I walked in and killed the main breaker. I pulled the switch out and held a magnifying glass to the side of the nylon body of the switch. There it was. A crack no wider than a human hair, running from the hot screw to the ground yoke.
Here is why finding that crack before the power turns on is the most important skill in the trade.
We’ve all heard the saying, “A stitch in time saves nine.” In the world of electricity, that stitch is your eyesight. There is a specific, dangerous moment in the lifecycle of any electrical component: the moment it cracks.
When the house settled at night, the stud wall would flex, the crack would open by a millimeter, and the circuit would break. When the sun warmed the house, the plastic expanded, the crack closed, and the light worked.
We couldn't measure that crack with a meter. We had to it.
Electricity is invisible. Safety is visual. Don't just look at the wires; stare at the cracks.
