What does G.F.I. stand for in electrical safety?

G.F.I. stands for Ground Fault Interrupter, which is a crucial safety device used in electrical systems to prevent electric shock. It monitors the current flowing through the circuit and compares it to the current returning. If there is an imbalance, indicating that some of the current is leaking through an unintended path (such as through a person's body), the G.F.I. quickly interrupts the circuit by shutting off the electricity. This rapid response helps to protect individuals from serious injuries or fatalities due to electric shock.

Understanding the importance of G.F.I.s is essential in environments where moisture is present, such as bathrooms, kitchens, and outdoor areas, where the risk of electric shock increases. Their use is mandated by electrical codes in many jurisdictions to enhance safety in residential and commercial installations.
