I have a question about a Legrand RCD11WCC6 two single pole light switch. I'm going to be wiring this up to control a vanity light and then use the second on/off switch to separately control a recessed ceiling light.
This product has two common screws in back, and it has a plastic "split tab" that can be pulled out. The instructions say "removal of the split circuit tab allows the device to be wired with two separate circuits". I assume that they mean that you would leave the tab in if you had 2 hots coming into the switch box from two different circuit breakers? I just have 1 hot coming in. So I assume that means that I leave the tab in. But does it matter which black screw I connect the hot to? On one side there's a black screw between the two load screws, and then there's the second black crew on the other side all by itself. Green ground screw is on the bottom.

 

Leave the split tab in place and use either screw for hot.
The two screws on the opposite side where the green screw is are for the loads.
