the equipment. many factors such asequipment design, condition, use, age, loading, and duty cycle as well as prior recorded maintenancedata, environmental factors, and reliability requirements. In general, this cycle can range from 6 monthsto 3 years, depending on conditions and equipment use. from 3 months to 6 years. The difficulty ofobtaining an outage should never be a factor in determining the frequency of testing and maintenance.Equipment for which an outage is difficult to obtain is usually the equipment that is most vital in theoperation of the electrical system. Consequently, a failure of this equipment would most likely create themost problems relative to the continued successful operation of the system. In addition to routine testing,tests should be performed any time equipment has been subjected to conditions that possibly could havecaused it to be unable to continue to perform its design function properly. Annex L provides an initialguideline for equipment maintenance intervals. See Section L.1 .

L.1 Introduction.


22 of 28 5/10/17, 2:28 PM

This annex provides, in Table L.1, an initial guideline for maintenance intervals for equipment. It should bestressed that environmental or operating conditions of a specific installation should be considered andmight dictate a different frequency of maintenance than suggested in this annex (see 8.2.4). Chapter 12and Annex K deal specifically with the maintenance of equipment that, by nature of its application,necessitates long intervals between shutdowns. It should be noted that maintenance, inspection, and testmethods for equipment that can operate for long periods are essentially the same as for equipment thatmight be shut down frequently. However, the recommended work should be performed with more care anddiligence to obtain the desired reliability for service to loads that can operate continuously for months oryears.
