Protection against earth faults

In Australia as well as in global markets, electrical safety authorities have advocated the wide use of residual current devices (RCDs), also known as safety switches or earth leakage devices, as an effective means to provide protection against the threat of electric shock.

The Australian and New Zealand Wiring Rules, AS/NZS 3000, require active conductors to be protected by one or more devices that automatically disconnect the supply in the event of overcurrent, before such overcurrent reaches a magnitude or duration that could cause injury to people or damage the installation due to excessive temperatures or electromechanical stresses. This whitepaper unpacks the technical details, requirements and types of RCDs available to support those working within the electrical industry, and importantly provide guidance on choosing the right RCD for different applications.
