This product, available at a major home improvement retailer, refers to a type of electrical cable containing four conductors, each with a 10 American Wire Gauge (AWG) thickness. It is commonly utilized for high-power applications, such as supplying electricity to electric ranges, dryers, or subpanels. For instance, a homeowner might employ this cable to run a dedicated circuit from their main electrical panel to a workshop requiring substantial power.
Its significance lies in its ability to safely and efficiently carry a substantial electrical load. The four conductors include two hot wires, a neutral wire, and a ground wire, providing a complete circuit for the intended appliance or electrical system. Prior to the widespread adoption of modern wiring standards, similar, though perhaps less standardized, cabling was necessary for operating high-demand electrical appliances in residential and commercial settings. The availability of this specific cable at a large retailer indicates a common need for robust electrical solutions within the consumer market.
The following sections will delve deeper into the specific applications, safety considerations, installation guidelines, and alternative wiring options relevant to high-amperage electrical circuits. This information is intended to provide a comprehensive understanding of its use and proper implementation.
1. Amperage capacity
The amperage capacity of this cable is a critical determinant of its suitable applications. It defines the maximum safe current, measured in amperes, that the cable can continuously conduct without overheating and potentially causing a fire. A 10/4 cable, constructed with 10 AWG conductors, typically possesses an amperage capacity dictated by the National Electrical Code (NEC), which varies depending on the conductor’s insulation type (e.g., THHN, THWN). Exceeding this capacity poses a significant risk of thermal overload, compromising the integrity of the wiring and potentially initiating a fire.
For example, if the specifications for a specific 10/4 cable list a maximum amperage of 30 amps, using it to power an appliance demanding 40 amps would constitute a serious safety violation. The resulting overheating could melt the insulation, creating a short circuit and posing a fire hazard. Understanding the amperage requirements of the intended load is therefore paramount before selecting and installing electrical wiring. Appliances like electric ranges and dryers often require circuits capable of handling significant amperage, making 10/4 wire a common, though not always the only, option for these applications.
In conclusion, the amperage capacity of this cable is an inherent characteristic that directly dictates its application safety. It is imperative that electrical installations strictly adhere to NEC guidelines and manufacturer specifications to ensure that the current draw of connected devices remains within the cable’s safe operating parameters. Failure to do so can have severe and potentially life-threatening consequences.
2. Voltage rating
The voltage rating of this cable is a fundamental specification dictating its safe operational limits within an electrical system. It defines the maximum electrical potential difference the cable’s insulation can withstand without risking breakdown or electrical arcing. Exceeding this rating can compromise the insulation, leading to short circuits, electrical fires, and potential equipment damage. The voltage rating is not the voltage that is present in the wire, but rather the maximum sustained voltage the wire can tolerate.
-
Standard Voltage Rating for Residential Applications
This cable typically carries a voltage rating of 600 volts, aligning with the standard voltage used in most residential electrical systems in North America (120/240 volts). This rating provides a safety margin, ensuring the cable can reliably operate under normal conditions and withstand transient voltage spikes without insulation failure. Using a cable with a lower voltage rating in a standard residential application would pose a significant safety risk.
-
Impact on Application Suitability
The voltage rating restricts the types of circuits where this cable can be safely employed. Its suitability for powering high-voltage appliances like electric ranges and dryers stems from this 600-volt rating. It would be inappropriate for use in higher voltage industrial applications. Matching the cable’s voltage rating to the circuit’s operating voltage is paramount for safe and reliable electrical installations.

A copper conductor in 10/4 wire ensures the cable can handle the amperage load specified for its gauge without excessive heat generation, which is critical for safety. For instance, a copper 10 AWG conductor typically supports up to 30 amps, depending on insulation type and installation conditions.
-
Aluminum Alternatives and Trade-offs
While less common in this particular type of wiring due to code restrictions and performance limitations, aluminum is sometimes used as a conductor material in larger gauge wires or in specific applications. However, aluminum has a lower conductivity than copper, necessitating a larger gauge wire to carry the same amount of current. Furthermore, aluminum is more prone to oxidation, requiring specialized connectors and installation techniques to prevent connection failures. Using aluminum in place of copper in a 10/4 configuration is generally not advisable and may violate electrical codes.
-
Purity and Grade of Conductor
The purity and grade of the copper conductor also influence the cable’s performance. High-purity copper (e.g., 99.9% pure) exhibits lower resistance and better overall conductivity. The presence of impurities can increase resistance and reduce the cable’s ability to efficiently carry current. A higher grade of copper in 10/4 wire contributes to a more reliable and energy-efficient electrical circuit, extending the lifespan of the cable and connected devices.
-
Stranding and Flexibility
The conductor may consist of a single solid wire or multiple strands of thinner wire bundled together. Stranded conductors offer greater flexibility, making the cable easier to install and route, especially in tight spaces. This wire typically employs a stranded conductor for enhanced flexibility, improving the ease of installation in residential wiring applications. The number and gauge of the individual strands affect the overall flexibility and current-carrying capacity of the cable.
In summary, the copper conductor material in this cable plays a vital role in its ability to safely and efficiently deliver electrical power. The conductivity, purity, and stranding of the copper all contribute to the cable’s overall performance and suitability for its intended applications. Substituting aluminum or using lower-grade materials can compromise the cable’s safety and reliability, underscoring the importance of using high-quality copper conductors in electrical wiring.
