Section 5 - Guidelines

Recommended Use of Residual Current Devices (RCDs)

(43) It is recommended that RCDs be installed to protect power outlets in areas defined as high risk and any hostile environments.

(44) Note: The requirements for the installation of RCD safety switches as required by relevant legislation (Codes and Standards) is mandatory for new installations.

(45) The use of portable RCDs must be employed in all situations where the use of portable equipment is used as part of the workplace in a number of locations. Examples include portable vacuum cleaners, maintenance equipment or laboratory equipment in some experimental applications.
