Underground cables are laid out from the house to the outdoor fixtures by the shortest route possible to reduce the length of trenches.
GFCI receptacle is positioned near the start of the cable run and is wired to protect all wires to the end of the circuit.
Motion-sensor security light is positioned so it has a good "view" of entryways to the yard and home, and is aimed so it will not shine into neighboring yards.
Manual override switch for motion-sensor light is installed at a convenient indoor location. Override switches are usually mounted near a door or window.
Entry point for circuit is chosen so there is easy access to the circuit breaker panel. Basement rim joists or garage walls make good entry points for an outdoor circuit.
Yard obstacles, like sidewalks and underground gas and electrical lines, are clearly marked as an aid to laying out cable runs.
Check for underground utilities when planning trenches for underground cable runs. Avoid lawn sprinkler pipes, and consult your electric utility office, phone company gas and water department, and cable television vendor for the exact locations of underground utility lines Many utility companies send field representatives to show homeowners how to avoid dangerous underground hazards
