"RED HOT"

Answer 2

the red one

Answer 3

DO NOT do anything with the mains. Get an electrician or there is a high chance of getting electrocuted.

Also, You didn't say where you are from, so there is no way to give you a definite answer. The colours are not universal. In Australia, Red is active and Black is neutral.

Answer 4

Both are line voltage wires in a residential use.  Call a qualified professional electrician to do the work since you need this help.

Answer 5

BOTH! In 240V system both the red and black are live. Then you should have a white (neutral) wire when connected to either the red or black gives you120V. Green is earthed.

If you don't know what your doing call an electrician before someone on here gets you killed!
