Inspect electrical panel

Visually inspect your electrical panel for signs of problems.

Why it matters#

Electrical issues caught early prevent fires and expensive damage. Regular visual checks can identify warning signs before they become dangerous.

Steps#

1. Approach the panel safely#

You're doing a visual inspection only. Never remove the inner cover or touch wires.

2. Check the panel exterior#

Look for rust, damage, scorch marks, or signs of overheating on the outside of the panel box.

3. Open the panel door#

Open the outer door to see the breaker switches. Do NOT remove the inner metal cover.

4. Look for tripped breakers#

Any breaker in the middle position (between ON and OFF) has tripped. Note which circuit it serves.

5. Check for signs of heat damage#

Look for melted plastic, discoloration, or scorch marks on or around any breakers.

6. Look for double-tapped breakers#

Check if any breaker has two wires connected where only one should be. This is a code violation.

7. Listen for sounds#

Put your ear near (not touching) the panel. Buzzing, crackling, or humming indicates problems.

8. Smell for burning#

Any burning or acrid smell means something is overheating—this requires immediate professional attention.

9. Feel the door (only)#

The panel door should not feel warm. Warmth indicates overheating inside.

10. Check panel labeling#

Is the circuit directory complete and accurate? Test a few circuits to verify labels match.

Pro tips#

Inspect annually and after major storms or electrical events
Keep 3 feet of clearance in front of the panel at all times
All household members should know the panel location and how to shut off power
Take a photo of your panel layout for reference during emergencies

Warnings#

Never remove the inner cover—live wires inside carry lethal voltage
If you see scorch marks, smell burning, or hear crackling, stop using affected circuits and call an electrician immediately
Federal Pacific and Zinsco panels have known safety defects—consult an electrician about replacement

Call a licensed electrician if you notice: scorch marks or burning smell, buzzing/crackling sounds, warm panel door, frequently tripping breakers, double-tapped breakers, rust or moisture, or if you have a Federal Pacific, Zinsco, or other recalled panel brand. Annual professional inspections are recommended for older homes.
