Breather vent for electrical enclosure |
摘要 |
A breather box attaches to the exterior wall of an electrical enclosure. An upper breather opening in the box connects with a vent opening in the wall. A lower breather opening in the box is shielded by a wall spaced therefrom to prevent water entry. A labyrinth in the interior of the box forces ascending water through a series of sharp turns and through a series of constrictions which are followed by expansion chambers. The labyrinth terminates at a liquid exit adjacent the upper wall of the breather box, forcing water to substantially fill the breather box before it can enter the enclosure.
