Need to hook 230 volts to car lift - Air Tools & Compressors

the spade terminals in the wiring box are marked the chart tells where the color wire goes to what terminal for what voltage then l1 and l2 is the incoming power hookups

On 230 volts you have 3 wires 2 are 115 volt and the third wire is ground. As long as you hook the ground wires together correctly the other wires don't matter. Usually the ground wire is either white or green. The black wires are hot (115 volts).

please verify the name plate to be 115 230 volt motor.there will be a schematic that shows you exactly how to hook up this motor depending on the voltage being supplied to it. The main thing is switching between 115 and 230 volts this is a selector switch this very easily forgotten about. Please make sure to check that and double check that to make sure its on the proper selected switch. Good luck

A thumbs up would be greatly appreciated if this answer is helpful to your free Fixya question

There are several items that will need to be changed or replaced. First rewire motor. Remove weather head cover. On the motor will be a tag that shows how to wire for 460 volts and 230 volts.Check the tag and present wiring to make sure they match. Then look at the 230 wiring and change wiring per motor tag. Again check the motor tag to see max amps at 460 volts and 230 volts. 230 volts will be higher than 460 volts. Check the starter (if so equiped) to see how many amps its rated for. You will probably have to replace the starter. Make sure it has a 230 volt coil. Next size the overload heaters for your amperage. This conversion is not a simple task unless you're familiar with electrical . Good luck!!!
Next the starter coil will need to be replaced with a 230 volt coil

If the plug has 4 poles on it, that means it should be connected to two lines of power, one neutral, and one earth ground. The unit probably has a 208-230 volt compressor, with 115 volt control and heater system. Let me know if you need more info

Hi, I am not quite sure of what kind of set-up you are saying you have when you say it says line ground natural? If you have a 115/230 volt power supply, this should be very easy to tie into. Look at the wiring diagram on the new unit real good and locate the 2- hot wires that should say line one or L-! and L-2. Your 230 volt wires will connect one to each side of those 2 connections, and will have a ground wire that grounds to a metal lug or screw on the unit. Look over the diagram for field wiring connections for high voltage and this will tell you where you need to hook your 230 volt wires and ground to. If this new unit is 208/230 volts, you should have connections like I have said either L-1 or t-1 and L-2 or T-2 that you will tie in your 230 volts to. Just look over the diagram and you will see where the beginning of the 2 hot wires come into the unit. There should be either 2 good sized black hot wires that are for your incoming hot wires to connect to, or they are already connected to the contactor, and you will need to connect yours to the line side of the contactor. I see what you are saying now, that they are only showing you 1- 115 volt connection to the new unit so you will have only 115 volts to run it. You want to know where the other 115 volt conductor hooks up for 230 volts. This is why you need to look at the schematic and wiring diagram that shows both of the 208/230 volt connections on this new unit so you can connect both hot wires to it. I can't pull up a picture of this on the Internet, but it will show you on the schematic on where they connect. This line ground neutral connection sounds as though its not for a hot wire, but for your ground, or if you happen to have a neutral wire that is being used for a ground. Please keep looking for the 2- line in connections as this is what you will need to find and where both 115 volt wires connect. They are your line voltage wires, so they need to connect to the load voltage hot wires at the L-1 and L-2 connections of this unit. This should be fairly laid out for you, but sounds like they have made it difficult? Look for what I have said and the schematic drawing and you will find the connections. Please don't forget to rate me as I know you will be kind. I will be checking back with you as I keep all of your information on file so I can look you back up if I need to. You can contact me by my user name below if you need me also. I wish you the best and follow my instructions and I know you will get it right.

In order to get 230 volts out of any 115 volt inverters you would need to be able to hook the outputs up in series with each other. If your inverters have outlets there is no way to do this other than completely dismantling both units and then I wouldn't advise it. As a licensed electrcian and electronics tech I've sometime done things like that but only as experiments or in emergencies.
If your units came with a power(+) and ground(-) you could then hook them up in series by fastening the (+) from one unit to the (-) of the other, then tape them to insulate them. You should then show 230 volts from the two leads still available. On the battery side you will still hook both postives(+) to the positive(+) and both ground(-) to the negative(-).
Notes:
* Depending on the internal wiring of your units the above description may not work and could damage or even ruin your inverters.
* Although you may get 230 volts this way you will not have more power(watts,Amps) than listed for one unit and you may even have less.
* You need to also beware this could VOID any warantees and shorten the life of these units.

IF YOU SEE ON THE LABEL ON THE MOTOR HOW TO CHANGE FROM HI - LO VOLTS . THATS ALL YA GOT TO DO ..THE WIRES HOOK UP NORMALY

Unless your household electrical service is running at 230 volts, there's absolutely no reason to set your supply for 230. When you choose the 230v setting the supply REQUIRES 230 volts to become operational...Which is not going to happen on a 115 volt service.

On a 230 volt std hook up here's the way it is supposed to work. From black to white you should get 115 volts. From Red to white you shoudl get 115 volts. From red to black you should get 230 volts.

Concentrate on getting the correct output from the generator with the load to the house disconnected

This should be 115v (black to white, 115 volts red to white and 230 volts red to black.

On the load side (ie, the house connected) what are you using? 115 volt lights, etc on one side of the
230 volts, and some other 115 volt loads on the other side.. Are there any 230 volt loads. It could be
that one side of the 230 volts (ie, a 115 volt side is drawing a lot more current than the 2nd 115 volt leg.

Get back with me on just what the loads are botth 115 volt and 230 volt . also what are the rating on the circuit breakers.
