Install this copper wire in conduit and cable trays in commercial and industrial buildings. It's also known as branch circuit wire. The outer jacket is designed to be installed without applying pulling lubricant.
Stranded wire is flexible, so it’s pliable enough to be pulled around corners. Wire with a nylon outer insulation resists oil and water. TFFN wire is also known as fixture wire. It’s for use in dry locations.
