What kind of system is GFCI designed to protect?

GFCI, or Ground Fault Circuit Interrupter, is specifically designed to protect electrical systems related to water. This protection is critical because water and electricity can create dangerous situations that may lead to electric shock or electrocution. GFCIs continuously monitor the flow of electricity in a circuit and will shut off the power if they detect any imbalance, which indicates a potential ground fault – a situation that often occurs when water comes into contact with electrical outlets or devices.

It is essential to have GFCIs in areas where electrical systems may come into contact with water, such as in swimming pools, bathrooms, kitchens, or outdoor installations. The goal is to increase safety and reduce the risk of electrical accidents that can have serious consequences.

Other systems, like heating, water filtration, or ventilation, may have their own safety mechanisms but are not specifically protected by GFCI devices in the same way that electrical systems interacting with water are.
