Skill set = I am not a licensed electrician but I am more advanced than your average home improvement guy/gal. I have wired a standard 3 phase outlet from a 3 pole panel so im not completely lost until I ran into this motor.
Got a large ventilation van for free and I need it and would like to use it so I cracked open the motor wiring case because this fan has never been wired and it has 9 wires... now im confused. They are all yellow and labeled 1-9. On the tag it says 208-220/440. I thought 208 was 3 phase and 220 was single phase 220? I dont have a transformer for 440 so thats out. Can someone point me in the right direction on which wires to use to get this thing going without telling me to hire an electrician. Yes I have a 3 phase box.

Thank you.

It is right there on the lable.
For LO volts (208-220).
Connect 4-5-6 together.
Connect one hot to each pair of
1 and 7
2 and 8
3 and 9

 

Hi, how do you intend to control this motor? It will require overload protection as it does not appear to be thermally protected.

There are 208 volt three-phase wye and 240 volt three-phase Delta. There is also 240 volt single phase.

This motor is a three-phase motor and will require a phase converter. I would recommend looking at solid-state phase converters.

 

Hi Tolyn, OP states he has 3 phase available, must be an industrial or commercial location, no need for a converter.

2 hp is going to need a starter of some kind.

 

Not sure I understand above comment. Starting torque is provided by the 3 phase voltage.

 

So I can run this motor off of 240 single phase as well?

 

You can not run this motor off single phase.

 

Toyln Ironhand stated "240 single phase" that is why I questioned it. Thank you all for your replies.

 

If you have 3-phase available why ask about single-phase? That motor will only run on three-phase or single phase with some type of phase converter added.

 

Hi, post a pic of your supply panel, if you are not in a commercial/ industrial area it’s doubtful you have 3 phase.

Its up and running, Thanks for all the help and insight

I asked about single phase because where I wanted to install the fan is 30 meters from the panel and running 12/3 that far is more expensive.
