Thanks Flip and Etienne for your information about the electricity and network cables, It will be useful.
Youre welcome

i dont know how many power you are going to use in the shed, but maybe its recommended that you bring "3 fase" (380V) to the shed, and from there install a fusebox in the shed where you can devide the 3 cores into 3 seperate groups of 16 Amps
in that way you can suck a total of 220v*16a= 3520w * 3 groups = 10560 Watts
i think 10 Kilowatt will be sufficient to feed the shed

ps use minimal Cat5e cable or higher with massive core and connect these on the ends instead of crimp connectors:
that will save you alot of headache...

and maybe its useless to mention, but put in 2 cables of ethernetcable, you never know you need more than one cable in the future, or that there is something wrong with one of the cables, in that way you have a "spare" cable witch is ready to go
