According to NEC Article 230, how must service equipment be mounted?

Service equipment must be securely mounted on a structure or concrete pad to ensure safety and proper functionality. This requirement is in place to protect the service equipment from environmental factors, accidental damage, and to provide reliable connections for incoming electrical service. When mounted securely, the risk of movement or disconnection during extreme weather conditions or seismic activity is significantly minimized.

Mounting service equipment on a solid foundation, such as a structure or concrete pad, ensures that it remains stable and in a fixed position, which is essential for maintaining the integrity of the electrical connections and preventing any potential hazards. Proper mounting also allows for easy access for maintenance and emergency shutoff if necessary, complying with safety standards established by the NEC.
