Abstract
An electrical enclosure includes a frame and a seismic subframe. The seismic subframe includes vertical frame members interconnecting with braces at the top and bottom and opening at the front and rear of the enclosure. The assembly mounts to the rectangular frame of the enclosure. Grid straps extend from front to rear to connect the assemblies and provide additional bracing. Front and rear panels include gusset type braces at the corners mounted to the panels that engage inner edges of the framework to provide positioning as well as support.
