The term "16-gauge" typically refers to the thickness of metal or wire, commonly used in the context of shotgun barrels and electrical wiring. In shotguns, a 16-gauge barrel is larger than a 20-gauge but smaller than a 12-gauge, making it a versatile choice for hunting and sport shooting. It strikes a balance between recoil and shot capacity.
In electrical applications, 16-gauge wire is often used for various projects, including lighting and appliance connections. It is thicker than 18-gauge wire, allowing it to carry more current safely. This makes it suitable for moderate power needs in residential and commercial settings.
