The purpose of this Practice is to provide a specification for the design and fabrication of outdoor enclosures that are provided as an integral part of enclosed equipment.

This Practice covers requirements for design, fabrication, testing and handling of free-standing outdoor enclosures housing low and medium voltage motor controllers and switchgear. The requirements of this Practice shall apply to walk-in and non-walk-in enclosures located in a non-classified area. This Practice is not intended for enclosures that will be located in classified areas. These enclosures are not recommended for use in corrosive, dirty, or dusty environments. These enclosures are not intended for climate-controlled or pressurized applications. When pressurized or insulated climate-controlled enclosures are required, see PIP ELSSG11.
