I'm replacing 15 yo MA600 with new MA600 but original dimmer has 2 black wires on top of switch. New switch has side connections. Question is, other than the ground wire, how do i determine which black wire goes where? Thanks for any guidance.

Hello Bruce41 - Thanks for your post! In this case of a single pole application with only 2 wires (other than ground) available to connect to the dimmer, you would attach one to the black terminal screw and the other to the brass --> If it doesn't work when you turn the breaker back on, turn the breaker off and then swap them around. We hope this helps!
