I'm sure you dont have aluminum wire unless yer in a old manufactured home. On the previous point, I really cant even believe they ever even came up with the stab lock idea. Making it "easy" for homeowners to do their own electrical is bad juju.

I couldn't agree more. We're having EVERYTHING ✔ Checked just to make sure!

From Wikipedia:

"In North American residential construction, aluminum wire was used for wiring entire houses for a short time from the 1960s to the mid-1970s during a period of high copper prices. Electrical devices (outlets, switches, lighting, fans, etc.) at the time were not designed with the particular properties of the aluminum wire being used in mind, and there were some issues related to the properties of the wire itself, making the installations with aluminum wire much more susceptible to problems. Revised manufacturing standards for both the wire and the devices were developed to reduce the problems. Existing homes with this older aluminum wiring used in branch circuits present a potential fire hazard."

Push in outlets and switches was promoted to be a time (money) saver for residential electricians.
