ECN Forum Forums General Topics of the Trade General Discussion Area Need some fast help

Im installing a starter/over loads for a 10hp aircompressor. The starter is a GE CL08. Its a 3 phase starter but the compressor is single phase. A switch will turn of the coil when not used and there is a presssure switch on the compressor. Can anyone plz help me out fast. The one I installed worked for a week then the coil was toast. its a 120volt coil . Plz help im in a panic.

!0 hp, do you have a control transformer on this 120 volt coil?

its 10hp no control transformer

coil 120v so im sure i dont need one

You do if your supplying it with 240 V. That would explain the toasted coil, they dont seem to like being hit with 2X rated voltage. ;<)

How can i fix it?

Anyone have a diagram?

Anyone?

Is there a neutral in the control panel or is it just straight 240v?
If all you have is 240v you will have to install a control transformer or change the coil in your contactor to a 240v coil.

you should able to see the coil and replace it with proper voltage coil as what Bigrockk saying there if straght 240 volt no netual wire then you have to use the 240 volt coil it is a stock item.

but i dont have the part number with me at the moment but if you can read the box cover it should be on it.
