NORTHBROOK, Ill., - February 6, 2006 - To reduce electrically related deaths and injuries through public education, Underwriters Laboratories Inc. (UL) has joined with the Electrical Safety Foundation International (ESFI), the Canadian Standards Association (CSA), the National Electrical Manufacturers Association (NEMA), and the Consumer Product Safety Commission (CPSC) to disseminate information on new requirements for ground fault circuit interrupters (GFCIs). These new requirements offer a significant safety improvement for consumers.
The new requirements are being set by UL and the CSA and apply to the harmonized standard, UL 943, Safety Standard for Ground Fault Circuit Interrupters (GFCIs) and CSA C22.2 No. 144.1 (Ground Fault Circuit Interrupters).
Since the early 1970s, GFCIs have reduced household electrocutions by protecting residents from lethal currents. A GFCI is a wiring device that de-energizes a circuit when a current to ground could result in electric shock. The GFCI "interrupts" power before it reaches a level that would cause injury. The National Electrical Code® (NEC) requires GFCIs to be used in bathrooms, kitchens, garages, basements, crawlspaces, and outdoors. Similarly, the Canadian Electrical Code (CEC) requires GFCIs to be used in many locations such as bathrooms, outdoors, basic care areas of hospitals, pools, spas, and hot tubs.
Before the introduction of GFCIs, more than 700 people died from household electrocutions each year. As of 2001, that number had been reduced to 400 cases annually. A 2001 field study from UL and the National Electrical Manufacturers Association, however, determined that a small but significant percent of GFCIs, particularly older ones, did not work after several years. This created a demand for more stringent safety features that can alert users when a GFCI malfunctions.
The new UL and CSA requirements include:
- End of Life Provision: when a GFCI receptacle is incapable of passing its internal test function (it can no longer provide ground fault protection) it will either a) render itself incapable of delivering power, or b) indicate by visual or audible means that the device must be replaced.
- Reverse Line-Load Miswire: a GFCI will deny power to the receptacle face if it is miswired.
In the United States, manufacturers must stop producing old versions of GFCIs on July 28, 2006, and must introduce new, redesigned GFCIs after that date. Distributors can sell and contractors can install old GFCIs until their supplies run out. The UL revisions will not affect the NEC, which regulates installations, not products.

The older style GFCI’s are no longer available and have been replaced by the Leviton Smart Lock Pro series # 7599. As you may expect, this newer product has a higher price point since there are more electronics involved. We currently stock the 7599 in white, almond, ivory, black and gray.
