“Split bus” panel, older load centers do not have single “main” breaker, panel divided into 2 or 3 sections, “disconnect” section feeds power to lower section(s): The electrical panel is a “split bus” panel. These older load centers do not have a single “main” breaker. The panel is divided into 2, and sometimes, 3 sections. The “disconnect” section, usually at the top, feeds power to the lower section(s). They are required to be set up so that all power to the building’s circuits can be shut off using no more than six disconnects in the main section. This is called the “6-throw rule.”
