SW Ohio | If I wanted to do timers and relays (control circuits) I would first use a small transformer (sized to load...relays and timers don't pull much) to get 110 VAC. Then there are hundreds of options, timers relays programmable controllers. You can make it do what you want and work in a safer voltage. The coils of most contactors can be changed out to 110 VAC. Or a 110 VAC relay with 480 rated contacts could be used. Then you don't need all the transformer info, just control logic. But the time may be right to get an electrician to keep it safe. Sometimes what you do works and is logical to you but hurts the next guy who expects it to be wired to certain standards.
Good Luck
Dave
