member Dartman, Caravanner five red stars [Online] Posted 09 August 2012 by Dartman Quote | Report D Man...Why not carry a short length connector already wired reversed? Reversed polarity occurs on 50% of sites in my experience. Just plugging a pre-made additional short length of cable with male/female is much easier when on holiday...why get the screwdrivers out? Very simple, non of the plugs and sockets are waterproof, they are designed to plug in to a specifically designed socket so water passes by and not enter plug, the flying lead you advocate is not. The advice for EHU is one single lead, do not join leads, or have connections exposed to the weather. Therefore the the advice take a reverse polarity lead and a European type plug to cover all situations is not good, unfortunately the option regarding the French/European style plug is not really practical so in that case you have to accept the flying lead connection Post liked!
