South Australian Consolidated Regulations (1) Subject to
complying with any requirement of a preceding regulation under this Division,
any risk associated with the supply of electricity through a socket outlet
must be minimised so far as is reasonably practicable by the use of an R.C.D.
(2) If the supply of
electricity in any situation in a workplace is through a socket outlet not
exceeding 20 amps to—
(a) hand
held electrical plant; or
(b)
electrical plant that is moved while in operation; or
(c)
electrical plant that is moved between operations in circumstances where
damage to the electrical plant or to a flexible supply cord could reasonably
occur; or
(d)
electrical plant where electrical safety could be affected by the operating
environment,
the electrical plant must be protected by an R.C.D. with a tripping current
not greater than 30 milliamps.
(3) An R.C.D. under
subregulation (1) or (2) must be—
(a) for
a new electrical installation—a non-portable R.C.D.;
(b) for
a new or modified circuit on an existing electrical installation—a
non-portable R.C.D.;
(c) for
an existing electrical installation where paragraph (b) does not
apply—either a non-portable R.C.D. or a portable R.C.D., where a
portable R.C.D. is connected at the socket outlet supplying electricity to any
electrical plant.
(4) An R.C.D. must be
provided for any final sub-circuit on a construction or demolition site within
the scope and application of AS/NZS 3012 Electrical
installations—Construction and demolition sites .
(5) The requirement
for an R.C.D. does not apply where—
(a) the
supply of electricity is to an extra low voltage system that is electrically
separated from earth and from other systems in such a way that a single fault
cannot give rise to the risk of electric shock; or
(b) the
supply of electricity is to electrical plant and is—
(i)
direct current (DC); or
(ii)
provided through an isolating transformer that complies
with AS/NZS 3108 Approval and test specification—Particular requirements
for isolating transformers and safety isolating transformers ; or
(iii)
provided from a portable generator that complies with AS
2790 Electricity generating sets—Transportable (up to 25 kW) .
