Which one of these is a common application for GFCI protection?

GFCI (Ground Fault Circuit Interrupter) protection is essential in areas where electrical devices may come into contact with water, as it helps prevent electric shock by cutting off the current when it detects an imbalance between incoming and outgoing currents. The common application of GFCI protection for receptacles used with outdoor tools is crucial because these tools often operate in wet or damp conditions, such as gardens or yards where rainwater may be present.

Using GFCI protection for outdoor tools enhances safety by reducing the risk of electrocution while using equipment like lawnmowers, trimmers, or other power tools outside. It ensures that if a fault occurs, the power is interrupted almost instantly, thereby protecting the user from serious injury.

While receptacles in laundry rooms and grounded extension cords used indoors may also be areas where GFCI protection is advisable, outdoor tools specifically face a higher risk of water exposure, making them a prime application for GFCI technology. Wiring for ceiling lights, on the other hand, is less likely to require GFCI protection unless the lights are installed in a location prone to moisture, rendering them a less common application for GFCIs compared to outdoor tools.
