depending on the panel board, the main breaker can either be mounted horizontally or vertically.
A main lug only type panelboard does not have a main circuit breaker.the incoming supply cables are connected directly to the bus bars. primary overload protection for the panelboard is not provided as an integral part of the panelboard.
There are a variety of ways a main breaker or main lug only panelboard might be used in the same application. for example, Feed-thru lugs, mounted on the opposite end of the main bus from the main breaker, could be used to connect a main breaker panelboard to a main lug only panelboard.
The feed-thru lugs mounted on the main bus of main breaker panbelborad are connected to the main lug only panelboard. The main breaker protects both panelboards from overcurrent.
