After spending more years than I care to admit to in the RV industry, one of my greatest annoyances is the amount of incorrect information that is distributed.
Please check out VSB1, ADR 42/04 clause 9, AS 2513-1982 and AS 4177.5 - 2004 and you'll see that only seven pin (three types) and twelve pin connectors meet the standards. In fact this has been the case since 1982. Whether other types are in use is immaterial. If you are going to educate the masses please get the story right.
As the 7-pin connectors follow an International code, number 2 is designated as 'reversing signal'. As these are not required on trailers in Australia, this becomes a spare pin. But it is not suitable for providing current for the fridge or charging a battery as a standard 7-pin plug is only rated at 10amp. Either use the larger pins in a 12-pin plug or fit an Anderson plug/socket.

Thats what
mine has as the van has reversing lights.
What I am going to do is use it to charge the brakesafe only and have run 6
B&S to charge the batteries and have an 8 B&S to power the fridge.
Seems more sensible than having a 6mm trying to charge the batteries (2 x 100ah)

what ever is written in the australian standards IS NOT LAW
take for instance...SAPOL and their NON certified lab which calibrates the cameras and radar yet the fines still stand
also as another example...AS3666 for prevention and control and Legionella
You can do what you like ....but if anyone gets affected by legionella form your premises and you have not followed the AS3666 (or better) then you may get pinched if found negligent
same for all AS...it is not a law as such

Hi MN1,
Not necessarily true: "same for all AS...it is not a law as such" AS3000, the Electrical Wiring standard is most certainly enshrined in law.
Most of the Australian Standards are as you say, best practice guidlines. The odd one or two such as AS3000 are law.

The Australian Standards are only LAW if they are called up in an Act or Regulation.

agree Sir Kev
most standards are recommendations and the law usually calls it up "as is" thereby making it law
OR
as we use quite often we call up the intent of the standard where it not always prescriptive

"the law usually calls it up "as is" thereby making it law" Exactly my point and the case with AS3000!
Therefore AS3000 is effectively a law and a standard.
Which is how the local electrical retailer, ie, Energy Australia, Ergon, Country Energy etc get to say whether an electrical installation can or cannot be connected to the
grid.
I wonder how this will be enforced if the NSW Government get there way and sell the retailers off to private enterprise? (Just thought of that as I was typing the third sentence!) I'll bet our rocket scientist NSW pollies haven't even got a clue this is necessary!

It'll be interesting just what weight are put on "Standards" by the government in the light of the Insulation debarcle. There'll be a lot of ducking, weaving and "interpretation".

If an Australian Standard is referred to in the ADRs and the ADR is absorbed in the relevant Acts (as is the case here) the Standard can be enforced.
ADR 42.04
9.2. Electrical Connections
9.2.1. Except for motor vehicles over 3.5 tonnes ‘GVM’ and trailers over 3.5
tonnes ‘ATM’, the electrical connectors between motor vehicles and
trailers, for the purpose of operating the prescribed vehicle lighting and
signalling must comply with Australian Standard 2513 – 1982 “Electrical
Connections for Trailer Vehicles”.
