Troubleshoot box timers

Turn circuit breaker fully OFF and then back ON
Check that only copper wire and no insulation is under screw plate.
Check rating plate on timer and Load. Make sure timer is rated for the Load amps.
Check rating plate on timer for voltage. Match voltage with electric supply.
Check rating plate on Load. Match voltage of timer with voltage of Load
Use only solid copper wire. No stranded wire.
Keep box cover closed
Maximum 2 wires under screw plate
Only copper wire under screw plate. Cut back insulation so no insulation under screw plate.
Check wiring See box timer wiring

Match wire size and breaker and load

NO stranded wire
Solder end of stranded wire to make solid

Both wires MUST be same gauge
Straighten each wire
Tighten screw very tight against copper wire

Use wire connector  
Push on wire connectors
Use push-on wire connectors

3 wires/ or different gauge wires

Join wires with wire connector or push-on connector
Run jumper to screw terminal.

10-3-wire
10-3-wire  12 Ga

10 gauge or 12 gauge?

10 gauge is larger/ for 30 amp breaker. 12 gauge is smaller/ for 20 amp breaker
10 gauge wire can have black-white or black-red
12 gauge will have black and white wires

Buy short pieces 10 and 12 gauge wire at local box store
Compare with your wire.
Match color code and amp rating for wire
With 120 and 277 Volt circuits, white wire is always Neutral, and black is Hot
With 208 and 240 circuits, both wires are Hot, and both wires carry voltage
Add black tape when white wire carries voltage (applies to 208 and 240V circuits)
