I called Kilovac directly and went through their phone menu and got their engineer that provides support for the contactors. That is the guy that send us the free contactors. I don't think I spoke to anyone else other than that particular guy at kilovac.
Antoant, what number did you call for Kilovac? I got a contact number from the internet but it doesn't look like its the right one. Also, do you remember the name of the guy you spoke to at Kilovac?
