This invention relates to cabinet enclosures for electrical apparatus such as electrical switching apparatus which may be used as service entrance equipment or similar apparatus positioned ahead of a watthour meter. Such enclosures are sealed shut by an electrical utility to prevent unauthorized access to electrical power. More particularly, the invention relates to such apparatus wherein the cabinet is provided with an internal barrier overlying the electrical apparatus providing limited access to the apparatus through an open side of the cabinet. An external cabinet door closes off the open side of the cabinet. Both the door and the internal barrier are sealed by the utility to restrict the unauthorized taking of electrical power from the apparatus.
It is preferred or desirable that the seal for the internal barrier be visible and inspectable from the exterior of the cabinet indicating that the internal barrier is in place, has not been tampered with and is still sealed without breaking the seals for the door and opening the door to visibly inspect the barrier and its seals.
