Hi There

Booked into a powered site in June, and when I booked I was told I would have to bring a 15 amp lead to use the electricity. I didn't initially want a powered site, but needed two sites next to each other, and the non powered sites were mostly taken with none left that were next to each other.

I'm a bit confused as to what is the point of having this sort of powered site, if you can't use a normal lead. It's going to cost much more to pay for a lead than the $2 extra a day for power. My husband thinks I will be able to use plugs with two prongs only as it is only the earth that is different in a 15 amp lead. ie. I could charge my mobile phone.

I'm just in a tent, but if you were in a caravan I'd imagine you'd need a 15 amp extension lead as well as a normal 10 amp lead to to connect power to your caravan. I just have never come across this 15 amp thing before.

Thanks

It is the requirement of a powered site that it has a 15 amp socket. The Aust Standards require it. The standard is adopted into law in each state and territory by the relevant legislation.

There are exceptions but you'd need someone who knows the legislation to give you advice on it.

In the mean time a 15 amp lead doesn't cost much and you can plug a 10 amp socket directly into it.

Don't cut the earth pin off under any circumstances. Someone could end up getting electrocuted.

Hi VioletMay

Your husband was right (but aren't they always).

As you didn't need a powered site - just don't use the power and no need for a lead.

I'm no sparky but at home we have a number of 15 amp outlets which are used for welders, pressure cleaners etc. Also our standby genset has only 15amp outlets

A normal 10amp male plug goes into a 15 amp female socket, we do it regularly.

The other way round is not possible, the idea is to make sure that if you're drawing a heavy current you have the lead that is appropriate.

If you're only plugging in a battery charger, light or anything else with a normal 10amp plug you have no problem

Qualified electritians may wish to add/correct

The ten amp lead is the smaller of the two and will fit a fifteen amp socket. They provide 15amp fuse for trailers that use a lot of power. Your on board fuses will provide protection.

May they want to rent u a lead?

Beware of the "Power Plug Police", they do spot checks and if you don't have a 15 amp plugged in they will disconnect the power immediately and tell you to get the right plug.

Park owners are probably under orders to ensure rule not broken and they will probably bring it to your attention .
Happened at Pottsville year before last and the van owner was not impressed with hot beer etc after the "PPP" pulled the plug on him.

does anyone know off the top of their head which regulations were broken, inparticular the clause number? IT would be interesting to see if this is enforcable, especially with people running sleep apnea machines etc and maybe not having a 15A lead available.

Emmmm... it isn't for me either but some people are making a lot of money by forcing others to pay for, what is effectively, legislation! Wonder how we'd feel if we had to pay to find out what others laws said:

"You're nicked sonny!" - "But officer I didn't know that was the law!" - "Well you should have bought a copy of the 1987 Jaywalking Act then shouldn't you sunshine".

Do a PDF search on AS3000 for caravan.

Gday,
15 amp is very common, especially where in the majority of cases more than one appliance is going to be run off that lead. Eg caravans.
Your "standard" 10 amp lead will plug into their 15 amp socket and to most appliances but not a caracan socket if its set up properly.
At a guess they are probably sick of people using 10 amp leads with a 15 amp females plugged into their socket and tripping curcuit breakers and fuses all hours of the night so they just warn everyone before they arrive. (good call probably)
Do your self a favour and buy a 15 amp lead, they really arent expensive.
If you only want to carry one lead, make it a 15 amp. And Im not suggesting for a minute to cut off the 15 amp male and and replace it with a 10 amp male so you can also use it from a 10 amp outlet when you are absolutely sure your not going to be drawing more than 10 amps, like running a light or something. And before I get crusified buy the people who do NOTHING not by the book, I say again Im not saying do this!

Cheers

If the load trips circuit breakers and fuses on the supply side, then the load will be in excess of 15A, which means the 15A extension cord will be overloaded as well.

The current carrying capacity of the lead will not alter how the protection devices trip from the supply. I could use an extension cord that is rated to 32A (with 15A plug and socket), however if the load is 20A, it will still trip the 15A supply protection devices.

Regards,
Dion.

If the 10 amp lead was old and dodgy and got hot because it was overloaded wouldnt that trip the earth leakage? And break electrical codes which would void insurance?

If you don't need the powered site for anything else, just plug the phone charger into the outlet. They'd be hard pressed to be pedantic about a 15 amp lead not being used in case someone had done the wrong thing and connected it to a caravan. Not uncommon to see phones on charge on power outlets at CPs. Just don't leave the area in case someone takes a fancy to your phone.

Caravan parks supply 15A outlets because most peopl in an appliance filled rig will pull more power than 10A Eg. aircon, lights, battery charger, fridge,popcorn maker? etc. then turn the microwave on high. POP' goes the breaker on the pole.
When supplying 15A power to caravan sites it is a requirement to inform people that the outlets are 15A for duty of care purposes,which would clearly be stated in their insurance contract. The reason is for example; when a 10A circuit is supplied, 10A rated power leads are the minimum as it must be capable of carrying 10A worth of power without any Undesired affects. So the same applies with 15A outlets so to ensure that if anything pulls to much power......the 15A breaker at the pole will trip , turning off the power before anything else can happen.

Bunnings sell 15A caravan leads, they have moulded plugs on both ends and a water splash lip to reduce the likelyhood of water shorting the connection on the camper. Note: All campers now produced should come with 15A inlet and wiring to an RCD protected breaker before anything else on the camper or van is supplied with power.

Try cutting many (most?) of the IEC moulded leads supplied with much domestic equipment (computers especially!) in half and see if they are capable of carrying 10A.

I chopped the socket off one yesterday and I would rate the cores at about 7/02 - should be good for 3A - maybe... on cooler days!

There are exceptions when the lead is hardwired to the appliance or similar situations Mike, and I was trying to keep it simple for the non electricians out there so I have left the ins and outs of Appliance leads and lengths(voltage drop) out of the situation.

You are right about small conductor sizes in some IEC type 1.5m appliance leads though mate. Yet they are not and Extension lead that can be plugged into an ever expandable loadcentre/powerboards etc.

Mmmmmmm

The power outlet at a caravan park is rated at 15 amps. It is protected from excessive current draw by a 15 amp circuit breaker or similar device. The breaker should shut off power if the current exceeds 15 amps. Thereby protecting the 15 amp lead from a fire or meltdown if too many appliances or a short develops.

Plugging in an extension lead with a lesser current rating (i.e. the 10 amp extension lead) into the 15 amp outlet means you can draw MORE than 10 amps from the lead. The circuit breaker will not trip until it reaches 15 amps. Drawing in excess of 10 amps for a resonable period will usually result in a fire as a minimum.

Using a 3 pin plug with the earth cut off is pure suicide.

Hope this helps in your evaluation.

It is a silly rule and only provides protection for a 15 amp supply circuit in a Caravan!

Imagine this scenario, which is not beyond the possibility from the adverage camper.

You do as required and plug in a 15 amp lead to the power box and run the lead to your Camper Trailer, or Tent.
Now, inside you need to run more than one appliance at a time, so you connect an el cheapo power distribution board to the lead. The power distribution board or course has a combined (total) rating of 10 amps maximum, but how is this controlled?.........IT'S NOT.

Because you can now draw a maximum of 15 amps before the circuit breaker in the power box will trip, but the rating of the distribution board and its short lead is 10 amps, you may get a result of overheating and "meltdown", potentially causing a fire before the ELCB protection trips out.

This is not an issue for the majority of devices one is likely to plug in, but consider the "must have" Camper who runs an electric kettle, breadmaker and god knows what else, at the same time. (They may even have an electric blanket on the same circuit)

If people must use a power distribution board, ensure it has its own overload protection. (i.e. it will trip out if you exceed the maximum amp rating of 10 amps, regardless of what and how many devices you have connected)

Such boards will have an overload reset button on them.

Hi sandman,

I never seen a powerboard without an overload protection system (button for reset).....do they exist? I would have thought they wouldn't be able to be sold in AU due to not meeting certain standards, similar to the old piggy-back plugs.

They do exist.

The builders power boards have an RCD with a trip button.

However, what I understand (and no, I'm not a sparky), when dealing with power to a tent or CT , it must go through a RCD device , and , it CANT be via a connector , eg , extension lead , plugged into a distribution box , it MUST be one continious lead , eg a Builder Block with a long lead.

When using my CT on power I use a 15amp Power lead into a Builders Block , technically , NOT legal as I understand it , but , it has never been questioned by a Cvan park.

Are you saying that there is no overload protection associated either within the RCD module itself or as part of the powerboard?

There IS that protection in a Builders Powerboard. It has a fuse (like a house fuse) , and a test/trip button.

I have a powerboard that does have an overload protection system in it (and have used it with the CT), but , I wouldn't trust my life to it. I found it tripped at the slightest thing (a good thing yes, but quite impracticle).

Folks,

I'm not referring to a "Builders Power-board".

I'm talking about your average household power distribution board obtainable from any Hardware shop, Dick Smiths, or "Cheap as Chips" outlet. (Usually white, plastic, with four to six outlets and a 1 metre power cord). There is no regulation to say that these MUST have overload protection and none that I have seen have RCD (ELCB) protection either. This is the one "Auntie Joyce" or "Uncle Ian" is most likely to take along camping with them.

And because they are inside a tent, camper, etc., no "Power Cord Police" is going to know what is on the end of the valid 15 amp cord and disconnect it. You are complying with the requirements as far as they can observe.

Remember, I'm giving a scenario of an average "non sparky" type person who has only been advised they must have a 15 amp cord to plug in to the Park supply.
