Yes. You should always turn off the power to the work area before beginning, use a voltage tester to ensure it’s off, and wear protective gear, such as insulated gloves or safety glasses, to prevent risk of injury. Proper wiring and grounding techniques are also necessary to make sure the job is done right the first time and won’t harm any future homeowners. 

Outlets do wear out, usually within 15-25 years, but they can fail even sooner than that —sometimes in a matter of years. If your plugs always slide out after you put them in, this is a sign your outlets need to be replaced. Additionally, if your outlets are damaged, cracked, discolored, or regularly tripping the circuit breaker, they may be at the end of their life.

According to the National Electrical Code (NEC), GFCI outlets should be installed in wet or damp locations where they might be splashed with water or other liquids. This is to protect against ground faults, which are more common around water. Specific areas that require GFCI outlets include kitchens (especially near counters), bathrooms, laundry rooms, basements, garages, and all outdoor receptacles. Depending on local electrical codes, you may need at least one GFCI outlet in these rooms, or every outlet in the area may need to be GFCI protected.

Wiring can last anywhere from 50 to 70 years, but all kinds of mishaps can occur that reduce the lifespan of your electrical wiring, including severe weather conditions, pests, and even faulty wiring. Keeping a preventative maintenance scheduling and hiring an electrician for an annual electrical inspection will keep your wiring system around for as long as possible.
