Electrics tripping to static caravan from outside power supply
Electric tripping at outside small stand alone power point between main electric house and caravan small power point 2 metres away from caravan. It never trips in caravan the cable at outside is looped out of box.
We only have to put on a couple of oil heaters for this to happen. We never use the outside lights as this does trip it out we have just purchased this van 2nd hand in summer.
Could it be dampness to outside lights, this has really just started to happen.
Any advice, in our last caravan it was a fault in small box outside.
