Answer 1

2) it is a ground.

The earth wire is only intended to carry electric current when the connected equipment develops an insulation fault. It is generally connected to metal cases and other parts of the equipment which may come into contact with humans, or should otherwise never carry a voltage. Electromagnetic interference filters and surge protectors dispose of unwanted electric charges via the earth wire.

Answer 2

In Ontario, Canada, the plug wire standard is:

black: 110 volts AC ("hot")

white: neutral (AKA return)

green: ground
