Just wondering if i am doing things right here,i have fitted 4 double sockets and one single in my coach (doubles as i had them spare at home) i have checked the sockets and these are wired correctly and tested with my plug in tester.
The rcd works fine and trips as it should so the power works fine.
My last double socket is situated so as it can receive either one of my inverters (a durite 500 watt pure sine wave and a 1500 watt pure sine wave inverter) obviously one will only be used at a time however they will both be plugged into the last double socket on the circuit and switched on when needed.The cable used is going to be 35mm2 fused cable to another busbar and then to the batteries.
Does this look ok to you guys??

I do like to ask opinions as i am cautious by nature:D

Just a thought.
Why would you want to connect your inverted 240volt to your main 240 ring main?

I find having the inverter fully installed. I just fun direct from it on an extentions lead
Safety first
As the two are never connected
Your proposed rout can cause an explosion. Should your inverter be live and the main be pluged in to EHU

Advise. ..... Do Not do it
Use an extentions lead for inverted power

As i dont use hook up as we dont like sites i rely solely on my panals and durite battery 24/12 volt charger.The inverter is to supply my sockets for when i am not on hookup which should be all the time:dance:
However if i want to hook up then i only need to unplug the inverter sockets and am then ready to go:dog:

NO.

Are you intending to fit a plug to the output of your inverters to plug in to the last socket?
 

coolasluck

Yes,in effect a lead with a plug on each end from the inverter side to the socket side that plugs into the mains.

NOT A GOOD IDEA AND DANGEROUS. What if somebody unplugged from your socket and touched the "live" inverter fed plug pins??????

You mention RCD so what else do you have fitted, do you have a fusebox? If you do and you have a normal hook up point then you could feed that from your inverter.

Sorry but as a member of the Institute of Electrical Engineers as well as a fully qualified Electrical Installation Inspector I have to say plug on both ends is an absolute no-no! Please don't do it! I'm sure you wouldn't have just left a couple of bare wires from your inverter...? Well that's effectively what you have done. You need some form of changeover system so there's no chance of mains v inverter if you want it on the same circuit.

Hi shortcircuit thanks for your response,yes i do have a fusebox with rcd,this all works and is fine on hook up.
I get your point and had not thought of that scenario,the inverters were to be permanently plugged into the switched sockets and switched on along with the inverter only when needed.I do not intend on using sites for the hook up so wanted the sockets purely for inverter use only.The inverter(s) were not to be left on all the time as some people do but only when needed.I did not think you could feed the box from your inverter?
 

coolasluck

ok so the best way to go then is to plug into the inverter and then run a length of cable from the inverters plug to the fusebox and to then hardwire it in to the box.It does make sense as then both inputs are going through the rcd e.t.c
Thats more damn cable i am going to have to buy then:(


Is there any diagrams online that are worth looking at?

Incidentaly the reason i have asked the question is because i have yet to wire up the inverter which is a job i need to do next.

What is the cost of cable. ? When safety is involved. Just remember it is ok you knowing what you have done. What about when you are no longer here. . Is it pull the ladder up I am ok ? Or should you be working to a standard that is there to protect not just you your wife family. But others. Who may be unfortunate to end up with your work

An old saying a little knowledge is dangerous springs to my Mind !,,,

AS OTHERS HAVE SAID. MORE ELEQUENTLY THAN I JUST DONOT DOIT. PLEASE

One more note DONOT wire two or more inverters together. It's another NO NO. Health and Safety
If unsure. Get a professional to do it.
You could blow up your motor home. Set fire to it. Killing your self and any other occupants.
Do not mess with electricity gas if your not qualified to do so
It just is not worth the risk

Hi Kev,

Google for an auto changeover switch. It might be what you need to ensure no accidents.

There is a member on Motorhomefacts who did something similar but the thread is 77 pages long and if you are not a member then the photos will be hidden. He mostly showed the work in photos.

Conversely if you fitted a blue 16 amp socket on the supply from your inverter and plugged it in to your hookup plug then you are safe. If you ever get a mains supply, you would have to remove the feed from the inverter to fit the mains supply. Bingo, job done.

I think that's wrong its should be 16 amp socket on supply from inverter and a plug on the van hook up.
 

Fazerloz

Must be an age thing its easy to get confused boss, :cheers:

Not entirely sure what you want to do, but if I understand you correctly can you not just put a 16A commando type socket (as used for EHU) on the output of the hard wired inverter and plug that into the EHU point on the outside of the van, that way the inverter output and mains supply can never be connected together at the same time. Not pretty but just an idea.

Worth mentioning that if you do this, the male pins in your EHU input socket would also be live and as such a hazard should anyone touch them.
The only safe way is through a changeover switch.

Maingates way is a easy and cheap way to achieve what is required and safe.
