Installing a GFCI Switch
The GFCI (ground fault circuit interrupter) is the switch located where an outlet might come into contact with moisture. You probably have them in your bathrooms, kitchen and laundry room. One of the problems with this home improvement is that many of the GFCi switches have been redesigned or reformatted so the online how-to videos you find may not suit your switch.
“The GFCI switch is very important for safety and electric shock hazard, so installation should always be done by a professional,” says Daniel Ives. While some new lights on the patio would make it more enjoyable, it’s common to hook up the wiring on the wrong side or install it so that the outlet works but not the essential safety features.
“And as with all electrical repairs, there is always a risk of shock for those doing the installation, but that risk significantly increases if you’re not a licensed professional who knows what they’re doing,” says Ives.
