But i'd be surprised if it was more than 16A per phase to be honest.

GU10 LEDs don't care about polarity, and i never seen a coffee machine i rated at better than 2 out of 10.

Some coffee machines have dual wiring options so you can choose depending on the power supply available. How big is the machine, how many coffee heads has it got?

il find out tomorrow ,marvo, could do with the manual but i know a similar one is on 32A breakers, wired in 4mm but maybe this is an oversight on the the installer

i just cant see a coffee machine pulling more than 20A on each phase..

I don't see it either. A 3 head machine would be 4-8Kw depending on the volume it's designed for and the elements, usually 3 of them, are generally 230v. I'd be surprised if it's more than 10A per phase on a 3-phase supply.

I've just nicked this from a manufacturers web site:-

"Most high volume espresso machines need minimum 20 amp power supply. This allows the water boilers to recover quickly after water of steam has been drawn off. The most common espresso machines are two group machines. Usually they have two team wands allowing more than one operator to use the machine at any one time. A 10 litre boiler and a 20 amp power supply should be ample for most small to medium requirements.Three and four group espresso machines have larger water boilers and may need 30 amp or 3 phase power supplies."

Ipu, I think it may be best looking at the manufacturers details on this one mate. But going by what we know already I'd say a 32A type C 2.5 ring would be fine but look at the specs and that should give you all the info needed to design the circuit. Good luck and tell us how it goes and how it tastes.

Go to the forum from the orange bar at the top of the page, choose an appropriate category from the list of forums e.g general electrical or new member introductions and then near the top of the page is a button labelled "post new thread".

If you do clamp it up check the Amp draw from cold start up (worst case) - elements normally pull more Amps while warming the water then drop off when top up heating - just my 2 pence worth.
