CURRENT MEASUREMENT UNIT, CURRENT MEASUREMENT UNIT FOR DISTRIBUTION PANEL AND DISTRIBUTION PANEL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a current measurement unit, a current measurement unit for a distribution panel and a distribution panel using the same that can measure load current with high precision even when a displacement occurs between conductors in a manufacturing process.SOLUTION: A current measurement unit 5 has a board 51 having plural conductive layers. Conductors (first conductors L11, L41 and second conductors L12, L42) which are electrically connected to each other are formed on at least two layers out of the plural layers. Sites of the conductors which are overlapped with each other when viewed from the thickness direction of the board 51 are formed to have a width dimension which is equal to or larger than a permissible error for the relative positional displacement between the conductors in the direction perpendicular to the thickness direction.
