Circuit design

[i=p/u]

A guy asked me to install supply to 3 ph oven, as its few miles away I looked at same kind in another of shops , and it was installed on 32A breaker on 6mm. Anyway I got the rating plate sent to me by photo and I working out 2.5mm on 16A 3ph breaker, am I missing something... I could be but doubt it.

It's no probs to me. As for manuals I'd say maybe still in France . We as sparks should be able to determine supply conductors from that rating plate. Which I work out as 2.5mm on 16A tp breaker. Plenty of 2.5 about where I'd have to go buy 4mm

problem is that if it's designed for 230V/3 phase, you won't have that supply and you will need to convert to single phase with a line current of 44A.

Need to look at the manufactures data, and connection diagram. But these European ovens tend to be suitable for most, if not all, of European voltage bands in one way or another!! lol!!

May be one like this I came across a week or so ago

 

[Engineer54]

Yep that's about it, ...suitable for several different European countries supply bands etc...

Aye well it came from another shop no doubt so = 5c 3ph and N.

So my 2.5mm conductors more than adequate

are you all on drugs ?
the label clearly says 240v / 50hz !
and 3 phase wont be signified by the "T~" either , dual voltage supply would be stated
with a 230/400 stamp , and there isnt one.
which is why its been wired in 6mm at the other shop , and thats probably too small for a 44A load anyway.

Your miles out mate , 10.2kw oven
The oven will have 3phase ability but the l1 l2 l3 connections can be linked out manufacturers usually provide links

Well I was thinking its wired in the 10mm 5c flex to cover all voltage set ups, and relating to the 6mm is for 3 ph which is overly sized...

Your doesn't say that on the plate. To me its single phase looking at the plate. To save all this guess work why not get them to send you a pic of how it's wired. Or just go and look at it

Yes linked out if you want to run single phase, I understand this, what am asking is 10.2kw split over 3ph = 15A per phase and that's not taking diversity into it...
So my calcs say 2.5mm is more than adequate..

Do you agree hen

Do I agree then ? Yeah sounds about right mate

Has to be 3ph set up, he didn't get from France , would of came from a shop in uk..

Wouldn't like to put any money on it would you?? lol!!
