How do you dry wet electrical wires?
Wiring can be dried by gently blowing warm air through the conduit, or removal and re-installation if necessary. Dry air is preferable, as it will remain essentially captured after the process is complete. Any humidity present in the air can leach back into the insulation.
Can water damage wires?
