Connecting to Smart Switch - Existing has 3 Black Wires, No Ground
Hi All, I am trying to replace an existing single pole light switch with a smart switch.
The existing switch has 3 black wires going into it (2 back stubbed) and one to the screw on the side. I assume one top back stub (A) is live. The adjacenct screwed black wire (B) carries live to other switches in the room. And the bottom backstab is the lout wire (takes power when switch is turned on).
and a bunch of white wires are bundled together in the box.
The new smart switch (Meross MSS510) has 4 wires. Live lout neutral and ground.
Questions :
a) How do I make the connections?
b) Can I combine the 2 black wires (A and B) and the live from the smart switch with a single cap?
c) As there is no ground wire, can I leave the ground in new switch empty?
Thanks in advance.

Reason: Incomplete details
b, Yes, combine the two blacks with the line in.
c. There has to be ground in there somewhere. Since the box is metal connect the switch ground to one of the ground screws in the bottom of the box.
Hello everyone,
I am working on getting lights installed in my new house and would like to share the environment and my ideas and you can tell me if there is either an easier way OR if I'm being an idiot and my method would either be dangerous or wouldn't work at all.
Scenario: I have a light switch that controls an outlet and have no existing lighting. We would like to install some recessed lights, and have attic access for this area.
I believe there is a line coming from the outlet TO the switch, then another line that returns the power from the switch TO the outlet. So... with all this said lets get into my thoughts and someone can tell me if I'm being silly. I feel I should be able to find the "return" line from the attic and cut it (12/3) put in a junction box and connect the following wires. All whites together, all ground together, Black to black ( for outlet ), Red to black ( new line for lights (new line will be 12/2))
Please let me know if this is a safety hazard, if so why, if this theory should work, and if you can think of an easier way about this.
I am here to learn and maybe save a couple bucks all while doing it, but priority one is always safety!
Thanks in advance!
I am installing a ring floodlight camera. I removed the old floodlight, one black wire, one white wire, no ground wire. The junction box on the eave is metal, tested with mulitmeter to see if box was grounded, it's not. How do I ground the new floodlight?
