How GFCIs Empower Panel Builders to Protect Against Electrical Shock and Save Lives

With power, comes great responsibility. A panel builder who can effectively integrate ground-fault circuit interrupters (GFCIs) into a system can make the difference between life and death. Ground-fault circuit protection is one of the most effective preventative measures against electrical shock because it actively reacts to irregular electrical conditions, regardless of a worker’s qualifications or use of personal protective equipment (PPE).
