What is #2 Thhn good for?
APPLICATION: Copper THHN/THWN-2 conductors are primarily used in conduit and cable trays, when approved, for services, feeders and branch circuits in commercial or industrial applications as specified in the National Electric Code.
Is Southwire Thhn dual rated?
That wire is actually dual rated as THHN and THWN, and the jacket will be stamped with both.
What does Thhn 2 mean?
Thermoplastic High Heat-resistant Nylon-coated
THHN stands for “Thermoplastic High Heat-resistant Nylon-coated”. THWN-THHN-2 wire is one of the most common single conductor wires used in the United States. Most wires in this category carry a dual rating and are marked and approved for both applications.
What does the 2 mean in Thhn 2?
THWN-2 Cable The THWN wire we carry is actually coded THWN-2 indicating its rated 90 degrees for both wet or dry locations which is even better.
What is the difference between Thhn and Thhn 2?
The main difference between these two standards is their maximum temperature in wet locations. THWN has a maximum temperature of 90°C in dry and wet locations, whereas THHN wire can only be used in temperatures as high as 75°C in wet locations. However, most of these wires, so you can use THHN and THWN interchangeably.
How many amps is #2 Thhn good for?
Allowable Ampacities of Insulated Copper Conductors

What is SIMpull wire used for?
Southwire® SIMpull THHN® copper conductors are primarily used in conduit and cable trays for services, feeders and branch circuits in commercial or industrial applications as specified in the National Electrical Code.
What’s the difference between Thhn and THWN 2?
Is Thhn the same as AWG?
THHN wire is typically snaked through interior walls and is never used outside. It’s one of the most common wires of its type and is often used quickly and effectively by contractors for permanent electrical work. 6 AWG is much more versatile, however.
Is THWN and THWN 2 the same?
Both THHN and THWN wires are used in a variety of installations. Thermoplastic high-heat resistant nylon-coated wire, or THHN, is a common wire used for connecting branch circuits and appliances. Its counterpart is called THWN (or THWN-2).
What is #2 wire rated for?
Wire Size and Amp Ratings
| Wire Size | 60°C (140°F) | |
|---|---|---|
| AWG | (mm²) | Copper |
| 4 | (21.2) | 70 |
| 3 | (26.7) | 85 |
| 2 | (33.6) | 95 |
What is Type THWN 2 insulation?
THHN/THWN-2 is a thermoplastic product. It uses a thinner PVC insulation, which can lead to current leakage and dielectric breakdown in demanding circuits or from chemical or environmental exposure. The PVC insulation in THHN/THWN-2 emits a toxic smoke when burned and is less flexible at cold temperatures.
Which is better AWG or Thhn?
Usage. THHN wire is typically snaked through interior walls and is never used outside. It’s one of the most common wires of its type and is often used quickly and effectively by contractors for permanent electrical work. 6 AWG is much more versatile, however.
Can Thhn wire be used in outdoor conduit?
THHN (Thermoplastic High Heat-resistant Nylon-coated) wire is designed with a PVC (polyvinyl chloride) insulated nylon sheath. Most THHN building wire comes with the dual rating THHN/THWN, meaning it is usable in both wet and dry conditions, as well as both indoor and outdoor use.
