Hi all,
With a few financial goals ticked off in the last few months, I'm looking at options wrt supplying power to my shed. SWWMBO has even offered to make it my birthday present, including 3 phase if it's indeed doable. Until a couple of weeks ago, I had envisaged running single phase to the shed from the house. ATM we only have single phase at our house. Recent purchases and potential future purchases have made me look at the possibility of supplying 3 phase to the shed. I did have the option of connecting 3 phase to the house but the builders wanted an extra $2500 for that luxury and at the time I figured I would never need it! :doh:
So far everything is looking promising. There is definitely 3 phase in the power pit. I have a couple of mates who are sparkys, and while they have not looked at the setup, they seem to think it is doable. There is one stumbling block that I can see however, from the power meter, the power needs to somehow get from one side of our (concrete) driveway to the other. There is a piece of 100mm sewer pipe that goes from one side of the driveway to the other side to facilitate running services without digging up the driveway. I have excavated and exposed it to find that the plumbers have used it to route the polypipe for water supply to the house through it. Where do I stand wrt now routing some orange conduit through there? Its about 3M in length and so the power will be running next to the water for about that length.
I'm just trying to establish as many facts as possible before spending any money :U Also what sort of circuit should I consider to be sufficient for my needs? The shed is about 100M from the power meter. While I'm not qualified to make these decisions/calculations I have used an online calculator to work out some basics. 16 sqmm 3 phase cable should be able to provide about 40A (allowing a maximum of 5% voltage drop) maybe even 48A or so. I can't see that I will EVER draw that amount of current, since I never operate more than 1 or maybe 2 tools at any one time. Even if I was to purchase a machine tool that required say 5 HP, it would not go near that. Bearing in mind that I am not setting this up as a commercial venture, it's purely a hobby and will remain that.
Will 40A do?
Cheers,
Simon
