With a multi tester you can buy a inexpesive tester that will light up on your live wire,or simply look to see black,or red.

Use a multimeter set to measure AC voltage. Stick the red probe in an outlet and touch the black probe to a ground connection. If you see @110v, hot wire.

You need to use a voltmeter on the alternating current setting (usually a V with a wavy line above it). Place one probe on a known ground, such as the neutral bus and place the other probe on the wire being tested. If the meter reads 120v you know it is a hot wire.
