This Committee R~eport is essentially the Recommended Prac- tice for ElectricM Equ!pment Maintenance; NFPA No. 70B-T, which is proposed for tentative adoption. The document has been submitted to letter ballot of the Committee which consists of 26 voting members and two alternates. Final comments and sug- gestions were invited. Of the 26 voting members, 25 have voted affrmatively. There were no negative ballots. Mr. Schaad did not return his ballot. 52 EEM-2 EXPLANATION OF REPORT Since this Committee reports to the Association through the ArationM Electrical Code Correlating Committee, this report was also submitted to them for letter ballot. Over a period of many years, the need for guidance to promote the safety of persons and property through effective electrical equip. ment maintenance has been increasingly evident. In the fall of 1967 the Board of Directors of the National Fire Protection Av soeiation authorized the formation of an Ad Hoe Committee on Electrical Equipment Maintenance to determine the need for the development of a suitable document on this subject. In reaching its affirmative decision early in 1968, the Ad Hoe Committee pointed out many reasons why it believed the National Electrical Code waa not the proper document in which to cover the maintenance of electrical equipment. However, the high frequency of electrical accidents attributed to lack of maintenance, which results annually in numerous fatalities and serious injury as well as high monetary losses of property, caused the Committee to advise that it was a subject requiring prompt attention. In June 1968 the Board of Directors authorized the formation of a new NFPA Committee on Electrical Equipment Maintenance having the following scope: "To develop suitable texts relating to preventive maintenance of electrical systems and equipment used in industrial-type appli. cations with the view of reducing loss of life and property. The purpose is to correlate generally applicable procedures for pre. ventive maintenance that have broad application to the more common classes of industrial electrical systems and equipment without duplicating or superseding instructions which manufae. turers normally provide. Reports to the Association through the Correlating Committee of the National Electrical Code Com- mittee." With this background the Committee was organized in De- cember 1968. Its large and very active membership has seen few changes in personnel since its inception. It should be pointed out that the members are individually highly qualified and collectively the committee representation includes equipment manufacturers; installers; inspectors; safety, labor, and insurance organizations; users of the equipment; maintenance contractors and engineers; representatives of the National Electrical Code Committee and other NFPA Committees; and specialists. All committee members have made a fine contribution to this endeavor. 53 ELECTRICAL EQUIPMENT MAINTENANCE Recommended Practice for ELECTRICAL EQUIPMENT MAINTENANCE NFPA No. 70B.T, 1973 HISTORY The Board of Directors of the National Fire Protection Association in the fall of 1967 authorized the formation of an Ad Hoc Commit° tee on Electrical Equipment Maintenance to determine the need for the development of a suitable document on this subject. The purpose of the document would be to give recommendations on the maintenance of various types of electrical installations, ap- paratus, and equipment usually found in industrial and large com- mercial type installations. Various highly diversified interests and organizations were invited to participate. At a meeting of the Ad Hoc Committee held January 10, 1968, in New York, with 31 representatives attending, it was pointed out that several requests had been made to the National Electrical Code Committee to include maintenance recommendations in the NEC. The subject had been discussed by the Correlating Com- mittee of the National Electrical Code Committee and the de- cision was made that the Code was not the proper document in which to cover the maintenance of electrical equipment. 1LIow- ever, the high frequency of electrical accidents attributed to lack of maintenance, which result annually in numerous fatalities and serious injuries as well as high monetary losses of property, caused the committee to recognize that it was a subject requiring attention. It was noted that electrical safety information breaks down logically into four main subdivisions: (1) design or product stand- ards; (2) installation standards (as covered by the National Elec- trical Code and the National Electrical Safety Code; (3) mainte- nance recommendations; and (4) use instructions. The problem was to explore whether something more should be done in the interest of electrical safety on the maintenance of electrical equip- ment and what form activity in this field should take. It was recognized that much has been done to enunciate mainte- nance needs for specific types of equipment by the equipment manufacturers, and that guidance is available on the general subject from a number of sources. However, it was also felt de- sirable to bring together some of the general guidelines in a single document under the NFPA procedure. The stature of the docu- ment would also be enhanced if it could in some way become as- sociated with the National Electrical Code. To this end, a tenta- 54 HISTORY 70B--3 tire scope was drafted for presentation to the Board of Directors of the National Fire Protection Association with a recommenda. tion that an NFPA Committee on Electrical Equipment Mainte. nance be authorized. On June 27, 1968 the NFPA Board of Directors authorized the establishment of an NFPA Committee on Electrical Equipment Maintenance with the scope statement indicated below (which was subsequently amended to include the last sentence): "To de. velop suitable texts relating to preventive maintenance of elec. tdcal systems and equipment used in industrial-type applications with the view of reducing loss of life and property. The purpose is to correlate generally applicable procedures for preventive mainte. nance that have broad application to the more common classes of industrial electrical systems and equipment without duplicating or superseding instructions which manufacturers normally provide. Reports to the Association through the Correlating Committee of the National Electrical Code Committee." The committee was formed and an organizational meeting was held December 12, 1968 in Boston. Twenty-nine members or representatives attended. This Recommended Practice on Elec. trical Equipment Maintenance represents the cumulative effort of the entire Committee. 55 70B-4 ELECTRICAL EQUIPMENT MAINTENANCE TABLE OF CONTENTS Page No. Chapter 1 General 110.

Introduction The Distribution Board, refers to an equipment which consists of bus bars, and possible switches, fuse links and Automatic protective equipment, bypass equipment, for connecting, controlling and protecting a number of branch circuits fed from one main circuit of a wiring installation in a building or premises for easy and safe handling of incoming power supply. These are, also used to protect the electrical distribution system in turn, connected electrical equipment from being damaged due to various faults like short circuit, over load, earth leakage, etc. The Conductor system by means of which electrical energy is conveyed from bulk power source or sources to the consumers is known as distribution system, which may be divided into two systems known as high voltage (primary) distribution and low voltage (secondary distribution). From generating stations the Electrical Power is usually transmitted to various Sub- stations, through extra high tension transmission lines at voltages from 33 to 220 kV and at these Sub-stations this voltage is stepped down to 11 or 6.6 or 3.3 kV and power at this voltage is conveyed to different sub-stations for distribution and to the bulk supply consumer.
