First time with EHU - what do we need?

[EasterMum]

Hi there, we're getting a pitch with EHU for the first time - could anyone please advise what we need to take with us in order to connect to the EHU supply? I assume it's some kind of long cable that plugs into the EHU connection then into the tent, with a socket or two on the end of it?!? Is there any kind of variation in price or quality? We'll be in France if that's relevant? - I suppose we just need to remember adaptor sockets?

Thanks very much!
