380 volt

[eagleeye]

A friend of mine has just bought a pizza oven and the rating looks like 380 volt single phase at 4.5kW. Any idea how I can connect this to our current supply ? It's definitely single phase as the thick flew coming out of the unit is only 3 core (live, natural, earth)

thick flew??

 

[GMES]

Flex Possibly ??????????????????

 

[eagleeye]

Yeah sorry. Bloody predicted text. Yes I ment thick flex

 

[Pete999]

Can you post a picture of any circuit diagrams you have?

 

[snowhead]

Is this a Commercial oven?

Is it new?
If not have you looked inside to see if what the flex is connected to?

Have you looked inside to see what the 3 core is connected to?
If not try continuity from oven casing to "Earth" in the flex.

Photo of the Data plate would be good.

Sounds more like it must be a two phase system, though I would not expect it for ovens.
I cannot see how you can get 380V ac single phase, but L1 and L2 instead of L and N could do it but the supply would be unbalanced.

The same as 2 phase welders.

 

[eagleeye]

spec plate on unit. I think its classed as a commercial unit yes

 

[Pete999]

I would say so

 

[eagleeye]

notice it says 4.5kW/h though so this can't be the actual power rating of the unit ? and also say electrical connection 380 ? is that some kind of connection or is this the voltage rating ??

I've come across them before, along with commercial washing machines and of course some welders

It could be, 4.5kw is not unusual.Though the information plate is a bit vague! I'd expect to see the current rating on the plate and the voltage marked as 380/400v? Is there no paper work? It might be an Idea to go online search the model and make of the unit and check out the supply requirements?

Is this the oven model? https://translate.google.co.uk/tran...//www.mirror.es/index.php?lang=en&prev=search

It shows it as 4.5kw- 380v -3 phase

What colours are the individual wires in the flex? and what size do you estimate the wires to be csa
