It will make it harder for designers to omit the use of RCDs from installations, a practice which puts safety at risk, according to one of the electrical industrys largest manufacturers. If a particular circuit is critical for safety services or business functions, surely socket-outlets would not be the preferred option, to prevent accidental "unplugging". The testing team will provide a detailed report that includes both the location of the safety switch and the results. The previous requirement for protection to socket outlets affected those with a rated current not exceeding 20A. Operating Voltage the Intended Voltage the RCD is designed to operate. The team carries out the testing and tagging adhering to the stringent Australian quality standards.
