This paper from ASCO Power Technologies explains that transfer switches provide important functions by transferring loads to alternate sources when power outages occur. Both the functions they provide and the energy they manage require their safe operation. Because contact with water can degrade transfer switch condition and performance, it is important to understand how water-damaged equipment can impact facilities. Water ingress into transfer switches and other critical power equipment can impact operability, reliability and service life. This document summarizes measures for mitigating water-related risks throughout the equipment lifecycle.
