Comparing wires to wires

XHHW Copper Conductor Wire VS XHHW Aluminum Conductor Wire

Today’s comparing segment will focus on comparing wires to wires, specifically wires of the same style but different conductor type. XHHW comes in a variety of conductor metals such as tinned copper, bare copper and also aluminum, believe it or not. And although many wires like these appear to be identical, specifications and configurations such as the interior metal conductors of copper or aluminum, have a significant impact on the success of the device or apparatus it will help power.

XHHW Wire, What Exactly Is It?

In the industry and market, XHHW can be considered among the most prominent in its class, helping power specifically the residential & commercial industry, hence the name building wire. According to the National Electrical Code (NEC), XHHW can be seen most typically used and applied as not only general purpose cabling & for distribution of power, but also for the wiring of branch circuitries in conduits and designated raceways.

XHHW building wire is considered to be a very versatile wire as its insulation and jacketing is not only resilient to water and extreme temperatures but also contains fire resistant material making it perfect for applications that requires element resistance. All XHHW wires are identical when it comes to jacketing and insulation, though the factor that differentiates the wires is the conductors as mentioned previously. Not only do theses wires that come in 10, 14 and 18 AWG have comparable volts ranging from 110V to 600V but also can endure up to 90 degree Celsius temp. In short, the fundamental distinctions in the wires are due to the properties of the conductors solely.

XHHW Copper Conductor Wiring

The copper metal is considered to be a metal substantial in weight, considerably more so than aluminum. Copper, as many of you might already know, is also much better of an electricity conductor making it the most valuable option.

XHHW Aluminum Conductor Wiring

On the other hand, aluminum conductors are much less substantial in weight, cost and conduction of electricity. Though one might immediately count aluminum conductors out of the race, that would be unwise. The two are incredibly helpful and adaptable in their specific environments, which is why knowing which conductor performs better in your specific application is extremely critical. At times an application might require less voltage and conduction of electricity, making aluminum conductors an excellent option. As this is said, and to prove a point, aluminum wires aren’t always permitted in applications where copper conductor wires are applied in, which is why it is critical you or your wire harness manufacturer is abiding by relevant regulatory laws.
