Regulations differ widely from country to country. A single RCD installed for an entire electrical installation provides protection against shock hazards to all circuits, however, any fault may cut all power to the premises. A solution is to create groups of circuits, each with an RCD, or to use an RCBO for each individual circuit. In Australia, residual current devices have been mandatory on power circuits since 1
