Checking Wires

1. Use the voltage tester to test a powered

electrical cable to make sure the voltage

tester is working. If the voltage tester lights

up, it’s working.

2. To avoid electric shock, before installation,

TURN OFF POWER by turning off the

circuit breaker.

Note: You may need to shut off more than

one circuit breaker or switch to make sure the

power is off.

3. Unscrew and remove the faceplate from the

old light switch.

4. Use the voltage tester to test around the

old light switch, and ip your light switch on

and off a few times to make sure that the

power is OFF. The voltage tester should not

light up, and the light should not turn on.

5. Unscrew and pull out the old light switch

(without detaching the wires).

6. Check to see if there are 4 wires connected

to your old light switch. These wires are the

ground, load, line (or “live”), and neutral

wires. If you do not see 4 wires in the

junction box, the smart light switch may

not be compatible with that switch. You can

check other switches in your home to see if

there are compatible switches.
