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.

  • “Electrical Safety in the Workplace”
    “Electrical Safety in the Workplace” This material was produced under Grant #SH-16609-07-60-F-26 from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or policies of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government. September 2008 “Electrical Safety in the Workplace” Course Goal – The aim of this program is to provide comprehensive on-site training to high-risk workers (i.e. skilled trades and maintenance workers) and management on the requirements of Sub Part S, and the prevention of serious injuries from electrical hazards at their worksites. Participants will develop understanding of the requirements of OSHA Sub Part “S” and NFPA, 70E and will be able to identify and reduce or eliminate electrical safety hazards in their workplace. Electrical Safe Work Practices including electrical safety principles, guidelines for qualification of personnel, job planning requirements and Management and Personal Responsibility will be covered. Section Content Objective 1 Introduction to Participants will be able to: Electrical Safety • Explain the issues (statistics) associated with poor electrical safety in the workplace. • Recall key electrical terms which are essential to understanding and meeting the requirements of key electrical safety standards; i.e. OSHA 29 CFR 1910.331-.335, NFPA 70E, NEC (NFPA 70) • Define and differentiate between qualified and unqualified persons under OSHA Sub Part S. and the training requirements for each. • Describe the intent of an Electrical Safety Program and list the essential elements of an effective program.
