The pole height and flag size are key.
Landscape lighting wire requirements. 2-3 directional accent lights are often needed to illuminate the pole and the entire flag properly. Second you need to be able to distribute equal voltage to every single fixture in your landscape lighting system and that takes a well-planned wiring method. The 8 and 10 gauge wire is mainly used to extend the distance from the transformer to your first fixture on that run.
Do You Need a Special Transformer for LED. 16-gauge wiring can go as far as 3135 feet for one fixture at 15V. Make sure each cut end is 1 inch bare and the internal wires can be easily operated on.
As a general rule the thicker the wire lower gauge the less voltage will drop over long distances. Structures and wiring. 12 and 14 gauge wire seem to be common for most projects.
When wiring landscape lights determining voltage drop is very important so you dont have dim lights at the end of your run. This beam spread is also ideal for general accent lighting. Besides it should also match electrical circuit amperage.
When it comes to gauge its not an exact science. This is simply a 12 to 24 length of wire coiled at the base of each fixture. 25 - 45 degrees for medium height and width such as a prized tree.
Then work on stretching the wire out completely. Wire needs to be buried a minimum of 6 inches deep and 24 inches deep under driveways and sidewalks. Once you are done move on fixing the spot where youll be making a cut.
