Tripping EHU

Hello new owner of a new t6 conversion first time away & first time plugging into the site mains & it tripped their power. The rcd inside the van doesn’t trip just the sites power point. Tried a New cable & same thing happened. Everything in the can seems to work & tested fine. Any idea on what can cause this ??
 
Have you got a large load switched on in the van when you plug in ? I'd make sure everything is off before plugging in.
 
Van*

Nothing at all plugged in

Only the fridge is on

Tried with everything off too still the same problem. All works fine until we plug into the sites power

I'm no expert, but I'd try turning fridge off.

Does it do the same in another site socket?

I did read somewhere about 'reverse polarity' possibly being an issue on sites. I'm sure there is a socket tester thing.

Un plug your EHU cable from the van & plug it into the EHU. So it’s just the cable & see if it still trips. If it does, the fault is in the cable.
 
Could have been a fault with the site's hook-up point - did you have the opportunity to try an alternative point?

Yes tried a few different ones’ & cables I think it must be wired incorrectly

Tried with it off. Going to check it’s wired properly maybe wires are touching or something

Try as above.

Your ehu lead alone, with no van.

Then try with van. But cu switched off.

Then try turning one one circuit at a time
 
Looks like water sprays right off the back wheel into it. Will put a new one and silicone it. Must be something I can put as a shield

Yeh I would be fabricating a shield of thin aluminium and glueing it in place with sikaflex.
Got any pics of inside arch ?
 
The plastic flange needs some heavy metal spreader plates - plastic and 4 bolts/screws is a recipe for disaster. Plastic always has a tendency to warp.
