3 Awg THHN Building Wire

3 AWG single core THHN wire is perfect for circuits requiring significant current capacity. This wire uses high-quality copper conductors for superior electrical performance. It is sheathed in a heat-resistant PVC layer and protected by an outer nylon jacket, offering enhanced durability and resistance to environmental factors. Color options include white, yellow, orange, and brown.

Application

3 AWG THHN (Thermoplastic High Heat-resistant Nylon-coated) cable is a commonly used wire specification with large current carrying capacity and good heat resistance. It is suitable for power distribution systems within buildings. In industrial environments, it is widely used to connect various electrical equipment such as motors, generators and control panels, and can withstand high temperatures and current loads.

FAQ

1. Q: How many amps will 3 AWG wire carry?

A: 3 AWG THHN wire can carry up to 100 amps.

2. Q: What is 3 AWG wire used for?

A: 3 AWG wire is a versatile and heavy-duty electrical cable used in various applications due to its ability to handle significant electrical currents. Ideal for connecting high-current industrial equipment, such as large motors, generators, and transformers. And suitable for wiring large commercial lighting systems where high current is required.

3. Q: What is the ampacity of a #3 AWG copper conductor?

A:

The ampacity of a #3 AWG copper conductor can vary based on factors like insulation type, ambient temperature, and installation conditions.

For THHN Insulation: In a standard installation (such as in conduit or open air), a #3 AWG copper wire typically has an ampacity of 100 amps. This value assumes a temperature rating of 90°C (194°F) and standard installation conditions as per the National Electrical Code (NEC).
