I need to wire two AC systems so they will not come on when a generator can not handle the load. The Generac ATS has built in contols so you can conveniently interupt the control circuit to the condensing units but I can't get to them. The ATS also has 120 volt outputs meant to control line voltage relays for whatever heavy loads you want to manage while the generator is on. I'm using two pole relays that are sold by Guardian. They have a 120 volt coil and 40 amp two pole contacts. They call it a DLM module.
My question is: is there any reason I have to interupt both legs of the 230 volt circuits to the condensing units? Or can i just control one of the legs? I ask because the relays they offer are in very small enclosures. Running 8-2 NM in and out looks like it would be really difficult.
