ABSTRACT
Modern power distribution systems have evolved over decades and are now relatively safe, reliable, and easy to use, provided they are used with caution by qualified personnel who understand how to use them properly. Our safety record regarding electrical accidents in the industry is relatively good, although even one accident is too many. Because the electrical distribution systems we use are capable of delivering massive quantities of current, we should understand not only their components, but also how to assemble them according to the best practices and safety requirements and regulations.
