Building Wire

(Results: 198 Found; Refine your results by making selections from the menu)


Whenever a consumer or builder is tasked with the planning or construction of a building or the use of an appliance for these purposes, it is vital to understand the advantages of certain wire types over others. We sell wire and cable in dozens of categories, including Building Wire, with a significant number of attributes that can be selected on our site menu to narrow down the most suitable choices even further.

Two major categories of Building Wire offered through our manufacturers Houston Wire & Cable, Priority Wire & Cable, Alan Wire, Nexans Energy USA, and Omni Cable are Thermoplastic High Heat-resistant Nylon coated (THHN) and Cross-linked High Heat-resistant Water-resistant (XHHW).  While the former is commonly seen being used in machine tool, appliance, and control circuit applications, XHHW is utilized in other sorts of residential, commercial and industrial settings, including raceways and feeder wiring.

What is THHN?
THHN Building Wire is available in configurations with two different types of conductor, either solid or stranded. The material used is also either aluminum or copper dependent on the application, with a nylon jacketing material and an insulation generally made with polyvinyl chloride (PVC). The nylon jacket this building wire type reduces the level of needed insulation, a feature which allows the conduit it’s installed in to hold more wires within an installation. This is a great asset to have when using conduit systems that are either underfloor or that have a built-in installation.

In addition to the protection this nylon offers for mechanical purposes, it also acts as a buffer to prevent wire abrasion from these devices coming into constant contact with conduit. Jacketing in particular helps Building Wire to resist the effects of other things like grease, gasoline, and oil.

Building Wire from manufacturers like Alan Wire, Nexans Energy USA, Priority, Houston, and several others has received rating approval for 600 volts maximum and has been UL listed for use in dry locations up to 90 degrees Celsius and in wet conditions up to 75 degrees Celsius. Those THHN wires that carry a dual rating are suitable for being used in wet applications as well as dry ones.

What Makes XHHW Wire Different?
XHHW Building Wire represents a step above THHN for a couple of important reasons. First, XHHW wire has a thicker insulation made of XLPE material, rather than the PVC commonly utilized for THHN wire. A greater amount of coating material also cuts down on material breakdown from regular exposure to various elements and helps prevent leaking. Second, XHHW building wire has an increased amount of flexibility compared with THHN because of its non-nylon coating. This more flexible coating can make it very desirable for trickier types of projects.

As a result of these differences, XHHW is costlier for installers and consumers than THHN. For certain applications, however, the cost difference is certainly worth it. If THHN is utilized in an inappropriate application that results in higher-than-desired heat, the coating on this wire will actually emit a highly unsafe and toxic smoke.

All in all, while XHHW wire does carry these important benefits over the other, it is also outside of the budgetary limits of many engineers and the projects they are working on. We always suggest getting in touch with OneStopBuy’s customer service and technical support team by way of phone, email, or live chat in order to discuss your particular application needs, as well as important budget considerations. We will help you find the wire products that can best serve these requirements.
