How many types of GFCIs are available?

Ground Fault Circuit Interrupters (GFCIs) are essential safety devices designed to protect against electrical shock. There are three main types of GFCIs commonly found in residential and commercial settings:

1. Receptacle GFCIs: These are standard electrical outlets with integrated GFCI protection. They can replace ordinary outlets in areas where water is present, such as kitchens, bathrooms, and outdoor locations.

2. Inline or Wiring GFCIs: Installed in the electrical panel or junction boxes, these devices protect an entire circuit. They are often used when multiple outlets are installed in wet locations, ensuring that all connected devices receive ground fault protection.

3. Portable GFCIs: These are plug-in devices that provide ground fault protection for temporary setups, such as construction sites or outdoor activities. They can be used with any standard plug to ensure safety when using electrical tools or appliances in potentially wet conditions.

Understanding these three types is crucial for ensuring proper safety measures are in place when working with electrical systems, particularly in environments where water and electricity may interact.
