Ground Fault Circuit Interrupter
Safety first! Know the location of all safety breakers, fuses and switches and how to reset them. Any new additions, repairs, upgrades or replacements to any electrical service should be done by a certified tradesperson. Electricity may injure/kill the unwary.
A Ground Fault Circuit Interrupter (GFCI) is a safety device that prevents a surge in abnormal levels of electrical current flowing through it. When properly installed and regularly tested the GFCI will immediately disconnect hazardous current flows from whatever appliances are connected to it. The human threshold for pain will say ouch very quickly yet the GFCI says ouch far faster.
There are two types. The breaker type is installed directly in the service panel and is distinguished by a coloured test button. The other is designed to be installed in the outlet itself. They both must be tested monthly to ensure their usability as indicated by the silver decal supplied by the manufacturer and added to either the breaker or at the outlet. They are typically installed in kitchens, bathrooms, garages, workshops and the exterior of homes. Others include heating pads, waterbeds and electric blankets. Replace non-functioning or faulty G.F.C.I. receptacle than trying to repair them.
To test the GFCI, first plug in an appliance that will not be adversely affected by the testing process, such as a hair dryer. Upon pressing the test button the GFCI is supposed to cut the power off to the appliance. Push in the reset button. If the GFCI does not cut off the power then you must regard the GFCI faulty and have it serviced by a professional. GFCIs become more prone to disfunction after one or two years for not being tested. We suggest that the freezer and fridge not be plugged into GFCIs. Typical areas for their use include kitchens, bathrooms, waterbeds, garages, exterior walls, upgraded knob and tube and workshops.
We recommend a qualified electrician do all tasks, as they offer quality materials, proper installation requirements and a written guarantee.
Know that, for peace of mind, the care and attention you give your home will serve you well year after year and in comfort.
