RCD's inline

[SimpleSimon]

Sonebody correct me if Im wrong please.
Scenario: On a local gypsy site, the plot consists of an.outbuilding that contains shower,water heater utilitys bench and some lights. Also.supplied is a 32a comnando socket used to power the main caravan.
The main CU in the outhouse is controlled by a 30mA main switch RCD.
From the comnando.socket a 6mm armoured flex runs from the commando plug straight into the caravans owm CU. Inside the caravan CU it also has its own RCD main switch 30mA. Si two RCD's inline.
The problem is that somewhere there is a fault that will trip either the RCD in the caravan or the RCD in the outhouse,or both.
Now the RCD only trips randomly and not related to the usage of anything, Ive never seen in trip in the three/four times ive been there. Today it has tripped and they cant swutch it back on (this is all over phone today). Ive put it down to a leak as the weather round our way is awful and previous times its only tripped whenever its rained.
So when they both trip one can be swuitched on straight away but one wont come on for a few hours. It always swaps over either one or the other, ciould anyone tell me why it takes time to come back on?

So if its tripping both RCDs the problem must be coming from inside the caravan right? Im trying to tell the tennants this but they say they think its from the commando socket. Im trying to tell them that if it was the socket the RCD in the caravan wouldnt trip, I am right in saying this?
Also just been on the phone to the guy RCD in outhouse keeps tripping and stays off. So i tell him to unplug the caravan from the comnando socket and hey presto the RCD comes back on, proof that its not the socket right?!!
I just need you guys to tell me whether what ive said is right ir wrong as im gettung paranoid. If the problem was on the supply cable to the caravan, it wouldnt trip the inside RCD, only the first one right??
Thanks for reading this long long start.

The CEE socket must be protected by a RCD characteristics 415.1.1 as per regulation 708.553.1.13, so in this case an S type one can not be used

Not allowed in the caravan? FFS why not?
I might get someone round to fix a fault that might be in my house, but not let them in the kitchen.

GUYS PLEASE TAKE NOTE A Lady was recently prosecuted for having made derogitory remarks about the traveling community on her facebook and as this is a PUBLIC OPEN Forum Id prefer that this forum stayts as it is ie Self goverened Im not a MOD but just saying what Ive seen in the papers

When I find one that isn't a thieving ******* then I will change my opinion of them. However over the last 25 years it's yet to happen. Until then it's big broad bush I'll use to tar them with.

Think the point was not relevant to this forum and could cause problems forcing the forum to adopt measures it's so far avoided. Seems fair enough.

Mogga has made a valid point, it almost seems like racism remarks when talking about a certain group of people and let's not forget it is an open forum.

This is one of those times where we have to keep our own opinions to ourselves. Trust me I've had my own runnings with travellers, my sister married one! We never got on from day one because he's a tool, not because of he's up bringing, because he personally is a tool. Other members of his family are grate but even they don't like him.

Damn there goes my only bit of play!
I went and had a look today,crawled underneath and saw a junction box that some twonk has used outside to connect the masserator to a plug top, the only problem is that there's no.signs of obvious damage or water residue and IR the lead and it was fine. But its the inly obvious thing. Told her that next time this happens unplug it and put the RCD back first.
She also said RCD in outhouse (first from.CU) when it trips you cant reset it immediately but the one in the caravan you can. Sounds like it could be packing up?

Could be a fault that's manifesting itself when it gets hot then clears when cooled down...
fault finding time, you'll need access
