• Turn off the main breaker before opening the panel to eliminate shock risk.
• Inspect breaker terminals for signs of discoloration or scorch marks.
• Tighten all terminal screws to manufacturer specs to prevent arcing.
• Check for double-tapped breakers to avoid loose wire connections.
• Inspect neutral and ground bars for corrosion or loose wires.
• Use a non-contact voltage tester to confirm no stray voltage is present.
• Look for moisture or rust that could cause short circuits or power loss.
• Identify any undersized breakers or wires serving large appliances.
• Test GFCI and AFCI breakers using their test buttons for safety circuit function.
• Trace the affected circuit and check for backstabbed connections at outlets.
• Note any buzzing or warmth from breakers to identify emerging failure.
