According to the U.S. Consumer Product Safety Commission (CPSC), residential electrical equipment is involved in approximately 150,000 fires each year in the United States, which result in 850 deaths, 6,000 injuries, and more than $1.5 billion in property losses. A new technology called “arc-fault detection” has been developed to reduce this problem. Research conducted by [...]

Overcurrent protection for electrical equipment can be accomplished by several different methods. The general rules for overcurrent protection of conductors and equipment are found in Article 240 of the National Electric Code. Section 240-2 indicates Article 440 shall be used for protection of air-conditioning and refrigerating equipment. In Part C of Article 440, specifically Section [...]

When we talk about mini- mum ground clearances of span conductors, we have to know the sag of the conductor because the minimum height of attachment on a structure to comply with the National Electrical Safety Code® (NESC®) is the minimum clearance plus the maximum sag of the conductor. The ground clearance for equipment cases [...]
(No Ratings Yet)What should happen when the electrical utility or a utility customer decides to convert the ungrounded 600 volt, 3-wire supply to a 600/347 volt, 4-wire, solidly grounded electrical supply? Some commercial and industrial businesses still prefer to use an ungrounded 600 volt supply for service continuity reasons, or to avoid the costs of converting to [...]
(No Ratings Yet)Over 4700 proposals were submitted to the National Fire Protection Association to amend the 1999 National Electrical Code. The 20 NEC Code-Making Panels met in January 2000, and took action on proposed changes to articles of the Code within the scope of each respective panel. Listed below is the first of a two-part brief summary [...]
