Knows exactly which wire to not touch, and touches it anyway with confidence.

means A person with specialized practical skill in a technical field, who fixes, operates, or maintains the equipment the rest of us just stare at helplessly.

from From Greek 'tekhne,' meaning art, craft, or skill — the same root behind 'technique' and 'technology.' The Greeks used it for any skilled making, from pottery to rhetoric; 'technician' emerged much later as English needed a word for people who'd mastered a tekhne of their own, usually one involving wires, machines, or things that hum ominously.
