Electrical issue

Hi Folks,

New to the form and caravaning.
Just bought a 2000 Baily Ranger 500/5.
When I bought it privately the EHU was connected to the caravan to show all electrics and appliances were working.
When I got home I connected the EHU and everything worked. Seen online you need to test the RCB.
I pressed the test button on the RCB and it tripped like it should. Problem is it won't stay up when try to turn it back on.

Tried to isolate the problem like I would in the house, unplugged and switched everything off. Disconnect the EHU and turned off the MCB's
But still the RCB won't stay up.

Any ideas?

Its far from unknown for an RCD to fail. Unless you have the equipment and experience to do do the necessary checks for correct operation, I do advise you seek professional help.

Some circuit breaker switches have to be pushed up and held in place for a second or two before the breaker resets.
Worth a try before you get an electrician out.

Most annoying problem!
Ok, can you plug into a neighbours mains supply?Or try an alternative socket in the house.
Turn off all MCBs.
Try resetting RCD as described by Roger.
Are you sure All appliances are switched off including hot water heater and heating?
Are you using your own EHU cable for the first time? It is not unknown for the odd one to be incorrectly wired ,check it.
Changing an RCD is pretty easy but if you are uncertain get a spark to look at it.

Once you sort it please let us know. Solutions to these problems help everyone else on the Forum.

Actually changing the RCD (or an MCB) is not that easy. Many manufacturers (Bailey included) use an insulated busbar system which means unless you fit an identical RCD or MCB the connections may not line up and then you have a problem. We had the RCD fail on our 2010 Pegasus 462 about 6 years ago. I got a Schneider (formerly MEM) replacement that was identical size - except or the connections. The only solution was to replace the busbars with with suitably rated flex (which I had in stock) - and note FLEX as solid wire can break due to vibration.

Perhaps I should have qualified “easy. “Four years ago I took my RCD to a city Electric shop. The guy found me an identical one I had no problems fitting it .I take the point they are not all the same. Except Prima Leisure will cost considerably more!

I had a similar issue on a previous van. Turned everything off connected the EHU then one by one turned everything on turns out it was the RCD for the heater on electric side that tripped .
Fairly simple to replace. Was glad to be honest thought it was going to be a heating element replacement.

Not saying this is your issue but looks to me a failed RCD . Fairly common on older vans.. :unsure:

GAS ....

I would do the checks you have done first before condemning the RCD

It's very unlikely that any of us can be 100% certain of a particular fault just based on posted information. We may have some suggestions, but for both gas and electrical issues if there is a problem that goes deeper than checking if things are turned on, then you should only attempt repairs in a touring or self propelled motor caravan if you own it, and it's not lent or hired to anyone else. That is the law .

If it requires any sort of intervention beyond the user controls, for safety you should refer the issue to a competent fitter.

To be honest I never check the earth leakage breaker, to me it's just wearing out the mechanical element of the breaker.

And really you should test both IMO.

It is checked yearly by the service man.
As with most things that are standing by such as a pressure switch you can't always rely on them working when needed.

Disconnect van from external electrical supply (EHU),then try to resei RCD.
then reconnect to EHU.
If that does'nt work then mechanical latch in RCD is faulty.Changeout RCD for a new one.
