Foreword This is an update to the NEMA white paper Protection of Receptacle Outlets in Wet Locations-According to the National Electrical Code® (NEC). To ensure that a meaningful publication was developed, draft copies were sent to a number of groups within NEMA having an interest in this topic. Their resulting comments and suggestions provided vital input prior to final NEMA approval and resulted in a number of substantive changes in this publication. This publication will be periodically reviewed by the Joint Conduit Fittings and Outlet & Switch Boxes Group of the NEMA Commercial Products Division, so that it stays up to date with advancing technology.
