The green (or green with yellow strips) is for Earth. This is

the D shaped socket in a US outlet. The Black (US) or Brown (UK) is

for Live. This is the narrow rectangular socket on a US outlet. The

White (US) or Blue (UK) is for Neutral. This is the wide

rectangular outlet on a US socket. The color code may vary for

other countries, so be sure to check.
