5 Minutes to Know Advantages and Disadvantages of THHN Wires

In building construction, many workers have used THHN wires. Is this because THHN stranded wires belong to building cables? Actually, THHN stands for Thermoplastic High Heat Resistant Nylon Coating. This refers to the properties of the insulating material that protects the wire. In most cases, THHN wire is rated for application voltages up to 600 volts and environments where temperatures do not exceed 194 degrees Fahrenheit. But THHN wire is not suitable for very humid locations. Let's discuss the advantages and disadvantages of THHN wires!

THHN wire advantages and disadvantages

 
There are many reasons why THHN wire is widely used in commercial electrical installations. However, this is not the answer for all wiring situations. These advantages and disadvantages of THHN wire must be considered in your planning.

Advantages of THHN Wire

1. The PVC and vinyl insulation on the THHN wire makes it easy to run through the conduit. In applications requiring conduit run to meet building codes, the ability to pull large cable bundles through installed conduit is critical.

2. THHN wiring is almost universally accepted by building codes across the United States. In some cases, this makes your project planning easier.

3. THHN is suitable for high temperature areas. In most cases, THHN wire can be used where the temperature is kept below 90 degrees Celsius.
 
4. THHN wires are the backbone of most wire installations. Popular in home wiring as permitted in building and electrical codes.

Disadvantages of THHN Wire

The main disadvantage of THNN wire is that it requires various conduits to be installed in proper conduit or cable tray for wiring. Installing conduit adds installation costs. Proper installation of conduit requires special skills and tools, which add additional costs.
 
In the United States, nearly all building codes require circuits in commercial buildings to run in conduit. When wires must be enclosed in wire conduit, so most electricians choose THHN wire.

 
Summarize
 

THHN wire can be laid in a high temperature environment up to 90 degrees with its own thermoplastic high heat-resistant nylon coating, and has won the favor of the majority of electricians with its own advantages; in terms of shortcomings, it just meets the requirements of the American building code. The way of laying thhn wires in conduits has also won the love of American construction, so thhn wires are widely used regardless of their advantages or disadvantages.
