Does anyone know of a previous thread, or website anywhere that gives guidelines on which electrical devices can safely be off which amp rating?.

For instance, if a hookup is 6A (or 4A, 10A and so on), which appliances can be safely run from that hookup?.

There have been dozens of threads on this subject so a search should come up with something. Just as a quick guide each amp is worth 230 watts so if you have a 6 amp supply you can use up to 1380 watts in total. All appliances are marked with their maximum wattage so its just a matter of adding up the total wattage of the appliances. Generally anything with a heating element tends to use more watts but things like chargers and lights use relatively little.

Hi, I'm in the same position. Never used an EHU before but plan to go camping in the first week of April so I bought one yesterday along with a small fan heater from Tesco. Will this be OK?

Also read on a Camping and Caravanning Club leaflet that you should have an EHU with a connecting lead of 25m...........mine only has 15m.........is this OK???

You should be ok with a 15m lead. The C&CC states 25m just to be certain that you can reach the EHU point from your tent. We have a 15m lead plus a 10m extension lead but we have never used the extension since we got it 3 years ago.

The maths for working out how many appliances you can have on at any one time is wattage divided by voltage equals ampage. So if you have a 1600 watt hardryer you divide that by 240 volts which equals 6.66 amps. The caravan and camping club sites normally have 16 amp hookup so you would be left with just over 9 amps for your other appliances but it is always best to check with a site how many amps their hookup gives. In France it can be as little as 4 amps.

I can never be bothered with the maths so as a general rule I never have on 2 things that can heat up at the same time. So I always unplug the heater if I am going to use the hairdryer. Anything that doesnt heat up uses very few amps and should be fine.
