Im trying to wire up a 3phase 480 volt contater with a 120 volt coil contacter didnt come with any drawings not sure how to wire it up using a remote start stop button

Is the fixture 120, 240,208 480 volt? Need a little more on model number. Is it 400

there is no capacitor in 3 phase motors. if you are trying to tun 480 motor on 240 or 208 there is a wiring plate on motor, perhaps you should not attempt this., you do know that the amperage will increase if you run lower voltage.

no,it is wired for 120 you can only run two legs to make 240.you need a different generator for that

I would suggest taking a closer look at the motor name plate. I am not familiar with a 120/240 three phase service. When I checked the web it shows: Voltage 115/230 (that is single phase), Max Amps 115 Volts = 19.2 Max Amps 230 Volts = 9.6 , Single Speed, Square Flange, RPM = 3450, Threaded Shaft, Frame = 48Y Used on the following models: Sta-Rite Max-E-Glas, Max-E-Glas II, Dura-Glas, Dura-Glas II, Dyna-Glas, Dyna-Max Pentair Whisperflow, Pinnacle and Anthony AR2 Series. You should also show what voltage you are connected to.

Need to check the low voltage circuit for 24 volts, the 480 volt to 24 volt transformer may have a circuit protection reset or fuse installed. All the 3 phase electric heaters use a low voltage control circuit for operation of relays (24 volt coils).

From what I found, 480 volt, 3-phase is 480 volts from leg to leg.
It is also 277 volts from each leg to neutral.
One can use a step down transformer to reduce the 480, 3-phase to 208 v, 3-phase and then each leg of the transformed voltage would be 120 volts to neutral. Try to locate the transformer in or near the chiller control cabinet.

You cannot wire a three phase motor for single phase and you cannot wire a single phase motor for three phase. If you have a three phase dual voltage motor your options are 220 or 440 volts. If you have a single phase dual voltage motor your options are 120 or 240 volts. A 208 volt Hobart motor will only function correctly on 208 volts and is not dual voltage.

Yes it can be done but it is hard to make it look good. To do it you will need to create a 24 volt control circuit by means of a step down transformer from 120 volt to 24 volt. Next you will need a t-stat normal home style and hang it where you want it. Then you will run t-stat wire from the transformer to the t-stat and then from the t-stat to a contacter switch that has a 24 volt coil on it and it is placed between the ac and your power source. To do this you must either cut the plug off the exist ac cord or replace it with other wire so that you can get it into the contacter on one side and on the other side is power from the wall. So what happens is when the t-stat calls for cool it's switch will close allowing the 24volt to energize the coil on the contacter therby making the connection to 120 volt bringing on the A/C.

The dryer should work ok on 208 volts. The drying time may be a bit longer than usual since at 208 volts, you will only have 5408 watts of heat. Your bigger problem is your three phase panel. You can hook up one "hot wire" from the dryer to any of the three 3phase wires, and the other "hot wire" from the dryer to either of the two remaining 3phase connections and you will have a good connection to your dryer. However, the third wire from the dryer is a "ground wire" which has no connection in the three phase panel, or at least you didn't say it has one. If you can pull a ground wire from the grounding lug of the service panel feeding your 3phase box, and connect it to the third wire on the dryer, you would have a safe connection.

At 208v, the dryer will pull 26 amps. Be careful and make the right connections.

The voltage can be found on the wiring diagram.
