Residual current devices

Without limiting subregulation (2), the residual current device must have a tripping current that does not exceed 30 milliamps if electricity is supplied to the equipment through a socket outlet not exceeding 20 amps.

Subregulation (2) does not apply if the supply of electricity to the electrical equipment — (a) does not exceed 50 volts alternating current; or (b) is direct current; or (c) is provided through an isolating transformer that provides at least an equivalent level of protection; or (d) is provided from a non-earthed socket outlet supplied…

A person with management or control of a workplace must take all reasonable steps to ensure that residual current devices used at the workplace are tested regularly by a competent person to ensure that the devices are operating effectively.

The person must keep a record of all testing of a residual current device (other than any testing conducted daily) until the earlier of the following occurs — (a) the device is next tested; (b) the device is permanently removed from use.

This regulation applies in the following circumstances — (a) electrical equipment is used in an environment in which the normal use of electrical equipment exposes the equipment to operating conditions that are likely to result in damage to the equipment or a reduction in its expected life span, including conditions that involve exposure to moisture,…

In a circumstance set out in subregulation (1), a person conducting a business or undertaking at a workplace must ensure, so far as is reasonably practicable, that any electrical risk associated with the supply of electricity to the electrical equipment through a socket outlet is minimised by the use of an appropriate residual current device.
