The RCD DUO has been designed to offer Fault to Earth protection on isolated power supplies such as Generators, Inverters and isolation transformers. The combination of the Earth Sensing Device and a traditional RCBO allows the unit to also protect the user when connected to a mains power supply. The RCD DUO can be fitted as a replacement for a traditional RCBO in existing installations such as caravans, generators, and switchboards.
