3/0 Gauge Copper Wire: Understanding Its Applications and Uses
What is 3/0 Gauge Copper Wire?
3/0 gauge copper wire, also known as "000" or "triple ought" wire, is a type of electrical wire that is widely used in various industrial, commercial, and residential applications. The "3/0" designation refers to the wire's American Wire Gauge (AWG) size, which indicates its diameter and conducting capacity.
Physical Characteristics
3/0 gauge copper wire has a diameter of approximately 0.4096 inches (10.4 mm) and a cross-sectional area of 211,600 circular mils. It is a heavy-gauge wire that is typically insulated with a durable material, such as XLPE (cross-linked polyethylene) or EPR (ethylene propylene rubber), to protect it from environmental factors and mechanical damage.
Electrical Properties
3/0 gauge copper wire has an ampacity rating of up to 200 amps, depending on the specific application and environmental conditions. It has a relatively low resistance of 0.077 ohms per 1000 feet, making it suitable for high-current applications.
Applications and Uses
3/0 gauge copper wire is commonly used in a variety of applications, including:
Electrical Power Distribution
- Feeder circuits in commercial and industrial buildings
- Service entrance wires for electrical power distribution systems
- Underground electrical cables for utility and residential applications
