Clearance and Creepage Rules for PCB Assembly
Nodes within the same high voltage circuits at the same potential usually do not require increased clearance or creepage to each other, but do require clearance to low voltage circuits. A good method is to place high voltage circuitry on the top side of a board and low voltage circuits, often control and monitoring, on the bottom side.
