  Copper ground wire. Every device, load, metal enclosure etc must be grounded. Ground wire must be continuous throughout installation, never switched on-off, never used as a Neutral wire. Generally ... use same size as other wire in circuit Buy: 12 gauge copper ground wire Ground wire Green ground wire Ground pigtails Ground rods/ ground clamps at Amazon |
 Non metallic flexible cables must carry ground wire, but do not have hazard of short circuit causing injury from shock. Armored steel cable can be used as a grounded connection, and will protect wires from damage. Metal can be energized from an insulation failure. All conduit ...metal, plastic ... flexible and rigid ... must be attached to structure, and attached to enclosures, boxes. Movement, damage and deterioration are major cause of electrical failure. Buy: Non-metallic flexible conduit Power whip Armored cable Southwire armored cable cutter Pull boxes |
 Electrical tools must be insulated. Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.

 Protect wiring from damage Use nipper instead of pliers or screwdriver for removing staples (and nails). Do not damage cable or wires inside cable. -Code says: Cable SHALL BE secured without damage to the outer covering. NEC sec. 336-15 Buy End cutting nippers at Amazon |
  Electrically insulated tools When removing insulation from wire, do NOT score or put cuts on surface of copper wire. Doing so increases resistance and heat on wire and creates possible weak point. Buy tools: KLEIN TOOLS Wire strippers at Amazon Electric Wire Stripping Machine Linesman pliers Utility knife at Amazon |
 Multimeters Voltage is tested across two separate wires. Ohms or resistance is tested across both ends of same wire. Amperage is tested along one or two points on same wire. Buy: Analog multimeter Multimeters at Amazon Klein multimeter Electric testers at Amazon Clampmeter for testing amp flow on line |
 GFCI circuit breaker A GFCI circuit breaker will protect all boxes on circuit. Circuit must be grounded. Ground wire must be continuous and connected to each piece of equipment. White wire on circuit breaker must be connected to Neutral busbar inside the breaker panel. Buy GFCI circuit breakers |

Check that photo eye
rating matches voltage and wattage of Load. Each device has a volt and
amp rating located on the device. Some are rated 120-277, other rated
240 volt etc. 2) Blink on during day ... incorrect wiring 3) blink during night .... too much local light, turn photo eye away from light. Sodium bulb near end of life. Test by covering eye with black tape. 4) never turns off: low line voltage, wrong voltage rating, excessive load (you cannot use a photoeye to control 1 Hp motor for example) 5) never turns on: lamp burned out, voltage too high, wrong voltage, too much ambient light, device defective or burned out. 6) operates normally for a while and then remains on ,,, excess load (motor, too many bulbs) and contacts are fused. Replace photo eye. 7) fails to turn off, and appears burned ... lightning strike or surge might have burned out photoeye Check that power line is not running under or over voltage Check that wiring is correct using diagrams below. With large loads such as several lights or motor etc, use photoeye to turn a contactor ON-OFF and let the contactor points handle heavy amp load. For high inrush LED type fixtures, the photo control switch should be rated for more amps than simply adding up the amp load on fixture. For example, ten 800 Lumens (60 watt equilavent) LED bulbs might pull 7 watts each or 70 watts total while turned ON. 70 watts divided by 120 volt = .6 amp. During start up, all 'inductive' loads such as motors, contactors, and LEDs pull more amps for a brief moment. Amp draw creates heat that can melt or damage parts. 10 LED bulbs would never generate enough heat to damage typical household photo eye. However with larger installations, that were originally designed for resistance loads instead of inductive LEDs, the issue might require more frequent replacement, or a contactor to handle the amps.

120 Volt photocell wiring Photo eye control requires Neutral wire to power the internal switch. When exposed to light, the photo eye turns off internal switch, and cuts power between black hot wire and red wire to light. When darkness is sensed by photo eye, the switch is turned on and power flows to light through red wire. Neutral wire completes the circuit.

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 Buy: Photo eyes at Amazon Resources: 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.
