GFCI and AFCI Basics

GFCI and AFCI protection have both become fundamental safety devices in electrical systems. Understanding the basics of ground-fault protection for people, and arc-fault protection for 15- and 20-amp branch circuits in dwelling units can ensure that your installations are code-compliant and help you in troubleshooting a circuit. As of the time this article was written (late January 2012), the NFPA code-making panels have met to consider proposals for the 2014 NEC.

Inspecting to the 2008 National Electrical Code

Just like clockwork, the 2008 edition of the National Electrical Code is now available, which always brings a plethora of education and materials on the changes taking place in the NEC. Understanding the changes is important to electrical inspectors in order to understand the safety or enforceability enhancements that have been made to support an electrical installation.

The Truth About AFCIs (Part 2)

AFCIs are not new, but they are newly applied under the NEC rules. A variety of questions have arisen regarding where they must be applied, whether to expect unwanted operation, and how to test and service installations. This part of the two-part article answers some of those questions.

The Truth About AFCIs (Part 1)

Arc-fault circuit interrupters (AFCIs) have just become required for installation in residences under the 2002 National Electrical Code (NEC). Not surprisingly, questions have been raised regarding their application and even the need for them. There have been marketing pitches, technical opinions and, quite frankly, intentional misinformation floating around various industry channels. The intent of this article is to bring out the truth about what AFCIs are and what they are not.

Installing Transient Voltage Surge Suppressors (TVSS)

Surge protection was introduced into the first National Electrical Code (NEC) published in 1897. The primary focus at that time was lightning arresters. In 1981, NEC Article 280 was revised and re-titled "Surge Arresters” in order to align with industry terminology. The title change in the NEC also recognized that surge arresters were being installed where the surge source was other than lightning, such as utility switching, or equipment switching within industrial and commercial facilities.
