Here are a couple of the references;
AS/NZS 3000:2000
4.9.1.3.1
Extra Low Voltage
Where an extra-low voltage electrical installation and an electrical installation of greater then extra-low voltage are in the same premisies, all socket-outlets supplied at extra-low voltage shall-
(a) have their voltage conspicuously marked;and
(b) be of a form that will prevent insertion of an extra-low voltage plug into a
socket-outlet connected to a circuit of greater then extra-low voltage.
Note: AS/NZS 3112 contains a specific plug and socket-outlet arrangement recomended for extra-low voltage applications.
4.9.1.3.2 SELV and PELV
Plugs and socket-outlets for SELV and PELV systems shall comply with clause
7.7.11.
7.7.11. Plugs and socket-outlets
Plugs and socket-outlets for SELV and PELV shall comply with the following:
(a) Plugs shall not be able to enter socket-outlets of other voltage systems.
(b) Socket-outlets shall not accept plugs of other voltage systems.
(c) Socket-outlets shall not have a contact for a protective earthing conductor.
From the above you can see that the answer to the original question (pin connection with respect to polarity) does not appear in AS/NZS 3000. As i have mentioned earlier the RECOMENDED layout is in AS/NZS 3112 which I do not have in front of me at present.
In the above quotes from AS/NZS 3000;
SELV means; Seperated extra-low voltage
PELV means; Protected extra-low voltage
Extra-Low Voltage means; Not exceeding 50 V a.c. or 120 V ripple-free d.c.
By using a battery or a stand-alone generator (the motor that drives the generator is not plugged into a mains supply) you are covered by the definitions SELV or PELV.
I will read AS/NZS 3112 and get the exact words for you.
