NCCER Residential Wiring Practice Exam

The required type of outlet in kitchens, bathrooms, and outdoor areas is a Ground Fault Circuit Interrupter (GFCI) outlet. These outlets are specifically designed to protect individuals from electric shock by monitoring the electrical current flowing through the circuit. If the GFCI detects an imbalance between the incoming and outgoing current, it immediately shuts off the power to the outlet. This is particularly important in areas where water is present, such as kitchens and bathrooms, because water and electricity can create hazardous situations.

For outdoor areas, the likelihood of encountering moisture increases due to weather conditions, making GFCIs essential to enhance safety. The National Electrical Code (NEC) mandates the use of GFCI protection in these specific locations, underscoring the importance of safety in residential wiring. This requirement helps to prevent serious injuries and fatalities caused by electric shock, which can occur if a fault condition arises in wet or damp locations.
