Beside this, what does the 2 in THWN 2 stand for?
THWN-THHN-2 Wire. 22nd Oct 2015. THWN stands for Thermoplastic Heat and Water-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.
What is the difference between Thhn and XHHW wire?
THHN/THWN The main difference between these two building wires is that XHHW-2 features XLPE insulation and THHN/THWN uses PVC. However, when burned, PVC can emit toxic smoke, and because THHN/THWN is designed with a thinner PVC insulation, it is more susceptible to current leakage and eventual breakdown.
