Signs that your home's electrical system may require an upgrade include frequent breaker trips, flickering lights, burning smells from outlets, and the use of multiple extension cords due to insufficient outlets. These symptoms suggest that your current system may be overloaded or outdated, posing safety risks.

Your electrical panel should meet the safety standards set by the National Electrical Code (NEC). To ensure compliance, it should not have any rust or corrosion, all circuits should be clearly labeled, and there should be no signs of overheating or loose connections. An inspection by a licensed electrician can provide a definitive answer and identify any necessary upgrades.

To prepare for major electrical work, clear access to areas like the main electrical panel, outlets, and switches. Secure pets in a safe location and plan for potential power outages by saving work and protecting sensitive electronic equipment. Inform the electrician about any known issues or previous modifications to your electrical system.
