Arc Fault/Ground Fault Tester Can Take the Heat
Arc Fault/Ground Fault Tester Can Take the Heat The 2002 NEC implemented new requirements to help reduce the number of electrical fires caused by parallel arc faults in branch circuit wiring. All branch circuits supplying bedrooms in single-family and multi-family bedrooms must now be protected by an arc fault circuit interrupter (AFCI). More electricians are installing AFCIs to comply with the Code,

The National Electrical Code (NEC) requirements for arc fault circuit interrupters
The National Electrical Code (NEC) requirements for arc fault circuit interrupters (AFCIs) have become more stringent with each passing Code cycle, stirring up much discussion and debate among builders, electrical contractors, and other professionals involved in home construction. While these devices were previously only required to protect the bedroom, the 2008 NEC now requires the technology to

The Basics of Arc-Fault Protection
Although new to the NEC, AFCIs are important for protecting against arc faults. Unsafe arc faults can occur as series or parallel arcs. A series arc can occur when the conductor in series with the load breaks. The series configuration means the arc current cannot be greater than the load current the conductor serves. Typically, series arcs don't develop sufficient thermal energy to create a fire.
Applying and Using Arc-Fault Circuit Interrupters
According to the National Fire Protection Association and the National Fire Incident Reporting System data, the five-year period from 1994 to 1998 averaged 73,500 annual electrical fires that were responsible for 591 deaths, 2,247 injuries, and property damage totaling $1,047,900,000. A report by the National Association of State Fire Marshals (NASFM) states that of these 73,500 electrical fires,
Combination AFCI First Product of Its Kind on the Market

Handheld circuit tester The redesigned SureTest branch circuit analyzer is compatible with the latest generation of arc fault circuit interrupters (AFCIs) and now features a super-bright OLED display and enhanced measurement accuracy. The tester plugs into any 120V receptacle and will check for verification of AFCI protection, proper operation of installed GFCIs, the presence of a shared neutral,
AFCIs Primed to Branch Out
Much like the debates that arose with the introduction of the ground fault circuit interrupter (GFCI) in the early '70s, the arc fault circuit interrupter (AFCI) has followed a similar fiery path in recent years. Some engineers and industry consultants have challenged the merits of the technology. Installers have balked at the high unit price per device. Technicians have fretted over test methods
AFCI Article Sparks Reader Debate
Your magazine is very informative. I would like to comment on the article by Gerald Winstanley from NEMA, starting on page C34 of the November 2007 issue. The article on arc fault detectors talks about the increased cost of using these breakers. The only increased cost the author cites is arc fault breakers vs. regular breakers. It seems he forgot that when you install these AFCI breakers you can
AFCI test instrument may not be safe, says UL
Electricians using an arc fault circuit interrupter (AFCI) circuit tester manufactured by Etcon may not be getting the shock protection they were expecting. Underwriters Laboratories (UL) is notifying consumers who have purchased the AF120 model AFCI test instrument hasn’t been evaluated by the UL and bears an unauthorized UL listing mark. In addition to the potential shock hazard, the receptacle
Addressing Arc Flash Concerns Through Smart Design
Every so often, the electrical industry is able to add to our understanding of what makes a safe, well-designed electrical system. This knowledge can have a profound effect on the way we design, maintain, and operate electrical systems. Such is the case with the growing understanding of the arc flash hazards faced by the workers who operate and maintain these systems. As electrical engineers and designers,
