The smaller the wire gauge number, the thicker the wire. Thicker wires have greater current carrying capacity.
Do not exceed 80% of your landscape wire current capacity to ensure there is no voltage drop.
Example: If the total wattage of your landscape lights is 40 watts, you can run 12 gauge wire for 200 feet without voltage drop.
Wirefy low voltage landscape wires are used for: outdoor accent lighting, landscape lighting, security lights, and outdoor specialty lighting applications not exceeding 30 volts. This wire can be exposed to direct sunlight, as well as be buried underground. It is intended to be used in temperatures min -4F to max 140F.
Wirefy landscape wire is crafted from 2 fully annealed bare stranded copper conductors and premium industrial-grade PVC insulation. Two wires are duplexed in a flat shape that allows for easy splitting during installation.
To make connections simply cut the wire to the desired length and strip the ends. Remember to allow slack in the wire running between lights, to that freeze/thaw cycles do not cause extensive tension on the wire. Waterproof wire nuts are recommended.
This is my third order of this item and the previous two have held up under ground in perfect condition.
