  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.

 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.

Why
is this timer a photo eye? Because it can operate dawn-to-dusk or dusk-to-dawn. The timer automatically adjusts for time zone. The dawn dusk setting can be adjusted slightly longer or shorter. The timer can be connected to delay timer to turn off earlier than dusk or dawn Choose dawn-to-dusk by connecting blue and red wire together. Choose dusk-to-dawn by capping red wire Why is this timer 24 Volt DC Because the timer is battery-operated. Battery lasts 2-3 years. Because the timer does not need to be connected to 120 Volt AC or 240 Volt AC power to operate. Just the battery is needed Timer can be located inside electric box, anywhere outdoors-or-indoors. Can be located in shaded or dark location without affecting operation. ST01 timer is rated DC Loads 4A 12V dc, 2A 28V dc Resources: How to program and wire ST01 timer |

Use DC timer to control solar water heater How it works: When water inside tank is cold, then lower thermostat turns ON 12-24 Volt power supply provides electricity to lower thermostat Thermostat turns ON, then DC relay turns ON, letting solar power flow to lower element. At same time, power is sent to ST01 timer, waiting for timer programs to activate ST01 is battery powered, and keeps time and will operate relays even is 12-24 VDC does not arrive from lower thermostat. With this specific illustration, the lower thermostat must be ON before 12-24 VDC travels to ST01 timer When timer is ON, and lower thermostat is ON, then timer turns ON upper element When solar power is not full strength, then you want to activate lower watt, higher-resistance element to maximize solar output. In this illustration, the lower watt element is the upper element on water heater Set timer so it is ON from 6 AM to 10 AM Set timer so it is OFF from 10 AM to 3 PM Set timer so it is ON from 3 PM to 9 PM Resources: Convert AC water heater to DC water heater |

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 |
