[Verse 1] List the room, lamp in the outlet, helper on the switch Flip one breaker, walk what went dark, write it while it’s still which Avery 5163 or paper and tape QR that still works when the phone has no signal and the power’s late [Pre] Panel and number, poles and amps Directory card on the door so the next guy doesn’t guess [Chorus] Know what every breaker does Write it where the next guy can see it Flip one breaker Circuit Mapper, don’t leave the deadfront blank [Verse 2] Restore and repeat till nothing’s left unidentified Two-pole spans 30-32, type it so it isn’t a lie Export the JSON, keep the last twenty saves Beta or not, the fire doesn’t care about your brand of sticker [Chorus] Know what every breaker does Write it where the next guy can see it Flip one breaker Circuit Mapper, don’t leave the deadfront blank [Bridge] Building number, not a cell Tape it where it stays If you scan it in the dark It should still tell the truth [Chorus] Know what every breaker does Write it where the next guy can see it Flip one breaker Circuit Mapper, don’t leave the deadfront blank
