An object of the present invention is to provide a power feed control device with the ability to improve electrical insulation properties between respective lead pieces of first, second, and third sub-bus bars. A body of a power feed control device includes a housing recess to house a module (115) including a holder (50), the first sub-bus bar (12), the second sub-bus bar (22), the third sub-bus bar (32), and a zero-phase-sequence current transformer (8). Lengths of respective extended pieces (12d, 22d, and 32d) of the first sub-bus bar (12), the second sub-bus bar (22), and the third sub-bus bar (32) are different from each other. The holder (50) includes a rod portion (55), a post portion (56), and an extended portion (57). The extended portion (57) covers the respective extended pieces (12d, 22d, and 32d) of the first sub-bus bar (12), the second sub-bus bar (22), and the third sub-bus bar (32).
