Hi guys
Picking up a van today and the kids want to sleep in it tonight as kids do! I have the caravan power lead, what do I need to plug into the house power, or is it not safe? I remember my neighbour had a converter or something like that but hes in papa new guinea! thanks
Justin

Hi Justin,
if the house has a safety switch inside the meter box (test it by pressing the test button, before relying on it), then the extension lead to caravan is safe.
If there's no safety switch in the meter box, you can buy a plug-in-style unit for your extension cord.
cheers, Peter

Thanks for the post Peter, house has a safety switch and tested and reset in many times. The van extension lead (the one for parks) has a larger end that doesnt fit into household power points?

Most make a 15-10 amp jointer cable (Which is illegal)
Safest way is to get a sparky to put a 15 amp socket in your outside switchboard.
The only legal way other than that is to buy a device called an Amp-fibian

Would be a shame to lose house or van or kids by using an unsafe connector which may nullfy any insurance claim.
Does van not have batteries to keep lights going for 1 night if needed

reminds me what reckless/irresponsible things I did earlier...
Angle grinder came out and shortly after, the wide earth pin fitted snugly in a 10A rated GPO.
Of course I was keeping any load currents below the 10A rating and everything was dandy.

A grinder is overkill isnt it. Even running below 10 amps doesnt make it legal
Also
ruins a good cord which may be disallowed if
camp owner decides to check as some do.
We have ours stored and plugged into a 15 amp socket
I prefer to sleep soundly.

Mind you, my recklessness dates back to the dark ages where safety switches weren't mandatory yet.
In an act of random wisdom, I invested in a plug-in-style RCD, in connection with the modded extension cord.
This resulted in a setup which was inherently safer than any law compliant setup.
My sleep was as good as it gets.....

Yeh that must be what the neigbour has, its an older van, no batteries I think, might just try to find some battery powered lamps or something. Better not to risk any damage etc. Why is the reason that its ilegal, is it technically unsafe to convert them over?

thing is, the standard power points are (were?) rated 10A.
But to ensure heavy loads (like the ones anticipated in caravans) can't exceed the power point and/or the extension cord's rating, they make the heavier cords so that they can't be plugged into a 10A socket, and the socket end of a lighter cord won't go on the caravan plug.

Unless your meter box is lockable providing an external power point to facilitate the use of
tools to gain illegal entry to the premises isn't a really good idea. Yes I know that cordless equivalents are available but doing anything to assist a break and enter isn't good.
Better to put the 15 amp power point in a garage and run the cord under the door.

Another option might be to ensure that the power inlet to the caravan etc is rated and protected for 10A rather than a 15A version. No problems if you always use less than 10A eg no air-con, heater etc :)

Graham,why is it then that on building sites you must have a 15amp lead with a 10 amp plug & caravan lead is a 15amp plug & lead to do the same job. Just a lot of Hog wire if you ask me.

I have no idea as I have nothing to do with building sites. Am only familiar with vans.
It could be that the 15amp cables are of heavier construction as in the one I have which is much heavier than the 10 amp ones I also have had for some years
HAve a read of the link posted above.

Buildings sites are exposed to a higher continuous risk of cuts and abrasions, involve larger startup currents of their machinery, and involve longer cable runs in many cases, hence volt drop and other factors are a major consideration.
Don't think about it as "15A lead" rather it should be called 2.5mm 2 Core and Earth Flexible cable or similiar, being Ordinary Duty or Heavy Duty.
Keeping it simple, there are reasons for the Rules in many cases, which are designed to cover us in almost all situations. Handling 240V is not for the backyard boys.

Not an expert, just know enough to be dangerous but on this subject I am going to ask a stupid question.
if the cord or plug or whatever is pluged into a 10 amp house power point with a safety switch than whatever the power usage is in the caravan is irrelevant.
If the caravan exceeds 10 amp usage than I would stupidly expect the safety switch to trip?
Thus no overloading even a 10 amp extension cord.
Please explain by errors in this simple logic?

Basically your error boils down to the fact that a safety switch is not a current limiting device.
It is designed to provide safety to the user by disconnecting the supply when the current flowing in the neutral conductor is not the same as that flowing in the active conductor.

OK. Please explain this.
If a power point is protected for a 10 amp load by a fuse or circuit breaker, (not a RCD device) why will that not prevent you from overloading it with a 15amp load?
Why is that any different to (for example) a stalled 2400 watt power tool, which will blow the breaker/fuse?

Domestic power outlets are generally rated to 10 amps but the circuit is generally protected by a 16 or 20 amp Circuit breaker. You could however use a 10 or even a 6 amp breaker
The circuit breaker is to protect the cable not the outlet.
A safety switch will never trip under overload thats the circuit breakers job

Firstly a 10 amp cord wont plug onto the van and a 15 amp cord wont plug into a 10 amp socket
There are rules regarding this and a standard to be followed so do it right to be safe
I also fail to see how in the comment by one poster that putting a 15 amp socket in your switchboard could lead to burglary etc. Most alarms have a backup battery and in our area we all have Energex locks on our switchboard anyway.

Australian standards suggest a 15 amp cord should be used, plugging into a 15 amp socket fro caravans. These 15 amp plugs are designed for this.
The reason is specifically so these cords are not interchangeable also the greater current will potentially develop a larger earth fault current.
A 15 amp power point should be wired directly back to the switchboard, ie; is a dedicated circuit with only one outlet attached, and so does not have any other loads attached to it
Our 10 amp outlets can have multiple power points and multiple loads.
These rules have been created for our own safety and we should follow them.
Hope this helps

You can buy double 15amp GPO's. As long as the supply cable is protected appropriately its all ok. Cheers

Hi Justin
This topic always brings out the various options which should never be mentioned in public. The cheapest (legal) way, which is all too easy is as already suggested:
"Safest way is to get a sparky to put a 15 amp socket in your outside switchboard."
We had one put on our back veranda when the house was built - and caravans were far from our minds. When moving with the job from town to town, we always had an electrician fit a 15 amp plug on its own circuit for larger power tools.
The kids want to sleep in it tonight to experience "camping". They don't need power and will enjoy the experience all the more with just torches.

Thanks for the constructive and positive replies, I decided to sleep in the van with them and we just had torches, I think a amphibian converter type devise might be the best bet as then we can use the van elsewhere, that link someone posted is just the wholesalers though, I couldnt find much retail, anyone got any links or an ebay link or something, couldnt find much on there. Gas was turned off too, good thinking! This would have to be one of the most helpful and knowledgeable boards Ive ever seen! Ive bought tyres, caravans and received such good advice over the years, thanks for everyone contributing to a top class web site!

Hi Justin,
I bought one from the Caravans Plus website:
http://www.caravansplus.com.au/catalog/product_info.php?products_id=8993
The one in the
pic is the same as
mine and works
well at
home. Also, useful if you go somewhere else and you need to plug in, as you can take it with you.
I noticed on the Amp Fibian website that the design has now changed, so not sure of the price of the new one.
I paid in excess of $200 for an Electrician to install a 15amp plug at
home, then bought the Amp Fibian. Should have just bought the AF. Have fun, Alan

Hi Guys
I am new to caravaning and have really enjoyed looking through your posts, especially on this controversial issue.
I was wondering however if someone could be kind enough to help me get my head around the wiring on my recently purchased caravan/4x4?
The vehicle is a GQ Patrol, it has a dual battery system (switch for charging on the dash), on the rear bumper there is an Anderson plug, a seven pin flat plug and a seven pin round plug.
The seven pin round plug makes the tail lights/blinkers work on the caravan.
On the caravan there is a 15 amp input (as standard by the sounds of it) and the seven pin round cable and plug (as previously described).
The van has a "Breakaway Systems" box (which is showing charged), off this there are two wires that have round terminals connected to nothing (I am assuming this is where a battery goes)?
So the question I have is how do I get the juice from the second battery to the van (when the van is parked), do I need a battery in the van?, and what are the other two plugs on my 4x4's bumper bar for?
Any help would be much appreciated.
Thanks
Joel
