THHN vs. THWN: Which Is The Better Building Wire?

WebTHHN wire has a voltage rating of 600V. It has a temperature range of up to 90°C in dry locations and 75°C in wet locations. This type of wire features either a bare copper or aluminum conductor and comes both stranded or solid, depending on the size. It is sometimes dual-listed as THHN/THWN wire. Shop THHN Wire How Do They Compare? WebThe “short-circuit current rating” is the maximum short-circuit current that a component can withstand. Failure to provide adequate protection may result in component destruction under short- circuit conditions. grey line background
