・The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one size thicker in diameter. Make sure the
power-supply voltage does not drop more than 10%. Make sure that the voltage imbalance between the phases is 2% or less.
・Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57).
For example, use wiring such as YZW.
