  1. Easier, do the maths, and you will find that it has to be quite a bit off level to make any difference, especially when you consider the accuracy of the gauge in the first place. 3-4" will make very little difference.
  2. When we moved recently, we asked our new neighbours about parking our motorhome out at the front and nobody was in the least bothered. However while there is a parking space for it which is out of the way for us, it advertises when we go away, so its kept in storage.
  3. Don't understand what the problem is, there's never any ice on the windscreen when I drive out of the garage.
  4. Me neither, especially as almost all appliances in use in the UK are certified for use across Europe. I think its down to a little knowledge. Just going to post and LiF beat me to it.
  5. A fuse does work anywhere in a circuit. Its job is not to prevent a short circuit to earth- you have an RCD for that, but to prevent too much current passing through the circuit. Quite, but as I pointed out above, a fuse is there to protect against too great a current flow. Cartridges fused do not blow straight away anyway, they are quite slow, and thus a far higher current will flow for a time, as they will for an MCB.
  6. You've just said your caravan has a double pole MCB which is essentially a double pole fuse, and one which is much more responsive than the fuse in the plug. Common sense should tell you that this MCB will trip in the situation you describe above whatever the polarity if the RCD hasn't already tripped as has been stated above.
  7. I cannot imagine any domestic electronic equipment where it matters in the slightest. Mains electricity is alternating current. Noooo! A fuse will work just the same anywhere in a circuit. This topic has had me in stitches. It is so funny. As for carrying 6 leads to have all permutations, that is simply classic. Quite frankly, with most modern caravans reverse polarity matters not a jot. While you are panicking about reverse polarity, ask yourselves the following questions first: 1. Have you tested every socket in your own house for reverse polarity. There's a fair chance you have at least one. 2. How modern is your house wiring? Has it got a modern consumer unit with RCDs covering all the circuits. If not why all the angst about your caravan. Surely your home needs to be safe too. 3. How many examples of people being electrocuted on caravan sites have you ever heard of? 4. Have you checked the consumer unit on your caravan. Does it have an RCD, and does it have double pole MCBs. 5. Is your caravan a continental model? 6. Have you considered that continental models electrical systems are designed for reverse polarity situations. 7. Have you considered that modern UK caravans are designed to be taken abroad and thus (6) also applies.
  8. I think you will find Norway has its own unique electricity distribution system. It would be your polarity indicator that could not cope with it rather than there being no earth. See below: Seeing most caravan sockets have no switches, it doesn't matter whether they are single or double pole. The only precaution you need for reverse polarity is to unplug something if you are going to take it apart or stick a knife into a part which may be live.
  9. I changed mine at 6 months old because it was so badly built. I doubt it would have survived for much longer.
  10. If its an Elddis, I would suggest a large selection box of screws and plenty of glue. A selection of acrow props are essential to keep the roof up and the cupboards on the wall.
  11. While heating may do something for condensation, it will do absolutely nothing for the dreaded damp. The latter is caused by water getting in from the outside and getting into the structure of a van. As nearly every van has a waterproof lining, little or none of the water ingress can escape inside the van where any heating can deal with it.
  12. That's the thickness of meter tails, not earth bonding. 10mm2 is the normal size I believe. Interesting, had a new boiler fitted today and specifically asked if water/gas pipes needed bonding, and the answer was no, because they are all bonded to the boiler frame already.
  13. True, but he should have put an advisory note on the certificate. There are conditions as to when and where you can add a spur. Not that simple! However, caravans are wired differently to domestic house wiring for the sockets.
  14. Potential energy maybe but energy, nope. A complete contradiction. Potential energy IS energy. Try illuminating an LED by standing it at the side of a magnet, that would be a simple demo to prove whether a magnet has energy or not (it doesnt). No this is not a simple demo to prove whether a magnet has energy or not, frankly it proves nothing. I could suggest you stand your LED next to a battery, you still will not prove whether the battery is charged or fully discharged because nothing will happen either way.
  15. Permanent magnets do have potential energy, stored in their magnetic field. Gravity does not generate energy, it simply converts it from potential energy to kinetic energy. Thus water in a reservoir above a hydro electric plant has potential energy. Potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Kinetic energy is the energy which a body possesses by virtue of being in motion.
