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

armored cable
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.

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

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.

d) Check tabs or pins are set, and manually rotate dial
f) Check override switch is pushed fully in position
g) Move override lever to different positions and manually rotate dial
h) Try timer in different plug and with different lamp
j) Test circuit with inexpensive circuit analyzer from hardware. Reversed polarity (incorrect wiring on outlet) can affect some timers and affect electronics. Buy circuit analyzer

k) Don't exceed maximum wattage rating. Refer to product manual, or product label.
l) some timers are not rated for motors, or LED, CFL, fluorescent etc bulbs... check rating
m) Check Hz or cycles rating of timer. US and Americas use 60 Hz, while Europe and Asia uses 50 Hz

b) Turn photo eye away from light source, outdoor lights, street lights, passing cars, reflected light off siding
c) Always plug into grounded GFCI-protected outlet. Do not use 2 GFCI on same outlet.
d) Check outlet for power. Turn breaker fully off and then back on.
e) Check outlet polarity with with circuit analyzer Buy circuit analyzer
f) Check that lights work... plug lights directly into outlet without using timer
g) Do not let snow accumulate over top of timer
h) Do not exceed watt rating shown in product manual
i) Check if timer is rated for type of bulb being used
j) Power surge, power outage, nearby lightning strike can knock out timer permanently. Install surge protector.

Basic house wiring
Add black tape when White wire carries voltage (applies to 208 and 240V circuits)
With 120 and 277 Volt circuits, White wire is Neutral, and Black is Hot
With 208 and 240 circuits, both wires are Hot, and both wires carry voltage
Black tape on White wire identifies wire is Hot and not Neutral
