Determining the Feeder Routes

During the engineering installation phase, the layout of the feeder should be

determined according to the feeder wiring drawing among the engineering design

drawings. If the layout of the feeder need be modified as per the practical situation, you

should consult the user representative and try to solve the problem as early as possible.

Please note that the length of the main feeder should be as short as possible.
