Abstract
Abstract In a power board, network transformers are disposed horizontally to reduce their height, network buses are disposed above the network transformers and a protector breaker and take-off breakers are disposed at the front of the power board in electric chambers and connected to the network buses. This arrangement places the two types of breakers and the electric chambers within the range of height accessible by an operator's hand to permit him to manually handle these breakers, thereby improving ease of handling of the power board.
