I have been upgrading to grounded outlets in my 1950s house and I just want to make sure that this particular outlet was wired appropriately by the previous homeowner. This outlet is controlled by a switch. In the switch box, two black wires are secured to one brass post, while one red wire is secured to another brass post. In the outlet box, there is one capped black wire. One red wire runs to the brass connections and two white wires to the silver connections. I wired the new outlet the same way but added a ground that connects to the metal box (Later, I rewired the new outlet to the screws, not the push in connectors).
My ground tester confirms it's grounded. Is there anything I need to change here or should be concerned about?
