With any hazard there is a definable risk and a definable impact and it is no different for the arc-flash hazard. Quite often the impact in business interruption far outweighs the physical damage to equipment and industry statistics would suggest that the average physical equipment damage is around $50,000 and the business interruption cost around [...]

Although arc hazards have existed since man began using electricity, increasing deaths, injuries and property loss from arcing faults have led to increased awareness of the issue and investigation into methods of protection. According to statistics compiled by CapSchell Inc, a Chicago-based research and consulting firm that specializes in preventing workplace injuries and deaths, there [...]

Five to ten times per day, an electrical arc-flash accident occurs that seriously injures or kills someone in the United States. Standards such as NFPA 70E and electrically safe work practices are now in place to reduce these accident statistics, and OSHA enforces these published safety standards. Electrical accidents are devastating to the affected workers [...]

Arc-fault circuit interrupters (AFCIs) have become a familiar technology to electrical contractors during the past decade. The first branch-feeder AFCIs debuted in the late 1990s, and detected exclusively parallel arcs, or current that travels from one circuit conductor to another. They were followed more recently by combination AFCIs, which respond to both parallel and series [...]

Smoke alarms, fire extinguishers, emergency escape ladders—these are all proven methods for making a quick and safe escape from a fire in the home. However, in addition to these measures, proven technology exists to prevent fires from starting in the first place. Arc-fault circuit interrupters (AFCIs)— the next generation in circuit breaker technology—are one such life-saving tool that should be considered by home owners and home builders alike.

Electrical arc-flash and shock hazards have been recognized as particularly dangerous and fairly frequent occurrences that put the lives and health of electrical workers at significant risk. Statistics indicate that five to ten arc-flash accidents that involve a fatality or serious injury to an employee occur every day in the United States. Those incidents most [...]
(No Ratings Yet)The electrical industry has always had a fascination with testers. There are testers for GFCIs, voltage drop, circuit polarity, circuit continuity and now the latest addition—the arc-fault circuit interrupter (AFCI) tester. NEC 210.12 requires AFCIs on 15- and 20-ampere branch circuits that supply bedrooms in dwelling units. The intent of the AFCI is to detect [...]

Did you know that residential electrical fires, as reported by the National Fire Protection Association, causes an average of nearly 73,000 fires every year? These fires are responsible for 591 deaths, 1400 injuries and over $1 billion in property losses. Eighty-three percent of these electrical fires are caused by electrical arcing. Can something be done [...]

During 2003, many AFCI articles and comments have appeared in IAEI News. This publication activity is associated with the actions taken by code-making panel 2 on the more than 60 proposals received relative to Section 210.12 of the NEC. In particular, CMP-2 has proposed a revision that would require protection by a combination AFCI. This [...]
(No Ratings Yet)by Clive Kimblin, Eaton Cutler-Hammer It is true that code-making panel 2 has proposed revising 210.12(B) to require “an arc-fault circuit interrupter, combination type, installed to provide protection of the branch circuit.” However, we believe, that it is not true that a change to the existing Code is advisable. The need and benefit has not [...]
