Hi guys
When I plug the mains cable in the motorhome from the house
It trips a breaker in the house and also in the motorhome
I have tried different sockets in the house same problem

Do you have a different lead to try?

It could be a break somewhere in your lead or a loose wire in one of the plugs causing a short.

Maybe a member nearby could help and lend you one to try. Unfortunately I am nowhere near you or I would happily help.

Plug the lead into the house first without the motorhome connected. If this is good then plug in the motorhome. If the house trips then your need to check the plugs on each end of the leads. Before opening the plug make sure that the lead in DISCONNECTED from the mains. The green/ yellow wire is the earth ( big pin). The brown wire is the live and the blue is neutral phase. A quick Google will show the layout.
Personally I think that the blue and brown are wrongly connected but for a proper professional opinion an qualified electrician should be hired to fix your problem. For a lay person to perform an electric repair and should an insurance claim happen as a result, the insurance company will void the claim due to unqualified labour.

If you are certain your power lead is good, start to isolate all the AC circuits one by one. That is to say, pull the fuse/breaker on all components that receive AC mains supply. Such as fridge, sockets, inverter, battery charger etc.. If all of these components are disconnected by opening breakers or pulling fuses and your mains cable is good, you should not be pulling out your house breaker. So work back one by one until you see what is tripping it.

Use a 12v source and bulb - attach to two of the pins and bulb other end - see if lights, then try other pins to test all 3.
OR a continuity checker in a gauge?
Crossing neutral and live shouldnt really cause an issue in the circuit to cause a trip/ There must be a leak from live / neutral to earth in the cable or M/Home?

crossing live and neutral will cause a direct short in the circuit and cause the cicuit breaker to trip, a leak from live to earth will cause the elcb to trip and knock all circuits, as another poster said switch all circuits off at trip switches plug in lead and one by one turn on trips and see which one trips!

Without the lead plugged into any power supply , run the cable trough your fist and feel for any damage or nicks or bends.
Have you anything you can plug into the cable, power tool/drill to check the lead works ?
Have you rolled out all the lead before you plugged it into the EHU socket ?

Reversing live and neutral won’t necessarily trip the trip switch. Shorting them out most certainly will. You are on the right track by isolating everything in the Mh if it doesn’t trip, start introducing them back in 1 at a time. I had an issue with fridge in 230 when I came back from holidays over Xmas. Damp in 230 volt element. Solution was to run it on 12 volt ( both elements in very close proximity to each other. Left it for half an hour to give it a chance to warm up and dry out the 230 element and bobs your uncle. Perfect since

The fact the trip is falling in the house and the van tells me the problem lies after the hook up lead and in the van itself.
If the lead had a leak to earth then the house would fall but not necessarily the van.
Both trips going down says there is a leak somewhere in the van (ie. After the lead) and Needs investigating, Daffysparks is right.... eliminate circuits and bring in each till the RCD drops out and investigate that one.

Do you have anything connected in the MH when trying to plug it in? Make sure everything is off, including direct sockets, etc... I would even turn off the battery charger if you have one.

Both breakers tripping could mean either a short or an load that exceeds the rating of your breakers, it's a process of elimination.

If you have a multimeter it should be handy enough to test the cable.

I'm in Cork too, so let me know if you need a hand :)

I'm still a little unclear as to what happens with the cable plugged just into the house and not connected to the van. Does that cause the House breaker to go?

If you have a spare female end kicking about wire a normal 13 amp socket to it and use the lead like an extension lead plugged into the house and put a drill or a grinder on the other end , If it works fine its not your house nor the lead the fault will be inside the van.

So it turns out there was a short in one of the cables going to a socket rewired and good to go 😁
