Evening all..
A friend/customer has just asked if I could connect up this commercial washing machine down at his domestic stables. He has had it in his house for 10 years. Recently it has started tripping the B40 MCB. It does not trip immediately so I don't think it is the inrush, plus it did not trip the MCB for many years.
Having never worked with 3 phase machines I am unsure of what the diagrams mean in the photo below labelled 'spec'. On the right of the rating plate It shows the N L1 L2 L3 terminals and then what looks like 3 different options. I.e 220 - 240V, 3 x 220-240V, 3 x 380-400V.
My questions are :
1. can this machine be run on single phase, if so are the connections just to N and L1 or would there need to be a link from L1 to L2 and L3?
2. What is 3 x 220-240V? Is this 3 different line conductors at the stated voltage?
3. On the left of the rating plate it says 3 - 5 x 20mm. What is this referring to?
4. On the left of the rating plate it says 100A 250V with a symbol before it that is like an h but with a horizontal bit on the top of the h. What is this symbol and is this the rated current?
I have added another picture showing the model number in case this helps.
Cheers all
