From the Manufacturer The primary cause of shock and electrocution in the home is an electrical condition known as Ground Fault. The problem is so extensive that the National Electrical Code mandates the use of Ground Fault Circuit Interrupters for all bathroom, kitchen, basement and garage outlets in all new homes in the US. Even so, over 170 million Americans live in homes built before this mandate was put in effect, and are hence vulnerable to shock or electrocution from ground faults. The Portable GFCI Tri-Cord has built-in electronic circuitry which monitors electrical current and shuts off power in just 25/1000?s of a second if a ground fault is present. Indoors, it is perfect for use in the basement, garage or workshop.
