GFCIs and Electrocution
“According to Acting Chairman Anne Graham of the U. S. Consumer Product Safety Commission, “The GFCI shock protector constantly monitors electricity flowing through a circuit. If the hair dryer or any electric appliance accidentally topples into the sink or tub, the GFCI will shut down the power in milliseconds to protect the consumer against electrocution [...]

GFCIs – Where are they?
The 2009 Canadian Electrical Code is peppered with references to, and requirements for ground-fault circuit interrupters (GFCIs). For very good reasons, GFCIs have become prevalent throughout many sections of the electrical code. And usually without our knowledge, they have no doubt prevented many injuries and saved many lives. This article provides a summary of these [...]

The Illusion of GFCI Protection
During the required annual pool inspections for commercial indoor pools, the inspector happened upon a ground-fault circuit-interrupter (GFCI) device, with a water cooler connected but without a cover plate. Using his tester it was discovered that the GFCI device protecting the receptacle failed to trip. Expanding the test to all GFCI devices around the pool, [...]

The Inverter
In our top-to-bottom perspective of a PV system, we have arrived at the inverter. The utility-interactive inverter is a key element in the PV system that helps to ensure safe and automatic operation of the system. Peak Power Tracking A PV array is a current source of energy and the output power depends on the [...]

GFCIs and Swimming Pools – A Natural Fit
Most of us have seen or read something about the figure commonly known as the fire triangle (oxygen, heat, and fuel), which is a working model to illustrate and to help one understand the ingredients necessary for most fires. There is another odd triangle that contributes to most electrocutions associated with the swimming pool environment. [...]

ESFI Raises Awareness of New UL and CSA Requirements for GFCIs
To reduce electrically related deaths and injuries through public education, the Electrical Safety Foundation International (ESFI) has joined with the Canadian Standards Association (CSA), Underwriters Laboratories, Inc., the National Electrical Manufacturers Association (NEMA), and the Consumer Product Safety Commission to disseminate information on new requirements for ground-fault circuit interrupters. These new requirements offer a significant [...]
(No Ratings Yet)Test Your Ground Fault Circuit Interrupter
Most homes built since the 1970s have a GFCI in their kitchen and bathrooms. GFCIs appear similar to standard electrical receptacles, but also have “test” and “reset” buttons. An estimated 400 million ground fault circuit interrupters (GFCIs) have been installed across the country. Their built-in test buttons should be used every month and after electrical [...]
(No Ratings Yet)GFCI for Temporary Wiring
Since the original introduction of the Ground-Fault Circuit Interrupters in the 1971 National Electrical Code, these devices have proven to their users and the electrical community that they are worth the added cost during construction or remodeling. Published data shows a decreasing trend in the number of electrocutions in the United States since the introduction [...]
(No Ratings Yet)Check and Be Sure of GFCI Safety Protection
“A safety revolution is underway in the electrical wiring of buildings,” writes Earl Roberts in his book Overcurrents and Undercurrents.1 He is writing about the use of electronics in circuit protection and specifically in the ground-fault circuit interrupter (GFCI). Just as electronics have enhanced the world of consumer appliances and communication, the use of electronics [...]
