Split-bus panels, commonly installed from the 1960s to the early 1970s, feature two separate non-connected buses within the panel—one in the upper and one in the lower section. The primary issue with these panels is the absence of a single main disconnect breaker, preventing the simultaneous shutdown of all power during emergencies.
