What is THHN Wire

What is THHN Wire? THHN wire is an electrical wire with a thermoplastic insulator and a nylon jacket. It is known for its high resistance to heat and its many uses.

The PVC insulation and nylon jacket protect against abrasion, moisture, oil, chemicals, and sunlight.

THHN wire can withstand high temperatures both when it is dry and when it is wet. This makes it useful for a wide range of applications.

The nylon jacket also protects the wire from heat and wear, making it more durable and safe.

Uses of THHN Wire

THHN wire is often used for a wide range of electrical tasks such as:

  • wiring large appliances
  • service panels
  • lighting circuits
  • doorbells
  • general electrical wiring
  • building construction
  • vehicle wiring
  • commercial buildings.
  • grounding
  • bonding

In general, it can handle both high voltages and heavy currents. But to keep it safe, it should always be put in a conduit or raceway.
