What Specifications Should Buyers Provide When Ordering a Custom Ring Main Unit?When ordering from a Ring Main Unit Manufacturer, buyers must provide more than voltage and current ratings. A custom RMU design depends on the network layout, fault level, enclosure location, protection method, cable size, and operating environment. The right information helps a custom ring main unit manufacturer select safe components, meet IEC requirements, and reduce changes during
