All the best!
We use the intermediate switch as a protection right at the campsite connection, so the route is secured between camping and caravans.
The caravan has its own fault circuit breaker. But should the connection or the like by tripping be demolished and any wires are frayed, it is dear to me, that the route is also secured.
The intermediate switch was in the wet grass, it was raining, no problem, he remained tight :)
