North of the border, every electrician I have talked to will not use the spring loaded push in terminals, the time you save using them does not justify the time you spend trouble shooting a problem. However in the early 1980's the opposite was true (the condo I live in, was built with the electrician using receptacles that only had push in terminals (no screw terminals}). The use of push in terminals was common then. Perhaps we have learned something.
