EHU sometimes trips either shore ore house units or van control units. (16 Viewers)

[Graham Deans]

Firstly, I am useless with electricity. On recent Europe trips I cannot get power to the van as something trips, I had this looked at by a van electrical specialist (not impressed), and then by my friendly local electrician who I have found really reliable. After exhaustive checks and a few socket replacements it seemed to be ok. I have just tried it before I go away and no power, house consumer unit tripped out. Unplugged and repeated and all OK. Has anyone any idea what might be the problem .
Thanks Funsters.

If the van has been checked out, could it be your lead?

Is your fridge on? Is your boiler on? Is it when the charger cuts in?

If the van has been checked out, could it be your lead?

Or socket.

There's also been a heck of a lot of rain so maybe it has caused a short circuit in the EHU plug/socket if it isn't sufficiently sealed?

Could be many things, but most likely to be

• Fridge going into defrost mode and the element has got damp.
• Water heater similar thermostat faulty or leaking,
• Battery charger faulty.
• Something else that is plugged in that does not operate the whole time.
• Possibly the lead

Most of those as already suggested..

If you can. turn off everything but leave it plugged in, does the trip drop? Then plug in things one at a time leaving a hour or so between each until it does drop. Even then you cannot be absolutely sure its the last item plugged in unless you unplug everything else again and see if it drops again.

Intermittent faults are the worst to find.

Just make sure that everything that runs from the ehu is switched off in the van before you connect to the ehu. Then start to turn on your 240v items to determine when it trips. Or what causes it to trip.On some sites there is only enough power to run a fridge or charge your batteries (6 amps) anything else will cause can overload and hence a trip.
You may have to juggle what you have on.

A 2nd vote for the lead.
If it's all been checked by two separate electricians and found ok it can only be the lead.
Corroded or loose wire in either plug or possible damage, either visible or not, along the length of the lead.

I had a similar problem after fitting a socket for a microwave. When I plugged the EHU in the post breaker dropped out. After loads of checks narrowed it down to the brand new socket I had fitted. Replaced it with an old one (I knew I had one but couldn't find it!) everything was ok again.
New socket went back to B&Q for a refund.
Been perfect since.
Cheers, Dave

My experience was the big blue plastic connectors on the EHU lead and on the external power socket
I had assumed (wrongly) that they were waterproof
They filled up with water and tripped out the house and MH
The fix was easy, dry out everything and reassemble with lots of mastic sealant at cable entries and where the plastic bits join together
No more problems
Good luck
