Why is GFCI important?
GFCIs “sense” the amount of electricity flowing in the circuit from even small amounts of milliamps, hence the GFCI reacts quickly if it is necessary to shut off the circuit. Its main purpose is protecting workers from electrical shocks; GFCIs are usually used on construction sites, wet locations and other high-risk worksites. While GFCI does not protect workers from touching two “hot” wires contact hazards, it will protect against ground-fault, which is the most common form of electrical shocks, as well as the destruction of wire insulation, fires and overheating.
Types of GFCIs
There are three main types of GFCIs available to assist in proper electrical hazard prevention.
It is important to remember that GFCIs are to be installed in worksites where objects can conduct electricity easily, such as a close proximity to water. Testing must be done on a minimum of a monthly basis as GFCI devices can damage and wear out. This can be done by simply pressing the “Test” then the “Reset” buttons, be sure to consult the instructions before attempting this for the first time. If the GFCI circuit fails to work, a qualified electrician must replace it as soon as possible.
GFCIs alone will not guarantee the safety of your workers, proper safety training is crucial in maintaining an injury-free workplace. Following OSHA regulations on electrical safety in your workplace is a great way of starting this process.
