26、eir way into the internal components of installed electrical products and may remain there even after the products have been dried or washed by the user. These may adversely affect the performance of those products without being readily apparent to the user community. Also, electrical products, such

27、 as GFCIs and surge protective devices, contain electronic circuitry and other components which can be adversely affected by water resulting in the device becoming non-functional or a hazard to the user. As a result, such products subjected to or believed to be subjected to water damage are not suit

28、able for continued use and must be replaced with new undamaged products. Air drying and washing of water damaged products of this type should not be attempted.” NATIONAL ELECTRICAL MANUFACTURERS ASSOCIATION 1300 NORTH 17TH STREET, SUITE 900 ROSSLYN.
