WIRE ENTRY ARRANGEMENT FOR COMPONENTS IN A PROTECTIVE DAM AREA OF A FOAM INSULATED ELECTRIC WATER HEATER TANK

摘要

An electric water heater tank defines a water chamber having an electrical component extending outwardly of the outer surface of the tank. A spaced outer jacket surrounds the tank and has a opening affording access to the component. A protective dam in the opening bridges the gap between the tank and jacket in surrounding relationship to the component and is covered by a cap extending over the component and engaging the dam. Electrical wires connected to the component extend outwardly of the jacket between the cap and dam. A door covers the cap and dam and is secured to the jacket such that the door engages the cap to force the dam into sealing engagement with the jacket and tank. Foam thermal insulation material fills the space between the jacket and the outer surface of the tank.
