An AZ electrician told a friend of mine that if he (the electrician) replaces receptacles and switches in my friend's AZ house that code requires him to use the push-in "stab" connections on the receptacles and switches instead of the screw terminals. This is a special situation in that the electrician would be doing "pig tailing" to connect the aluminum household wiring to copper wire before connecting the copper wires to the receptacles and switches.
Anyone know if this statement is correct in AZ? - or perhaps only in the Phoenix area? If it's true, what would be the reason for such a code?
