Label the breaker panel
Half the panels we open have at least one breaker labeled wrong or not at all. Someday you'll need the right one in a hurry, whether it's a sparking outlet, a leaking appliance, or a plumber on the phone asking you to shut off the water heater.

- Photograph the panel as-is. Cover open, before you touch anything. Your reference if you get lost.
- Find the main. The big breaker at the top (or a separate disconnect outside near the meter). Everyone in the house should know where it is.
- Work one breaker at a time. Flip it off. Your helper walks the house and reports what went dark: which room, which outlets, which appliance. Plug the lamp into outlets to be sure.
- Write it down as you go. Room and function, not just "bedroom." "Master bath outlets + fan" beats "bath." Number the breakers if the panel isn't already numbered.
- Note the dedicated circuits. Water heater, HVAC, range, dryer, and well pump are double breakers. Label them clearly; they're the ones you'll be asked to shut off.
- Finish the label and leave a copy. Fill in the directory card or apply printed labels, and tape a copy inside the panel door. Photograph the finished panel too.
When it's past the do-it-yourself line
Warm breakers, scorch marks, rust, a buzzing sound, or a breaker that won't stay on are electrician calls, not labeling problems. Never remove the panel's inner cover; the labeling job only needs the door open.
