Abstract
A two-tier cover assembly for a field service box. The two-tier cover assembly can be retrofitted to an existing field service electrical box to protect the electrical device that is housed therein. The cover assembly provides two configurations for protecting the electrical box, including an expanded and a collapsed configuration. In the expanded configuration, the cover assembly provides two cord openings that are accessible with the cover plate closed. In the collapsed configuration, the cord openings are completely closed to seal all openings and thereby protect the electrical device from rain, dirt, insects and other hazards.
