Split-bus panels, commonly installed between the 1960s and early 1970s, consist of two separate non-connected buses in the upper and lower sections of the panel. The critical issue with these panels is the absence of a single main disconnect breaker, preventing the ability to shut off all power at once during emergencies. Instead, up to six “mains” might be present, requiring individual shutdowns. Given their outdated installation and age, remaining split-bus panels in older homes may not operate safely. Identifying a split-bus panel involves opening the electrical box’s front cover and observing breakers divided into two groups.
