GFCI Basics
A GFCI is only as good as its installation and inspection.A ground-fault circuit interrupter (GFCI) is the only protection device designed to protect people against electric shock from an electrical system. Because of this, we need to understand what a GFCI is, how it works, and what its limitations are.We need only to look to the NEC for the definition of a GFCI. The NEC defines it as
Think like a GFCI
With ever increasing locations that need GFCI protection, knowing how to select, install, and test these devices is crucial.Today's ground fault circuit interrupter (GFCI) is the result of a convergence of technology with need. In the late 1960s, over 600 people were electrocuted in the United States using consumer products every year. By 1988, that number had been reduced to fewer than 290 (according

Construction Site Ground-Fault Protection
GFCI protection requires extra attention in a construction environment. The GFCI has no doubt saved many people from electrocution, so it would be easy to start thinking GFCIs will always protect you. By design, they should provide ground-fault protection. But they may not if you don't maintain them and don't test them before use. Consider the following example of poor construction site maintenance
