16 AWG PVC Hook Up Wire With Nylon

Getting a 16 AWG hook up wire with a nylon coating shouldn’t be that difficult because there are many wire and cable suppliers that offer TFFN products. Southwire is one of the biggest manufacturers of TFFN wire which is available in 16 AWG and has the nylon coating.

1. TFFN = Thermoplastic Flexible Fixture Nylon

2. THHN = Thermoplastic High Heat Nylon

3. THWN = Thermoplastic Heat and Water resistant Nylon

The acronyms above each have specific letters that represent specific characteristics of the particular wire you’re looking to buy. If the “N” is missing from the acronym (THW wire) then the nylon coating will be missing as well. Since the beginning of the 2000’s these types of electrical wire have been dual or tri-rated in order to minimize inventory for large manufacturers. You’ll commonly find an electrical wire with THHN/THWN/THW markings on it which means all of the approvals above have been met in the same wire. It can be called a universal THHN wire.

The nylon coating adds value to the wire in a few ways starting with the resistance of moisture, chemicals, oils and solvents. It’s also a glossy smooth finish helping with the installation process. The nylon coating almost provides a lubricant which helps it slide through the conduit installations.

THHN and THWN electrical wires are used in homes and buildings to run power from the electrical box to the lights, outlets and appliances. You might even see the THHN wires within a cable format in such cables as MC cable, Romex® NMB cable and UFB underground cables. Each cable has a different jacket over the wires to protect it against the environment it is most commonly used in. UFB is the most expensive cable with the highest amount of engineering to protect the copper from direct burial use.

Underneath the nylon coating is a thermoplastic, or PVC, insulation. PVC is a common type of insulation for electronic and appliance wire used indoors. UL1015 16 AWG hook up wire is a standard type that’s cut to length and used in wire harnesses that are then used in appliances to make multiple connections at once. There are many colors available for harnesses that require 15 to 20 wires in it.

Speak to your wire and cable supplier to see which type of wire is best for your application. They will provide you with some insight about each type of hook up wire for you to make the final decision.
