15Amp Inlet and breaker advice please...
A camper person might know...
Got a 15A Inlet (the kind that people stick on the side of a caravan).
Bought a 15A Earth Leakage breaker.
Want to fit 1x15A socket and a double 10A socket.
The inlet is Active/Neutral/Earth
The breaker is Active and Neutral (2 connectors top - which I assume is out, and 2 at the bottom, which I assume is in).
So where does the earth go - I guess it runs to the sockets in serial. The Neutral and Active run off the breaker and to the sockets in serial.
The aim is to be able to use 15A site power in my bus, with a breaker at my end).
...electicians?...hoping not to have to call one out as I bet its a 5 minute job as its just going on a power board...no body mods needed....
Anyone know what Im on about?
Cheers

Sort of
The earth leakeage measure the active amps Vs the neutral amps.
If they are not the same then it "assumes" it is going to earth and trips out.
So earth just by passes the ELB.
So you should go from the bus 15A "plug" to your ELB then to the power points that are hooked up in parrallel. The earth just goes from your bus
"plug" to the earth socket in your power points

The earth goes direct to the outlets (not switched), and sounds like the breaker is double pole (switching both active and neutral). Go to the 15A
socket first as it is the greatest load, then the 10A. You will be exceeding the 15A the inlet is designed for, but as long as you periodically check
the lead at all plug connections for heat you will be ok. you could always run 2 X 15A inlets and 2X leads to your power source to be safer. I have
run from 1 x 15A inlet, a 300w coffee machine, 1 X 250w grinder, 1 x 1500w pie oven and 2 x 200w fridges. All these appliances were run at once from
cold (except fridge as they were always on) drawing maximum current to warm up for a about 2 hrs, then switching to genset. The cable needs to be
correctly rated and it will be fine, but the plugs and sockets can get hot. I have seen 10A plugs melt into the socket with this sort of load, so just
be cautious.
Wayne.

that makes sense. In parallel...so run 2 wires off the ELB - one to each socket - not 1 wire off the ELB to socket 1 and then from socket 1 to socket
2 (which I was calling serial). Like this...assuming Active/N/Earth comes into the inlet.

Nope, I have confused you. Connect it in parallel, but go from the breaker to the 15A outlet, then from that to the 10A outlets. Do the earth from the
inlet to the 15A outlet, then to the 10A outlet.

Your pictures are the same thing - parrallel. Just joining at different places.
Both is correct.
As long as when you put a volt meter across active and neutral you have a direct link back to 240V

Why don't you get somebody who knows what they are doing have a look at it for you.Sounds like you are not very confident.you could kill yourself or
somebody else.The outlet should be a double pole variety as used in caravans.

What Stevosky said ,if you dont know without having to think about it get a sparky ,240 is lethal,for the sake of $50 get it ticketed:beer:beer:beer
Don't argue with an idiot; people watching may not be able to tell the difference.

Just a quick word of warning coming from a licensed electrician. If you are caught doing your own wiring you could be up for a rather larger fine.
There is an Australian Standard, AS3001, that looks after the wiring of relocatable homes (caravan, tents, etc). You should be able to get it from
your local library.
Another thing to consider (don't know if they check anymore) but the caravan parks would check to see if the wiring had been tested in the caravan
before they would let you hook up to their supply.

thanks for the solid advice. What I was intending to do was ensure that I had the right parts for the job, and yes I read up on Caravan regulations to
ensure that it is correct. A friend, who is an electrician, put it together for me and all is good.
I just like to know new things, so that I at least know what I am looking at in the future
Thanks
