Why 32amp ring? Will not a 16amp radial do?

he wants to use a few power tools so i thought a 32 would be better if he has a heater plugged in whilst driling.

prob 40A at at the main cu

WTF is he drilling (joke lol). If he is only using 1 heater (max 13amps) then any portable hand tools are only going to be used for short periods of time so your not going to get an overload, so why not say put in a 20amp radial then for his sockets.

6mm cable on 32amp can according to OSG be 49 metres in length.

It does say 40 metres on a 40amp type B cb/rcbo, I dont know but I wouldnt personally want to go that high.

Don't forget your volt drop calcs need to include the circuits in the garage - you can't use up all your 3% [*]on the distribution circuit!

* he is having lights, isn't he!

Oh, and I have found that in the winter a 3kW fan heater makes no appreciable impression in a garage (mine is a fairly new brick jobby). I use a small propane space heater.

32A is not unreasonable. What if he wants to use a welder? 16A would be barely adequate.

My own garage has it's own 32A ring for this very reason.

Prodave , you're doing the classic sparky thing there " What if he wants to use a welder?" I always try to avoid those assumptions , no one has mentioned a welder .

Another classic is " I always wire showers in 10mm in case someone wants to fit a 10.5 KW shower " (In 10 years time !!!) Perhaps its very comendable but its not a road that I go down .

Would say that in most cases 20A would be plenty for sockets although I

agree with Prodave, my own garage has a 40A supply for the same reason in case I want to use a welder.

But then I wired my own garage, with my cable and my money. I don't mind future proofing my own house, but is sometimes difficult convincing other people when other they are paying.
