What is the function of a hospital GFCI?

The function of a hospital Ground Fault Circuit Interrupter (GFCI) is to enhance safety by continuously monitoring the electrical current flowing through the hot and neutral conductors. If it detects a significant difference in the currents—indicating that there is a leakage of current, which could signify a fault—such as when electricity is flowing through a person instead of returning through the neutral wire, the GFCI promptly disconnects power to prevent electric shock. This capability is crucial in a hospital setting where patients may be connected to various electrical devices, making it essential to protect them from potentially life-threatening electrical faults.

In this context, the ability to compare the currents and react in real time significantly reduces the risk of electrocution, which is why this function is a vital aspect of patient safety and standard electrical protection protocols in healthcare environments.
