Ever wondered what the TEST and RESET buttons on some of your outlets are actually for? You are far from the only one.
Those outlets are GFCIs, and they are designed to cut power almost instantly if electricity starts going somewhere it should not, like through water. That is why they show up in kitchens, bathrooms, garages, and outdoors.
Testing one takes about ten seconds. Plug in a lamp, press TEST, and the lamp should turn off. Press RESET and it comes back on. If nothing happens, or it will not reset, it is time to call an electrician. Once a month is the recommended habit.
Bonus tip: if an outlet in your bathroom or garage stops working, check for a tripped GFCI nearby. One of them often controls several outlets, and a quick press of RESET usually brings everything back.
