Ex(1) using 14-2 w/grnd wire to wire a 220V A/C or heater.
This will cause a fire hazard because the 14-2 is a light duty wire and the device connected to it will not run properly. This would fall under efficiency and safety.
Ex(2) using 6-3 wire to wire a 120V TV set or small A/C unit. 6-3 is a heavy gauge wire suitable for wiring Cooking Stoves and other multi circuited appliances. Really no safety issues but it isn't efficient to use this expensive wire when a less evpensive 12-3 wire would do the job. This would fall under efficiency.

When I was living in Singapore (about 10 years ago) some of the electrical sockets for domestic applicances were made of ceramic (for high insulation) but they were brittle and could shatter or bits could break off if you dropped them. A consumer might continue to use such an item after it was damaged or had exposed conductors.

The kind of electric range where the controls are on a back panel and you have to reach over the burners to adjust their temperature. You always read about someone wearing a loose-sleeved robe and setting themselves on fire by reaching across that hot burner.

A safety concern could be not having GFCI outlets near sinks. Or water proof outlets outside.
