I am wanting to have the aircon wired via a switch that I can reach from my van recliner. It appears that the aircon is wired directly to the AC power. I think the van AC is a plug and play system with CMS components.
Suggestions please.

If you get your A/C put to a 240V point you can then get a remote control power board. My TV, sound system, WD media box etc in the bedroom are in the remote plug board. If I leave all devices on idle in the bedroom it is lit up like Luna Park. Gives me the ability to switch all off and not have their standby lights glowing.

Sorry I cannot help, I was wondering about a relay next to the switch to do the remote switching, but that is for our electricians to suggest, not me.

Depends on current draw of the Air con
; what is it,s current rating??
There are a number of remote controlled POWER boards 10A rated with short cord & those should be DP switched to have an Australian approval
A plug in adapter type is also available but I doubt that it would be double pole switched, as it is not required for fixed wiring in houses etc

Ralph, ours is a Coleman Mach, Airxcel 9000 series unit. Nowhere in the documentation I have does it tell me the Watts or current draw. I would assume (dangerous I know) 10 amp at 240v. It must be wired directly to the plug and play system through the ceiling. No seperate switch or fuse.

Hi Paul
Am I correct in thinking that the unit has no plug & socket ,Just a cable gong through the wall
Surely ,No one would have done that????
That is playing the plug & play system to the Extreme.!!! It should have terminated with a switched plug & socket[which are available for the system]
Is there access to the connection within the wall?
Does it have any flexible cable accessible?

Just had a new unit installed at the house and the sparky told us that although it's not illegal to have a powerpoint type plug in if that plug came with the unit, but it is not legal to add a plug in lead to an air con unit. If it is not a plug in type then it must have an isolation switch near the outside unit if a split system or a separate circuit breaker supplying only that circuit if it is an all in one unit.
The wiring laws just seem to get stranger and stranger the further technology advances. Not very long ago no one would have dreamed of a plug in wiring harness but it is very common practice now with double adapter plugs into other double adapter plugs all sealed up inside the wall cavity, just about all room sized air con units plugged in to a power point but now there are laws to say if it didn't come with a lead you can't add on, it must be hard wired.
As for the double pole switch, have a close look at the switch wiring shown in the last photo, sure doesn't look like a double pole switch but rather a neutral wire designed to light up the switch in the one position.

Hi Terry
Still have not got the latest rules
But I think the situation would be that the ones sold without extension lead & plug have load currents in excess of 10A & therefore would require a 15A socket OR be hardwired .
If Hardwired, obviously Shall have an isolating switch in close proximity & easily accessible , in accordance with the Standards for many years
However ,Hard wired mean exactly that:Fixed hard wiring , using approved cables ,all the way into the appliance. Not every day 3 core flexible cable
Regarding the multi plug sockets & plugs in the system,THEY are NOT every day plugs & sockets .
They are specially designed & approved plugs & sockets with safety features built in for that type of situation
NOT just every day plugs & sockets.
Designed & approved to a specific standards which would cover, pull out , short term overload capacity,
By the apparent size of the flex from the aircon It would seem to be not 10A cable, Air co max load current in excess of 10A.
I agree that Switch certainly does not appear to be DP
Paul
Heaving seen more of the wiring & before any more advice can be given regarding remote control .we really need to know the rated current draw of the air con .
if it no more than 10A, there are some reasonably easy changes that a competent electrician could make to give you your remote control
If it is in excess of 10A It become a little more complicated, but I believe doable.
It also comes down to $$$

An interesting question arises, if a single pole remote switch is plugged into a double pole switched powerpoint, where have the standards been breached? Clearly the air con unit pictured previously only has a single pole switch so the plug in appliance rule seems to apply there, so why would it not apply to the remote switching device plugged into the double pole powerpoint?

Not sure what you men by a single pole remote switch, but if you mean the remote control supplied with the aircon & switching the air con internally ,it does not need to be double pole as even if it is not switched on ,there would still be some live wiring inside the aircon ,reason an external switch is always required
Note; it applies to all device with remote on /off controls ,this something many are not aware of ,yet can be a source of failure & possibly fire if loss of insulation occurs between active & earth anywhere within the appliance . TVs. air cons ,anything that has a remote power control.
Now if you mean a remote controlled outlet permanently wired into mains supply,house etc, it only needs to be single pole because the electrician installing should check that He has not got the polarity wrong
But that is the reason such are not approved for vans etc [connected by plug & socket to the supply
Now back to Air cons in Vans etc :
They must always have & have always required a double pole isolating switch, even if fixed wired & of course if plug & socket connected the outlet will/must be /SHALL be DP switched
Portable remote controlled outlet boards plugged into any outlet socket will be /must be/SHALL be double pole switched in all situations
Think of this : someone decides to play around inside their air con & for safety decide to switch off the single pole switch only, either manual or remote controlled,
What could be the consequences????
All the varying requirements of the Standards make sense if one looks @ the total picture

Ummm....... Peter, check out any van that has both 12v light switches and 240v light switches located close to each other, the wiring is not double insulated or separated by the required distance, yet this has been the norm for ever. The electrical safety mob know full well this is standard practice along with the one visual inspection covers every van/RV made by that manufacturer and have no interest in policing any of it.

HI Terry
RE""The electrical safety mob know full well this is standard practice along with the one visual inspection covers every van/RV made by that manufacturer and have no interest in policing any of it""
I think you should say that only seems to apply to Victorian makers in Vic
Wa ,Qld & I believe now NSW , All now clearly stating that van 240V wiring is licensed electrical work
Not sure about SA
But even Vic would take action against such a blatant disregard for the regs as using SP switching
The only hope is to keep pressure on the Vics to comply with the Standards & report such situations
RE "just about all room sized air con units plugged in to a power point but now there are laws to say if it didn't come with a lead you can't add on, it must be hard wired.""
I think your electrician may not clearly understand the rules
If the Air con does not come with a correctly attached flexible cable & Plug ,only a LICENSED Electrician can fit a flex cable & plug Ensuring that the cable is fitted & restrained in an approved manner to the air con
A rule/ Regulation that has existed for a loooooong time
Other the years, I have found too many electricians who cherry pick clauses or do not read/understand the rules in their entirety
Some seems to be only able to read one sentence & not retain other requirements pertaining to the same rule
My son has just such a young expert on every thing, working under him
Last week he had another instant to send him back to do a simple job properly
He had the job of testing insulation resistance, circuit loop impedance & earth continuity on a high current [100s of amps]multi circuit Switchboard. before it was submitted as complete [Part of a major contract for a Gov Department]
Came back with just three readings on the check list, this despite that there were multiple circuits ,differing cable sizes & types,each with their own protection & where of greatly differing lengths
Quite upset when son said now go back & do the job correctly
Could not understand why son would put his signature to it.

Hi Paul
IF that is the switch controlling the air con, it certainly is not DP!! & definitely will not/does not /cannot comply to the Standards /Rules /Regulations.
Even if is switching some other 240V ,it does not comply!!
If your van does not comply, there must be more out there with the same situation .
For your own safety & that of others ,You should report it direct to your nearest Electrical safety office. Do not report it to the van maker!!
There are multiple reasons why all such switchs SHALL be DP
Let the ESO investigate & do their job.
It may lead to a long overdue shake up of the industry!!
Re that Amp meter reading ,There must be still something connected & it is not just leakage ,as it amounts to nearly 190 Watt or 190VA load

That's what I meant, contactor/relay same thing, same as the starting contactor for a 3 phase motor, the coil could be 12v, so once the contactor is installed, Paul could put his switches anywhere. The electrician needs only to install the contactor.
How about those light switches Jayco use, I think they are wireless, haven't pulled one off the wall ------- yet!, but they would pass enough current to energise the contactor coil.

IF Paul is happy with a switch on a lead,there are simple options including a simple 240 volt rated DP relay fitted with a 12V coil
The remote controlled light switch will only be single pole & the switching cannot be isolated from the 240V [with a current rating of 5A ]

Re that Amp meter reading ,There must be still something connected & it is not just leakage ,as it amounts to nearly 190 Watt or 190VA load
NOT just any old 12V latching relay.
And it would not need to be a latching relay if you have an on /off switch on a lead for the 12V coil & still an electrician job to do the 240V wiring to it
How about those light switches Jayco use, I think they are wireless, haven't pulled one off the wall ------- yet!, but they would pass enough current to energise the contactor coil.
IF Paul is happy with a switch on a lead,there are simple options including a simple 240 volt rated DP relay fitted with a 12V coil
The remote controlled light switch will only be single pole & the switching cannot be isolated from the 240V [with a current rating of 5A ]
Thanks everyone.
Ralph, the current was the fridge I thought was turned off!!!
That switch is the mains isolator switch. pic attached.
Ok re reporting to appropriate authority.
I have a sparky nephew who does my 240v work.
Aussie Paul.
Hi Paul
That is Ok for the main switch .It is Double pole
But that "'Switch"??? that Terry & I am referring to is not the rear wiring of the Master Switch
Suggest you get nephew to check that ALL switchs [& especially the AIR con On /Off switch] are double pole
