Both type thwn-2 and type <u>THHN </u>conductors have an insulation temperature rating of 90 degrees celsius and generally meet the temperature requirement for connecting luminaires.
<h3>What is the difference between THHN and XHHW conductors?</h3>
The wire's jacket is the primary distinction between THHN/THWN/THWN-2 and XHHW/XHHW-2 and. The THHN family's jacket is thinner, thus even while more THHN can fit through a variety of barriers, it doesn't provide as much protection as the XHHW jacket. Additionally, the coating on the jacket of the XHHW is more resistant to chemicals, ozone, and abrasions, whereas the thinner coating on the THHN, when exposed to harsh chemicals or the environment, can cause current leakage and eventually degrade, releasing hazardous smoke when burnt.
As always, performance against budget must be taken into consideration when deciding whether to use THHN or XHHW. THHN wire is ideal for their requirements. However, XHHW has the extra characteristics that offer greater effectiveness and longer durability.
