Building projects requires MV Distribution Panel Boards for distribution of power to each utilities. A good electrical distribution network will have proper design, right components, and future load provisions. Space utilization will also be an important factor for maintenance and handling of the equipment. Here we look into what are the features required for design, manufacture, install a MV Distribution panel board including its BIS (IS) standards that serving quality building projects.
