What fuse do I use here?

My first 4s2p, what fuse do I use from panels to scc? Gauge is 10 awg 20 feet one way.

The panels are self limiting. You can short those wires all day long and nothing will come of it.

You usually don't need fuses until your panel array gets to be 3P or more. If you were to add fuses they would go on each string on the panel side of the Y connector.

Where you have the red circle you want the disconnect switch. I thought we talked about a 2-pole DC breaker for the disconnect switch in one of your other threads. Maybe that was someone else's thread.

Yes I'll stick a 2P dc breaker thank you.
