SSR keeps melting.

If it's melting on the power supply side, that's the supply side, not the load side as stated in your first post. Important distinction!

Are you using crimp type connectors on those wires, or are the wires wrapped around the terminal screws or under the terminal clamp plates?

A photo of the damaged device would be helpful.

I am using 12 gauge wire and just using bare wires into the screw terminals. it is melting on the side the power supply is attached to, not the side my control board is attached to. I have used the Omron and a different SSR with no long term luck.
