The problem
What actually goes wrong
Electrical equipment fails from moisture in two ways: insulation resistance falls until a fault develops, and condensation on terminals drives tracking and corrosion. Installed equipment in unconditioned buildings is at risk continuously, not just in transit.
The answer
Desiccant in the enclosure during shipping and storage, breathers on equipment that vents, and indicator cards to confirm that sealed cabinets are actually staying sealed.
The method
How to get this right
A repeatable sequence, in the order that matters. Skipping the first step is the usual reason the rest disappoints.
Our recommendation: Desiccant bags for sealed cabinets, indicating breathers for vented plant, indicator cards in both so condition is visible without opening.
-
Separate transit from installed risk
Transit needs a consumable charge; installed equipment needs a regenerable one.
-
Check enclosure integrity
An IP-rated cabinet still breathes through cable glands unless they are properly sealed.
-
Charge the enclosure
Desiccant sized to internal volume, placed in the air space rather than against components.
-
Fit breathers where it vents
Vented equipment needs the incoming air treated, not the enclosure charged.
-
Monitor
An indicator card inside the cabinet shows whether the seal is holding between services.
