 Safety when testing wires: Never touch wet or previously flooded appliance. Never stand on wet surface when working on electric. Never stand on bare soil, put down dry boards. Tape tester leads to wood sticks to keep hands away from power. Use non-contact voltage tester before touching wires. Never touch or lean into any made of metal. Remove metal objects from pockets. Do not use oxygen or fuel accelerants in same room as electrical repairs Resource: Basic house wiring |

ST01 dawn-dusk timer: reverse photo eye using any voltage
12-24-120-240 Volt photo eye Why is this a photoeye? ST01 timer is astronomic dusk to dawn timer. Same as photoeye is dusk to dawn. When red and blue wires are connected, timer reverses into dawn-to-dusk So load is ON in day and OFF at night Adjustable to time zone, ST01 timer works with any voltage/ 12-24-28-120-208-240-277 Volt ST01 is battery operated and needs no voltage to run timer. Freezing temps shorten battery life to 20 days. ST01 has 1 year warranty, Ei600 has 5 year warranty Buy: Intermatic ST01 timer at Amazon CR2 replacement battery at Amazon Resource: Intermatic timers: ST01C & Ei600 More wiring for ST01C + ST01C programming Sell sheet with model numbers Load ratings for Intermatic timers/ pdf Load rating for ST01 timer: 120V ac, 6A, 208-277V ac; DC Loads 4A 12V dc, 2A 28V dc; Motors 1HP 120VAC, 2HP 240V ac, Ballast 16A 120V ac, 208-277V ac; Resistive 20A 120-277Vac. |

208-240
Volt photocell wiring 120Volt photo eye can control 240Volt load as long as Neutral wire is present. Photo eye control requires Neutral wire to power the internal switch. (Or for non-code-compliant solution, connect white wire on photocell to bare ground wire) 240Volt circuit can be turned off by turning off power to either Hot1 or Hot2. This is called turning off 'one leg' in 240V circuit. 12-3 wire or 10-3 wire is needed to provide 2 hot legs and 1 neutral Resource Read about 240Volt circuit |

How to wire photoeye so it turns
off 4 hours later 1-2-3-4-5-6-8 hours later Down to the minute, second, or hours Add delay timer to photoeye circuit Light turns on normally at dusk, then turns off after preset time expires. Set the delay timer to the exact minute, second or hour. Delay timer activates when photeye turns ON, and light turns on normally. When delay period expires, the light turns off, and timer resets to zero,. Timer and light remain OFF until photoeye activates the circuit again next night. Illustration shows twin timer.
