Code of Practice for the Electricity (Wiring) Regulations - 2009 Edition

6G Final Circuits Using 16A Industrial Socket Outlets to
Requirements Prescribed in Appendix 4
(1) Socket outlets
These are industrial socket outlets with retaining devices for either indoor
or outdoor applications and are for single-phase or three-phase supplies.
(2) Accepted practice
(a) Only radial final circuits should be used.
(b) Fused or non-fused spur is not allowed.
(c) The current demand of the equipment fed by the circuit will depend
on the type of equipment and the operational requirements, and
should not exceed the rating of the overcurrent protective device.
(d ) The overcurrent protective device should have a rating not exceeding
20A.
(e) The number of socket outlets can be unlimited.
(f ) Figure 6(5) illustrates such a circuit arrangement.
6H Final Circuits Using 32A, 63A or 125A Industrial Socket
Outlets to Requirements Prescribed in Appendix 4
(1) Socket outlets
These are industrial socket outlets with retaining devices for either indoor
or outdoor applications and are for single phase or three phase supplies.
(2) Accepted practice
(a) Only exclusive radial final circuits should be used.
(b) The number of socket outlets in a final circuit should not be more
than one.
(c) The overcurrent protective device should have a rating not exceeding
the rating of the socket outlet or that of the cable forming the
circuit.
