I need to put in an extra sockets in a static caravan. The easiest route is to run from an existing socket in the ring, through the floor, under the caravan and then up to the new socket position. Could anyone tell me whether the run under the caravan needs to be in SWA or can I use rubber flex as the run will effectively be under the floor - though the van is on a hill and one end is around 4ft off the floor and therefor accessable from outside by bending or by a dwarf? (will in done in 2.5mm)
Thanks
