Abstract
A non-metallic enclosure for electrical apparatus has a housing and cover with a door pivotably mounted on the cover. A hood is attached to the housing such that when the door is attached to the cover and the cover is attached to the housing at least one pivotable connector will be behind the hood so that the door can only be nondestructively removed by removing the cover from the housing. Electrically conductive connectors and resilient snap-in members are preferably molded into the housing to secure bus bars and neutral bars to the housing.
