Homeowners Empowered: Decoding Unlabeled 90s Electrical Panels A recent online tutorial by electrician Sergio Llorente has garnered significant attention for its practical advice on understanding and labeling outdated electrical panels. The video, uploaded on August 29, 2025, addresses a common household challenge: unlabelled circuit breakers in homes built in the 1990s. Llorente meticulously explains the function of each component, from the Interrupter General Automatic (IGA) which manages total installed power, to the differential switch designed to protect individuals from electrical leaks. He then details the various Individual Automatic Protectors (PIAs) responsible for specific circuits such as ceramic hobs, ovens, washing machines, dishwashers, water heaters, and general lighting and power outlets. "In the 90s, these panels weren't labeled," Llorente states in the video, "only the technician knew what each one corresponded to." He also points out a lesser-known detail of 90s wiring, where general power outlets were often connected to the lighting circuit. The tutorial aims to equip homeowners with the knowledge to properly label their panels, preventing inconvenience and potential losses, such as food spoilage during power outages. Llorente offers a downloadable PDF template to assist viewers in organizing their home's electrical system. The video's popularity underscores a widespread need for accessible information on home electrical safety and maintenance.
