Van keeps tripping house electrics.

[Wh05apk]

We have a 2018 le voyageur, in the week whilst plugged in overnight, it tripped the house electrics, I assumed it was the charger causing it as nothing else was on, when reset it stayed on for a couple of minutes before tripping again, during that time the charger only seemed to be supplying about 2a, which seems very low?
No heating was on, the fridge turned off, as far as I know nothing is plugged in, the only other mains item is the roof air conditioning, so will try to isolate that in case.
Trying to get sorted as we are due to hi away on Friday.....

As with most things electrical I would start at the first connection. Check the lead, then switch off everything in the van and turn on one circuit at a time.

 

[Wh05apk]

Does only 1-2a sound right for the charger?

 

[mike mcglynn]

Try another hook up lead .

 

[sonny]

Plug in the supply but not the van if it blows then probably the lead.

I know it sounds a bit too detailed and over the top, but can you say what exactly you mean by 'tripped the electrics'? There are two completely different faults, and it helps to distinguish between the two.

There is an RCD, which has a 'test' button on it, and trips on leakage faults. There are MCBs, which do not have a test button, and trip on overcurrent faults. Which one of those two was it that tripped?

  Charging at 18 amps it would take less than 1 amp from the mains.

I had the same problem recently. Changed the hookup lead which I can only describe as being "waterlogged"!

That's 1-2 amp on the internal meter, so 12v , a max of about 20w

The MCB on the fuseboard

That was my initial thought, everything appears dry though, changed the 3 pin connector in case that was damp.

The MCB on the fuseboard

How big is the MCB? And is there other things on it?

 

[Wh05apk]

Not sure on size, use a different circuit and still blowing, so sure it is the van, causing it, initially overnight when not much using power, no large draw in the van.

 

[Richard n Ann]

Is the MCB on an RCD too? . If so it's tripping on over current not earth fault. If not it could be either. A 500v insulation tester would be handy at this point ?

You can narrow down the fault location.
Does it trip when the hookup cable is connected to the house but not plugged into the MH?
Next, switch off all the MH breakers, and plug in again. If it trips, the fault is between the inlet plug and the switch box.
If not, try all the breakers, one by one, until you find the one that trips the house electrics.

That's exactly what I have done, but switched off the Aircon before doing so, and now appears to be working, will give it 20 minutes and try switching the Aircon back on, hopefully that will trip it and confirm that's the problem, if not, plan b......

If on absorption or maintained charge phase that would be about right.

Showing as about 80%soc so sounds ok then.

 

[Wh05apk]

Tried the Aircon and all ok, so can only assume either something failing, or damp?
Hopefully now going away after Christmas now.

Thanks for all your help.

Exactly what I have just done and it is the fridge breaker that is the problem.

Not so good, we can make do without the Aircon, but not the fridge, hope you get it resolved.

Do you have mains heating? When our Truma mains heating elements blew it kept blowing the rcd when we plugged the EHU lead in and turned the heater on.

We do, but it was turned off, now all seems to be working fine.

We've had a lot of rain recently. Remove your fridge vents and check nothing is wet inside. Maybe a good idea to put a fan heater blowing into the lower vent to dry the area out, if any moisture found.

 

[autorouter]

Not sure on size,

An MCB will always have its amp rating written on it. With a letter in front to indicate how 'sensitive' it is to the overcurrent. Examples: 'B6' is a 6 amp MCB, 'C32' is a 32 amp ring main MCB.

If it has '30mA' written on it, it's an RCD or RCBO

Most common causes of red tripping on household appliances are heaters not expensive but can be a pain to remove if you can isolate the fridge heater ie disconnect the feed wires then you have the fault can be caused by moisture in the heater when I was working used to remove the earth from the supply switch on for a while reconnect and usually moisture had dried out but don't touch anything while the earth is not connected

 

[Bigjohneaton]

Should have been rcd not red
