Neutral wire required

Does Box have neutral wire?
Turn power off
Separate wires for testing
Test each wire to bare ground wire
When tester lights up, that is Hot wire.
Test Hot wire to all other wires (except ground wire)
When tester lights up, that is Neutral wire

Many switch boxes do NOT have neutral wire.

Do not overload the circuit

Match wire size and breaker size
Safe maximum is 80% rated load
20 amp breaker x 80% = 16 amps.
Volts x amps = watts
Figure breaker size and wire size
Stress test the breaker panel

120Volt and 240Volt breakers

Image shows 120Volt line and 240volt line.
Both circuits have ground wire.
Each 120 and 240 require two wires to complete circuit.
120V requires 1 hot and 1 neutral
240V requires 2 hots
Ground wires are for safety.
Read more about 240 volt

Some 240Volt lines have additional neutral wire. However, neutral not necessary to complete 240Volt circuit.
Some 240Volt lines have white and black instead of red and black

Most service boxes today have separate Neutral and Ground busbars, but these busbars are bonded together electrically, and are the same.
Illustration on left shows both Neutrals and Grounds on same side of box. In actual box, the Neutral is on right side and ground on left. Illustration shows separated neutral and ground so it is easier to illustrate wires leaving breakers.
