The present invention proposes a production support method and system for power control panel production automation, which enable an intention of a designer to be sufficiently reflected on a production site and an error occurred during production to be minimized and, in particular, includes the steps of: realizing, in a virtual environment, a power control panel designed in a 3D type and verifying an error by simulating wiring path information of designed components and electronic units; extracting production data for each process, including component information for each process, component and electronic unit arrangement information, assembly process information, and wiring information, by collecting information distributed to support production automation of the power control panel designed in the 3D type, which has been verified; and automating production by applying the production data to each interworking production facility to support the production automation of the power control panel.
