Right i am going t be running power to my shed from the main consumer unit in the house to a secondary consumer unit in the shed that will be used to run power to the shed and also the garage that is joined on next door along with a lighting circuit for both and also a seperate power circuit for the pond electrics.

The maximum that will be runnnig off thefeed to the secondary consumer unit will be...

3 hallogen strip lights
1 med pond pump + 1 small pump during the summer
1 small UV biofilter
poss a 2hp compressor or parts washer or 150amp mig plus a power tool or 2.

What diameter wire should i run between the two consumer units?

and i know that i will need to get an approved electrician to actually connect everything but i can do all the wiring ready for him to come just want the wires in situe so its alot cheaper.

 

How long is the cable run m8 ?

 

well first of all you will want a steel wire armoured cable (SWA), i would get one with 10mm cores, as you cant really go much wrong( depending on the run, presuming not very far), best thing to do is let us know the cable run first, then i can work out how much load you can put onto certain cables.
Also what do u mean by halogen strip lights? flourescent would be the way to go mate !

 

just a small note,, its always cable area and not diameter we always quote!

 

perfect timing on the question, i am about to do almost the exact same thing although i already have the armoured cable.

just need an electrician in the berkshire area to come and do a cash evening job on it now if anybody knows anyone?

 

also really need to know how the cable is to be run, wether it is going to be buried or clipped to a wall etc.

 

sorry was half dead last night! yeah its not halogen but florecent strips that i have uin the shed and garage already running off an extension lead but wanna do it properly now!

yeah it would be armoured cable and would be clipped to the wall.... i would say it woud be between 20 - 30mtrs of armoured run between consumer units.
