Inside the box is the transfer switch that can be actuated manually or electrically. The switch has two solenoids and two snap action switches. The solenoids are rated for 240 volts. The switches for 600 volts. I want to use a momentary contact rotary switch to actuate the solenoids. I am not sure how the snap action switches are wired yet but I think theyare already wired the way I want them to be. I want the snap action switches to remove power from the solenoid that is being powered to cause the transfer switch to move. That way once the solenoid has done its job it will no longer be powered no matter how long the rotary switch is held in the on position for that particular solenoid. I don't see a problem with this. Is my scheme OK? Thanks, Eric That depends on the timing of the switches to the positions of the transfer switch. My guess here is they will transition when the transfer switch is FULLY on in either generator or utility position. This would jive with your you're trying to do. Indicating something like "in the middle of switching" would be pretty useless, and something the controller could detect itself. The question is moot now. The panel passed inspection. Even got the green sticker on the main panel to prove it. Eric |

Yeah, the green sticker is what WA state uses to show that the electrical work has passed inspection. It is filled out by the inspector with the date and so on. Eric |
