Learning From Failure in the Trades: Ladders, Wiring and an Attic Unit

First, a tech with a shaved head, a dark beard and ear protection walks past a SwiftPro van in a driveway, carrying a tall ladder with a meter pouch on his belt.

Then a close-up of hands wiring under a sheet metal cabinet. A multimeter like the one in that pouch is how a tech proves the power is off before touching a wire, and finds the bad part instead of guessing.

Last, a young tech with curly hair in a maroon long-sleeve shirt slides a unit into position in an attic. Moving equipment across joists without stepping through a ceiling is a skill you learn the first time you almost don't.
