    Evening everyone, after some answers please about the basics when it comes to understanding 10 / 15 / 20 /amp EHU.(not sure if i wrote correct) Reading some posts about decent campsites they state the EHU rating.

    please can someone explain the meaning of the different ratings and how it would effect me if i got something wrong and what is the basic i need to know

    Many Thanks

    Mark

    Hi Mark you cant get anything wrong
    it just means the higher the number the more electrical things you can have on at the same time without tripping it

    The higher the amp figure the more electrical appliances you can run in your van when on site.
    You need to work out the current rating for what you have such as tv, hairdryer, microwave etc. THen you will know what you can use on an EHU. Generally in this country you can expect 10-16 amps. Howevre on the continent as little as 3 amps.
    I was on a site in Holland and in order to use the electric kettle I had to switch the fridge off.
    I was on the Abbey Wood site some years ago in October and the trips kept blowing. This was due to a group of tuggers all in the same all singing and dancin vans with blown hair electric heating,girlies listening to stereo systems and drying their hair with a tv on!!

    It's reasonably simple AMPS x VOLTS = WATTS.

    So if you were on a common 6A feed you could run up to 6 x 240 = 1440W or 1.4kW.

    UK domestic sockets are rated at 13A. So 13 x 240 = 3120. The biggest electric gadget you plug in is 3kW.

    If you plug your 3kW kettle into your 6A supply a circuit breaker will pop and you will have to ask the site manager to reset it. No harm will be done apart to your pride.

    Ah right it all becomes clear, cheers guys.

    Thats good news, so glad i cant blow things up or damage the van.
    With the EHU connection lead this should be capable of taking all levels of power then in the uk or abroad?
    Mark.

    Reading the above its not the cable i need to worry about its the overload on the breakers, with yer now

    just to confuse matters.....if the site is very busy dont expect to get 16a from a 16a supply.:Eek!:
    16a is the MAX it can supply.
    there is only so much to go round and if it gets overloaded the MAIN site breaker will trip.

    ask anyone who was at The dirty duck at Grantham for the new years meet

    So in theory Pappajohn, 16A should kick out enough juice for 3.8Kw item.

    But dont hold your breath, ha
