Warning
primary power
Three-phase input power must be provided from a line (wall) disconnect switch that contains fuses or circuit
breakers in accordance to local or state regulations.
Sizes per National Electrical Code for a 90° C (194˚ F) rated copper conductors @ 40° C (104˚ F) ambient. Not
more than three conductors in raceway or cable. Local codes should be followed if they specify sizes other
than those listed above.
To estimate the input current for a wide range of output conditions, use the formula below.
