The difference between 12/2, 14/2, and 16/2 landscape wire
12/2, 14/2, and 16/2 landscape wire are commonly used gauges for outdoor lighting. The number before the slash represents the wire gauge, while the number after the slash indicates the number of insulated wire conductors within the cable. For instance, 12/2 wire comprises 12-gauge wire with two insulated conductors, 14/2 wire has 14-gauge wire with two insulated conductors, and 16/2 wire consists of 16-gauge wire with two insulated conductors.
12/2 wire is suitable for longer cable runs and lighting systems with higher wattage, as it has a thicker gauge and can carry more current. On the other hand, 16/2 wire is ideal for shorter cable runs and low-wattage lighting systems.
As a general rule of thumb, the lower the gauge number, the thicker the wire and the more current it can carry.
Popular gauge sizes for outdoor lighting
In outdoor lighting applications, the most popular gauge sizes are 12/2, 14/2, and 16/2. These gauges are widely used due to their compatibility with different lighting setups and current-carrying capacities.
