Private feedback for this item:

Thank you for sending me the order so quickly
and it was great to have the hand-out about how to test European hook-ups
and the various possible solutions.
This is great to have for a novice abroad like me. Thanks. May'15
Thanks Jonathan, in France and Italy we wondered why we kept blowing the RCD on hook ups. Used your tester which showed an issue so used your Reverser and bingo IT WORKS! Cracking job, thanks. Sep'18

Because of the problem of encountering so-called 'reverse-polarity' at some European campsites, it is vital you test for this on arrival, and correct as necessary. The simplest way to do this for motorhome or caravan users, is to connect your hook-up cable, and then plug into any socket inside the van, a tester that will indicate live/neutral reversal—from £9.99. If required, you can then simply insert this reversing-adapter on the source end of your mains cable, and thence into the power-point.
The great advantage of this method for counteracting 'polarity-reversal' is that it works on your main cable rather than in a Euro-adapter, which of course isn't now required on many Continental campsites, as the majority are adopting the standard blue IEC60309 (BS4343) that we use.
Tenters too, can use this correcting-cable, and test for reversal directly on the trailing socket.

Why this situation can occur on the Continent:
In UK, switching is only done on the live line, and because our plugs & sockets are always connected the same, both switches and circuit-breakers (including RCDs) render cables & devices completely off, and safe.
In Europe, generally, switching is done simultaneously on both the live AND neutral lines; and because of this safer practice, it is not unusual to find live or neutral randomly connected to live. This is perfectly fine and safe, but does cause issues for UK visitors.
Firstly, many of our switches and RCDs, including some in motorhomes/caravans are single-pole, (meaning that they ONLY disconnect the live—or at least the expected live), but where the lines are reversed, they only pointlessly disconnect the neutral, leaving live power running past the switch/RCD, through any following cable and into all connected devices…even after any single-pole

RCD has 'tripped'!
Using a 'correcting' adapter like this will channel the reversed-live from the power hook-up into the proper live line of both switches and RCDs.
Another reason why getting your live/neutrals round the right way might be important, is that some devices simply won't work properly, or worse, may be damaged; (notably some computers, microwaves, VCRs, DVDs).

"Voltage on most sites is usually 220v nominal but can be less. Most UK 240v appliances are rated at 220v - 240v and usually work satisfactorily. You will need the mains lead that you use in the UK, as many sites have the European standard connectors (CEE17) found on The Club's own sites and which your UK 3-pin connector will fit. On some sites, you may need a continental 2-pin adaptor, available from UK caravan accessory shops.
Caravanners can encounter the problem known as reversed polarity. This is where the site supply's 'live' line connects to the caravan's 'neutral' and vice versa and is due to different standards of plug and socket wiring that exist in other countries. We therefore recommend checking the polarity immediately on connection using a polarity tester, also available from caravan accessory shops, before you leave.
The caravan mains electrical installation should not be used whilst a reversed polarity situation exists. Ask the site manager if you can use an alternative socket or bollard, as the problem may be restricted to that particular socket only. Frequent travellers to the continent who are electrically competent often make themselves up an adaptor, clearly marked "reversed polarity" with the live and neutral wires reversed. This can be tried in place of the standard connector, to see if the electricity supply then reverts to 'normal'." ~[from 'First time abroad with your caravan or motor caravan' by the The Caravan Club (UK)]
