Abstract: An improved frame for a switchgear cabinet includes a plurality of rails that are connected together with a plurality of connectors. The rails are generally of two different cross-sectional configurations, both of which are cooperable with a single type of connector to enable the rails and connectors to be configured into numerous different types of cabinet frames to which panels can be mounted to form switchgear cabinets. The rails and connectors are modular in nature and are specifically configured to be easily connected with one another. During assembly of the connectors and the rails, portions of a coating on the rails become ruptured, thereby electrically conductively connecting together the rails and the connectors.
