[quote author=Beanzy link=1108287874/0#8 date=1108329112]Some sites work off 240v, but they're always the smaller ones with loads of subbies and it's all on an iso tranny backed up by an internal trip, or else RCD. Bigger sites seem to provide and test it all up to the outlet so they just stick to 110v.
That was a big factor for me when I bought the battery kit. Didn't want to have to lug trannies about, or second guess what would be provided on-site. Just missing a kettle now, will have to use one plugged into the car ciggy lighter. Then again the amount of tea I drink in a day I'll never get home due to flat batteries.

if it is true that a 240V kettle can run on 110V then you could just carry several different mains leads and select the right one based on the availble outlets
i suspect you could cut off the key on a CEE plug so it would fit both the yellow and blue sockets
