Insulating ribs are formed into one or more portions of a housing that encloses circuitry of an electrical device. Components mounted on a board are separated according to whether they are related to a primary side of a power transformer or a secondary side. Primary related components are typically mounted on the primary side of an isolation slot formed into a circuit board and components related to the secondary are mounted on the other side. The insulating ribs are strategically placed to protrude through the slots when circuit board is mounted to the housing portion. Thus, when the housing portion is joined to another housing portion, which also may include insulating ribs strategically placed, the ribs increase the breakdown voltage of the boundary.
