Type a device, fixture, or outlet. Badge shows breaker number, column, and handle position (Left / Right on split breakers).
No match. Try a broader term (room name, "outlet", "light") — or it may be the unidentified circuit on 10-Left.

Before You Work — 60-Second Procedure
Look up the device above — note breaker number, column, and Left/Right position.
Turn the device on (or plug a lamp into the outlet) so you can see it lose power.
Flip that handle off. On split breakers, flip only the correct half. Confirm the device died.
Verify dead at the point of work with a non-contact voltage tester — always. Circuits here cross rooms.
Tape a note on the panel ("work in progress — do not switch").
When done, restore the handle and test GFCI outlets (living room right-of-pillar is GFCI).
Flags
BREAKER 10 — LEFT HALF UNKNOWN. The left handle of split breaker 10 is untraced. Do not assume anything is dead on it; identify with a helper and a plug-in tester, then update this page.
DECOMMISSIONED 220V HEATER CIRCUITS — DO NOT USE. 16-Left, 14 (both halves), and 12-Left served wall heaters that have been removed. Treat as abandoned; do not repurpose without an electrician.
