What does GFCI stand for?

GFCI stands for Ground Fault Circuit Interrupter. This device is designed to protect people from electric shock by monitoring the current flowing through a circuit. If the GFCI detects an imbalance between the outgoing and incoming current—indicating that some of the current may be flowing through an unintended path, such as through a person—it will quickly cut off the electrical supply, reducing the risk of electrical shock.

The use of GFCIs is particularly important in marine settings where water presence increases the risk of electric shock. GFCIs are typically installed in areas where electrical appliances are used in proximity to water, such as bathrooms, kitchens, and on boats. Understanding the function and significance of GFCIs is critical for ensuring safety in marine environments and complying with regulatory standards.
