What it means
An RCD (residual current device) trips the mains supply the instant it detects current leaking somewhere it shouldn't - often as simple as a damp connection, but sometimes a genuine appliance fault.
What to do
- Unplug any appliances you've recently plugged in and try resetting the trip.
- If it holds, reintroduce appliances one at a time to find the culprit.
- If it trips again with nothing plugged in, the fault is likely in the van's own wiring or the hook-up cable itself - get it checked.
Likely causes
- A wet or corroded hook-up connector
- A faulty appliance plugged in
- A genuine fault in the onboard wiring
Rough UK cost
Often no cost - just a wet connector to dry off. A wiring fault repair typically runs £80 - £250.
