Abstract
Electrical equipment is housed in a cabinet and is protected against hurricane-force calamities by covering the electrical equipment with an inner door system inside the cabinet, and by closing an opening of the cabinet with an environmental door system, and overlaying that environmental door system with a calamity-proof door system that may be used as an on-site temporary roof for installation and service personnel in an upturned position, and that constitutes a protection against hurricane-force calamities in a closed position on the shut environmental door system.
