5.5 Flexible cord
Any flexible cord provided,other than that classified under Clause 5.6.5, shall—
(a)comply with the relevant requirements of AS/NZS 3191;
(b)be of the ordinary duty or heavy duty type;
(c)be of the appropriate current rating for the device and have conductors with a crosssectional area of not less than 0.75 mm’; and
(d)comply with Clause 8.3.
Every control device shall be provided with output facilities complying with one or more ofthe following forms:
(a)A socket-outlet complying with the relevant requirements of AS/NZS 3120 intended
to accommodate a three-pin, flat-pin plug conforming to AS/NZS 3112.
(b) one or more socket-outlets complyingwith the relevant requirements of AS/NZS 3112.For multiple outlet control devices,connected by flexible cord or anappliance inlet,which have socket-outlets intended to accommodate a three-pin,flat-pin plug conforming to AS/NZS 3112, the relevant requirements of AS/NZS 3112apply, except that on the plane of the socket-outlet faceplate——
(ithe minimum distance from the edge of any live-pin aperture to the edge of the faceplate shall be 13.7 mm; and
(i)the maximum distance by which the faceplate，within the distance specified inltem (i) above, is below the plane shall be 3 mm.
(c)A flexible cord directly connected to the control device and terminating in a Group 1
or Group 2 appliance connector complying with AS/NZS 60320.1, or a cord extensionsocket complying with AS/NZS 3120.
(d)Terminals and cord anchorage facilities suitable for connection to a flexible cord.
Such facilities shall satisfy Tests Nos 4 and 5 of Table 2 when applied to the cord orrange of cords intended for connection to the control device.
The control device may incorporate one or more lampholders provided that—
(a)the maximum connected lamp load does not exceed 10% of the control device rating;(b)any lamp is protected by a substantial guard or enclosure which cannot be removed
without the use of a tool, this does not preclude the use of a hinged cover intended tofacilitate lamp replacement; and
(c)any lampholder is of the all-insulated type as defined as AS/NZS 3100.
Where a bayonet cap or edison screw lampholder is provided, it shall comply with therelevant requirements of AS/NZS 3117 or AS/NZS 3140 respectively.
Any lampholders provided shall be controlled by a Category 1 switch except that the ‘OFFposition need not be marked.
5.6.3 Overcurrent protection Any control device having three or more 10 A socket-outlets or a socket-outlet or terminals for the connection of a flexible cord rated in excess of 10 A shall be provided with manually resettable trip-free overcurrent protection having a current rating not exceeding the rated current of the control device and which complies with Clause 10.5, except where the means of overcurrent protection is a miniature overcurrent circuit-breaker complying with the relevant requirements of AS/NZS 3111.
Not more than one socket-outlet rated in excess of 10 A shall be incorporated in a control device.
Fuses shall not be used as a means of overcurrent protection.
5.6.4 Switching requirements
If switches are provided the switching arrangements shall be one of the following:
(a) A switch or a miniature overcurrent circuit breaker or a cord-line switch which controls all output facilities and which is rated at not less than the current rating of the device. (b) A switch controlling each outlet facility or socket-outlet provided each switch is rated at not less than the current rating of the outlet facility or socket-outlet it controls. Switches shall be multi-pole and shall be of one of the following types—
(i) a Category 1 switch as described in AS/NZS 3100 except that the ‘OFF’ position need not be marked; or
(ii) a miniature overcurrent circuit breaker complying with AS/NZS 3111 or AS/NZS 60898.1; or
(iii) a cord-line switch complying with AS/NZS 3127 and located in the supply flexible cord at a distance not exceeding 1.8 m from the device. Control devices shall be provided with switching arrangements if they are—
(A) fitted with a supply cord described in Clause 6.1(a), the length of which exceeds 1.8 m; or
(B) provided with means of connection described in Clause 6.1(b).
A control device with only one output facility or socket-outlet, with or without any lampholder as described in Clause 5.6.2 need not be provided with a switching arrangement. Switches which perform a control or conditioning function only, need only be Category 3 switches and may be single-pole and the ‘OFF’ position shall not be marked. Other control devices which perform a control or conditioning function need only be single-pole and the ‘OFF’ position shall not be marked.
