size of garage cable

[harpmeister]

Hi
I am a couple of months off needing a electrician to wire up my garage for electricity but since I have the patio dug up I thought I would lay the swa down whilst I was at it.

My question is what size cable of swa would I need and would it be better to use 2 or 3 core.

The cable run would be just under 25m long from the CU in the house into the garage, the first 16m would be clipped to the external house wall with another 6m buried under the patio, I am looking to run a light circuit comprising of 2 36w fluorescent tubes and a mains circuit of 3 double sockets to run a small lathe rated at 500w, pillar drill rated at 350w, bench grinder rated at 250w and possibly a small heater so maybe 2.5kw in total, bearing in mind that all the tools will not be used at the same time.

I don't plan on doing any of the electrical work I just need to know the size of cable.

Many Thanks

Just put two lengths of flexible underground ducting in. Photograph them before covering with some kind of proof of depth. Don't forget pull strings. Try to come up inside at both ends if possible.

Twinwall ducting is what you want, of a generous size.
