This presentation serves as a guide that represents the consensus of NEMA member companies and provides information on how to evaluate electrical equipment that has been exposed to water through flooding, fire-fighting activities, hurricanes, and other events involving large quantities of water. It is designed for suppliers, installers, inspectors, and users of electrical products. Electrical equipment exposed to water can be extremely hazardous if reenergized without performing a proper evaluation and taking necessary actions. Reductions in the integrity of electrical equipment due to moisture can affect the ability of the equipment to perform its intended function.
Damage to electrical equipment can also result from flood waters contaminated with chemicals, sewage, oil, and other debris, which will affect the integrity and performance of the equipment. Ocean water and salt spray can be particularly damaging due to the corrosive and conductive nature of the saltwater residue. This presentation will outline the equipment that may need to be replaced or could be suitable for reconditioning after exposure to water.
