Electrical panel care stays mostly in the owner's hands at the surface. The cover stays closed, and the work inside belongs to a licensed electrician. Your job is to keep the area open, the labels honest, and the notes complete.
Keep the working space clear
Walk up to the panel and look at the area in front of it. Nothing should be stored there. Shelves, bins, hoses, and boxes all block access. Keep the clear space the panel's label or your local code calls for, and keep the door of the enclosure free to open fully.
Check the labels
Read each breaker label and compare it to the room or the appliance it feeds. Correct any label that is wrong, faded, or missing. If a circuit has been changed, update the label the same day you learn about the change.
Test the protective devices
Many panels have ground fault or arc fault devices. Use the test button each device's label describes, and check that the device trips and resets. A device that does not trip, or that will not reset, is a call for an electrician, not a reason to bypass it.
Watch and smell
Note any warm spot, buzzing, burnt odor, discoloration, rust, or water near the panel. Do not open the cover to look. Turn off nothing you are unsure about, and call a licensed electrician.
Keep a short record
Write down each breaker trip that happens without an obvious cause, each new appliance or outlet added, and the date of the last test you ran. This record is what an electrician will ask for first if you call for help.
What stays with the trade
- Opening the cover, changing breakers, or working on wiring
- Assessing whether the panel has the capacity for new loads
- Adding a circuit or a new panel
- Any permit or inspection
