What is Thhn wire rated for?
THHN is a code for thermoplastic high heat resistant nylon coated wire which is allowed for use in dry to damp location and rated for a maximum temperature of 90ºC (194ºF).
How many amps can Thhn wire handle?
Wire Size & Amp Ratings
| Copper | ||
|---|---|---|
| Wire Gauge Size | 60°C (140°F) NM-B, UF-B | 90°C (194°F) THWN-2, THHN, XHHW-2, USE-2 |
| 14 | 15 | 25 |

What gauge is Thhn wire?
THHN Conductor Materials THHN wires with a smaller diameter between 10 and 14 American Wire Gauge (AWG) have solid, soft-drawn, copper conductors. Larger THHN wires have stranded copper conductors.
What is the difference between AWG and THHN wire?
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.
Is all THHN dual rated?
The majority of THHN wire carries a dual rating on the cable marked THHN / THWN for both the wet and dry temperature rating.
What is #12 THHN wire used for?
general purpose wiring
12 thhn solid wire is 1/2.0mm. #12 thhn stranded wire is 7/0.6mm. These cables are rated at 600 volts and have a load capacity of 20 at 90°C. #12 THHN wire is used for general purpose wiring installed in conduit or other recognized raceways for new construction as defined by the National Electrical Code (NEC).
Is Thhn and AWG the same?
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 Thhn wire rated for outdoor use?
What Wire and Cable Should Be Used Outdoors? THHN is still the single conductor wire used outdoors and in conduit, because the THWN rating can resist water, oil, gases, and solvents.
What is THHN wire rated for?
THHN / THWN / THWN-2. THHN wire is approved for up to 600V and is listed by Underwriters Laboratory (UL), as rated for 90° C (194° F) in dry and 75° C (167° F) in wet environments. THHN wire comes with a dual rating: THHN / THWN, which means it’s appropriate for both dry and wet applications.
What are the advantages of using THHN building wire?
THHN’s relatively thin PVC insulation improves conductivity but reduces the flexibility of the wire. By using THHN in a cable bundle, it can minimize the disadvantage of inflexibility. To ensure safety between construction workers and running electrical equipment, THHN building wire can be bundled to fit the specifications of the worksite.
What is the difference between jacketing protection and THHN wire?
The jacketing protection is abrasion resistance but has little else in means of wire protection. THHN electrical wire is meant for use as general-purpose wiring for installation in conduit or other recognized raceway. THHN wire may also be used for machine tool, appliance, and control circuit wiring.
What is THHN wire made of?
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.
