options for workshop supply

[A032701]

just wondering what people would think would be the best way of doing this.

i have got to provide a supply up to a workshop in a garden (about 80 mtrs from the house). it will run underground all the way and then in the subfloor of the house that is currently being worked on all the way to the db.

I'd also be leaning to a fuse at the supply end. Any other services in this workshop such as water, gas etc?

It may be worth the customer enquiring of the DNO the cost of providing a separate supply to the garage. Depending on routing on their side, this may be relatively inexpensive and would give greater scope.

thanks everyone.
the garage/shed will be around 9mtrs x 10 mtrs.
their will most likely be water but no gas.
i will look into the possibility of getting a separate supply in

As you haven't provided a design current it is easier to use In. This also means you are covered for volt drop right up to the point of overload of the distribution circuit. 32A you could go 10mm, if you go 16mm, you can do 50A. Using In instead of Ib and youve got a VD just under 5% for both.

Check Ze. You have TNS so could be up to 0.8 ohms already....

C40 60890 max Zs is 0.54

R1+R2 for the 10mm is 0.35

R1+R2 for the 16mm is 0.23
