    Leave a Comment
    Click to ExpandParalleled Cables

    Parallel or paralleled cables are a configuration where multiple cables are combined. Parallels are used to make cable installation easier, since only one reel needs to be set up for installation, rather than one reel per cable.

    This article will explore the basics of paralleled cables, examining their configuration and the products that can be utilized in a similar setup.

    How Paralleled Cables Work

    Paralleled cables work by combining multiple individual wires into a single bundled configuration. This involves taking up to four separate cables and winding them onto a single reel to create a consolidated assembly. The wires are typically selected based on their intended application and requirements.

    The cables are meticulously arranged side by side and then wound together. This process ensures that the components maintain a consistent orientation and are securely held together. Proper organization and management of the bundled cables also prevent tangling, reduce signal interference, and facilitate easier installation and maintenance.

    Paralleled cables offer several advantages over using individual ones. First, they help reduce clutter, making installations more manageable. Second, the configuration reduces the risk of cable damage and abrasion, as the elements are less likely to become tangled or snagged. This configuration allows for streamlined routing and easier identification of specific cables within the bundle. Lastly, parallels reduce  installation time resulting in reduced labor costs.

    Common Products for Parallel Configuration

    Paralleling the following products allows for an increase in overall ampacity, enabling the transmission of higher electrical currents while ensuring optimal performance:

    Cross-Linked High Heat Water-Resistant (XHHW-2) Cables

    XHHW-2 cables feature cross-linked polyethylene (XLPE) insulation, which provides excellent thermal stability and heat resistance. This material allows them to handle higher operating temperatures than traditional thermoplastic insulators. They are also engineered to be water-resistant, protecting them from moisture and environmental conditions.

    These components are available in various sizes and voltage ratings to accommodate different installation requirements. They are often used in motor wiring, lighting fixtures, control systems, and applications where reliable and efficient electrical connectivity is essential. Furthermore, suitable connectors and proper bending radii are critical during installation to prevent system damage.

    Paralleling XHHW-2 cables enables them to be used in the following applications:

    • Data centers
    • Industrial settings
    • Large-scale commercial installations
    • Manufacturing facilities
    • Oil and gas refineries
    • Power plants

    Thermoplastic High Heat Resistant Nylon (THHN) Cables

    THHN cables use thermoplastic polyvinyl chloride (PVC) insulation, which offers good electrical insulation and resistance to moisture, chemicals, and abrasion. They also have a nylon outer jacket to increase their durability and heat endurance. Thus, they are rated for applications with temperatures reaching 90°C (194°F).

    These cables come in various wire sizes or gauges, ranging from 14 American Wire Gauge (AWG) to thousand circular mils (MCM). This size determines the cable’s current-carrying capacity, with larger ones capable of carrying higher currents. The conductor’s insulation is also color-coded, with commonly used colors including black, white, red, green, and blue.

    The size or gauge of the paralleled THHN cables must be the same to ensure even current distribution. Each cable’s length in the parallel arrangement should also be equal to minimize resistance and current flow imbalances. Here are some of the common applications of paralleled THHN cables:

    • Data centers
    • Electric vehicle charging stations
    • High-capacity power distribution systems
    • High-power lighting systems
    • Industrial machinery
    • Large electrical motors

  2. What To Look For in XHHW-2 Cables

    Leave a Comment

    XHHW-2 is an acronym for XLPE (cross-linked polyethylene) High Heat-resistant Water-resistant. These cables are designed to withstand high temperatures and harsh environments and are commonly used for power distribution, lighting, and control circuits. Moreover, their excellent thermal and electrical properties make XHHW-2 cables a reliable choice for a wide range of industrial and commercial applications.

    To choose the right XHHW-2 cable for your needs, it’s essential to understand its features and specifications. This article will delve into the important aspects of XHHW-2 cables that you must consider when choosing the right cable for your application.

    Key Factors To Consider When Selecting XHHW-2 Cables

    The following are the key considerations when selecting XHHW-2 cables:

    Ampacity

    The ampacity is determined by the size of the cable’s conductor and the type of insulation used. When selecting an XHHW-2 cable, it is important to consider the ampacity rating based on the amount of current that your specific application requires.

    Voltage Rating

    The voltage rating of an XHHW-2 cable refers to the maximum voltage at which the cable can operate safely. It’s essential to choose a cable with a voltage rating that meets or exceeds the requirements of your specific application. Failure to do so could result in safety hazards and equipment damage.

    Conductor Size

    The conductor size determines the amount of electrical current the cable can safely carry. Choosing a cable with a conductor size that’s too small for your application could result in overheating and potential risks.

    Insulation Material

    The insulation material of an XHHW-2 cable plays a vital role in protecting the conductor from damage and ensuring the cable’s durability. XLPE is the insulation material for XHHW-2 cables due to its excellent electrical properties and resistance to heat and moisture.

    Temperature Rating

    The temperature rating of a cable refers to the maximum temperature at which the cable can safely operate without deteriorating or melting. For example, XHHW-2 cables typically have temperature ratings of 75 °C, 90 °C, or 110 °C.

    If the cable is exposed to higher temperatures than its rating, it can become damaged and fail, leading to costly downtime and potentially hazardous situations. On the other hand, choosing a cable with a lower temperature rating than necessary can result in inefficiencies and reduced performance.

    Cable Tray (CT) Marking

    There are many building wire installations where single conductors, such as XHHW-2 are used. The NEC (National Electrical Code) Article 392 recognizes single conductor cables for use in cable trays (CT) where the conductor is marked “CT” or more commonly, “FOR CT USE”.

    Not all manufacturers offer XHHW-2 with the CT marking, as this marking is optional under UL 44 and UL 83. Many distributors and contractors assume all XHHW-2 is the same, however, it is not. All Classic Wire XHHW-2, sized 1/0 AWG and larger, are marked “FOR CT USE”.

    REQUIREMENTS
    There are a few requirements that the single conductor must satisfy in order to be marked for use in cable tray (CT):

    1. The single conductor must be a circuit conductor sized 1/0 AWG or larger, or an equipment grounding conductor sized 4 AWG or larger; and
    2. Flame tested using the vertical-tray flame test (“Method 1 – vertical tray” in UL 2556), or the FT4 vertical-tray flame test (“Method 2 – FT4” in UL 2556).

    Applications of XHHW-2 Cables

    Here are some of the most common applications of XHHW-2 cables in industrial and commercial projects:

    • Power distribution
    • Motor connections
    • Lighting
    • Control wiring
    • HVAC systems

    Ensuring a reliable and efficient supply of electricity to residential and commercial properties hinges on service entrance cables. This cable is the conduit through which electrical power is transported from the utility pole to the primary electrical panel. It also acts as a protective shield, securing the electrical wiring from external elements, such as extreme temperatures and physical damage.

    This article will explore the importance of service entrance cables, their different types, and their installation process.

    What Are Service Entrance Cables?

    A service entrance cable is the link between the power line provided by the utility company and the main electrical panel. It is typically constructed using aluminum or copper, two highly conductive metals that facilitate efficient electricity transmission.

    Since the cable is often exposed to outdoor conditions, it is engineered to withstand the elements. Therefore, it is usually insulated and jacketed to protect against moisture, sunlight, temperature variations, and physical damage. The insulation and jacketing materials used in its construction also provide a protective barrier, ensuring the longevity and durability of the cable.

    Types of Service Entrance Cables and Their Installation Processes

    Three main types of service entrance cables are commonly used in electrical installations. Here is an overview of each:

    Overhead Service Entrance Cable

    An overhead service entrance cable is intended for installations where the utility lines are suspended above the ground. This cable is typically used in areas where power lines are mounted on poles or other structures. One of its features is its aerial installation, where the cable is suspended from utility poles or other support structures.

    This cable is available in various sizes and configurations to accommodate power requirements and local electrical code regulations. It is typically made of aluminum or copper, both known for their excellent conductivity properties. Nonetheless, the choice of conductor material depends on factors such as electrical load, cost considerations, and local regulations.

    Underground Service Entrance Cable

    An underground service entrance cable is specifically designed for electrical installations where the utility lines are buried underground. It is commonly used in areas where the power lines are routed beneath the surface to provide electricity to residential or commercial buildings. It is also laid in trenches or conduits, ensuring they remain shielded and secured from external elements and accidental damage.

    The use of this cable offers several advantages. First, it eliminates the visual impact of overhead power lines, providing a more aesthetically pleasing environment. Second, it reduces the risk of outages caused by adverse weather conditions, such as high winds, which can affect overhead power lines.

    Combination Service Entrance Cable

    A combination or duplex service entrance cable combines overhead and underground configurations into one assembly. This versatile and customizable cable is intended for overhead-to-underground power line transition properties. It simplifies the installation process and reduces potential points of failure, ensuring an efficient power supply.

    It is important to note that a combination service entrance cable should adhere to local electrical code regulations and specifications. In addition, proper installation techniques should be employed to ensure safe and compliant electrical connections for properties with mixed overhead and underground power lines.

    Leave a Comment
    Click to ExpandCopper-to-Aluminum-Conversion

    The cost of cables has increased due to the steady rise in copper prices in recent years. As a result, many customers are searching for alternatives to reduce expenses without compromising the quality of their assemblies. Using aluminum conductors instead of copper is one such option.

    Although Copper and Aluminum exhibit some notable contrasts, they also share similarities that make them suitable for comparable uses. Thus, customers can save money on their projects by switching to aluminum conductors.

    At Classic Wire & Cable, we offer a range of aluminum conductors suitable for various applications. Our engineering team can work with customers to select the right cable. We carry THHN, XHHW-2, RHW-2, and USE-2, SER, SEU, URD, MC products, all available in aluminum.

    Using the Ampacity Conversion Chart

    Suppose you are considering switching from copper to aluminum conductors to save money on your electrical project. This can be done using the ampacity conversion chart provided by the National Electric Code (NEC) 310.15(B)(16) 2017.

    The chart lists the ampacity ratings for different sizes of aluminum conductors based on an ambient temperature of 30 °C. The dimensions are listed in AWG or square millimeters, and the ampacity ratings are listed in amperes (A). To use the chart, locate the size of the copper conductor you would normally use and find the corresponding ampacity rating. Then, find the size of the aluminum conductor with a similar ampacity rating.

    Why Aluminum Can Be a Cost-Effective Alternative to Copper

    Weight and Cost Savings

    Aluminum’s lighter weight compared to copper results in substantial savings in transportation and installation costs. Due to its lower density, a larger quantity of aluminum can achieve the same electrical conductivity level while decreasing the overall product weight. Consequently, expenses for shipping and labor during installation are also reduced.

    Conductivity Considerations

    One way to offset aluminum’s lower conductivity is by designing conductors with larger cross-sectional areas. This approach can decrease resistance and enhance conductivity, improving overall performance.

    Corrosion Resistance

    Copper and aluminum are corrosion-resistant metals, making them suitable for usage in tough environmental conditions. Nonetheless, aluminum is better equipped to handle corrosive surroundings due to its ability to create a protective oxide layer upon exposure to the atmosphere. This layer helps to prevent further corrosion, ultimately extending the lifespan of the aluminum conductor.

    Click to ExpandType-MC-Armored-Cables” data-lazy-src=

    Also known as metallic sheathed cables, metal-clad (Type MC) armored cables consist of one or more insulated circuit conductors. The cable is usually protected by an aluminum or steel interlocking tape armor, or a smooth aluminum corrugated sheath.

    The aluminum interlocked armor, widely used with Type MC cables, acts as mechanical protection for electrical circuits. With over 200 years of combined experience, Classic Wire & Cable is a trusted supplier of aluminum conductor Type MC armored cables for electrical distributors.

    Uses of Type MC Armored Cables

    Though Type MC and Type AC cables bear a resemblance, the two should not be confused. Type AC cables are manufactured with an internal bonding strip, while Type MC cables have an equipment ground conductor (EGC). Due to these unique features, Type AC cables are not permitted in outdoor environments, specifically in damp areas while Type MC cables are suitable for both indoor and outdoor use.

    However, it’s important to note that you should not install Type MC cables in areas where they are likely to be physically damaged. You must secure and support them at no more than six-foot intervals. Consult Article 330 in the National Electrical Code (NEC) for more information.

    Common applications of Type MC cables include:

    • Service entrance cables
    • Feeders or branch circuits for power and lighting circuits
    • Control cables
    • Flexible, protected whips to HVAC equipment, light fixtures, or other wiring methods and equipment

  7. What Is a Service Entrance Cable?

    Leave a Comment

    Service entrance cables are electrical cables that connect and carry electrical currents from electrical companies to commercial buildings. They come in different types that serve various functions. Read on to learn what service entrance cables are and their primary characteristics.

    Service Entrance Cables

    There are two main types of service entrance cables: SER and SEU. SER cables are with a Style R reinforcement tape, and they typically deliver power from the service drop-down to the meter base to the distribution panel. SEU cables are most frequently used as panel feeders in branch circuit applications.

    According to the National Electric Code (NEC), service entrance cables are designed to be used for services. All service entrance cables are produced, tested, and marked according to UL 854 standards. Service entrance cables for underground use are UL Type USE or USE-2, and service entrance cables for aboveground use are UL Type SE, Style R or U. 

    Service Entrance Cable Characteristics

    Aboveground service entrance cables are either SER or SEU. They have a moisture-resistant and flame retardant covering that enables them to easily pull through framing members and wooden joists in commercial buildings. Installation and application of all service entrance cables are specified by NEC Article 338.

    Conductor Materials

    service entrance cables

    SEU and SER cables are manufactured with an AA-8000 series (ACM) electrical-conductor-grade aluminum alloy. Manufacturing underground UL Type USE and USE-2 cables that are not marked with any other type—such as RHH, RHW, or RHW-2—is done with an AA-8000 series (ACM) electrical-conductor-grade aluminum alloy or an EC-1350 grade aluminum alloy.

    SER and SEU cables have different anatomies that make them suitable for various parts of a project. For example, an SEU cable has a neutral conductor but lacks a ground conductor. Because ground conductors and neutral conductors are only joined at the point of service disconnect, SEU cables are only safe to use at the point of disconnect. On the other hand, SER cables have both neutral and ground conductors, which makes them safe to use after the service disconnect.

    Another difference between SER and SEU cables is their construction. SER cables are copper or aluminum wires reinforced with special Style R tape. SEU cables are Style U, which means they are unarmored and often used as panel feeders. Regardless of type, the installation of service entrance cables should always be done by a professional for safety reasons.

    Service Entrance Cables From Classic Wire and Cable

    Now that you have a good understanding of SER and SEU cables, the next step is to select a cable that fits your particular electrical project. With more than 200 years of combined cable and wire experience, Classic Wire and Cable’s experts specialize in serving electrical distributors.

    • Power wiring of airplanes

    From the late 1800s to the early 1900s, utility companies used aluminum wire in power grids for electrical transmission. The cost and weight advantages of the lightweight metal outweighed that of copper wiring.

    Today, aluminum wire is still the preferred material in power transmission and distribution applications. Since copper is a better conductor than aluminum, most home wiring projects and small applications use copper wires. However, in the 1960s, when the price of copper skyrocketed, aluminum wiring became the preferred choice for home wiring.

    Industrial Cable Types

    There are several industrial cable types to choose from, each having its own unique uses and advantages:

    Type MC Armored Cables

    Metal-clad (MC) armored cable constructions offer a cost-efficient alternative to traditional wire and pipe. This industrial cable type eliminates the need for an electrical conduit, thereby reducing the labor costs typically involved with installation.

    Contractors that use MC armored cable require:

    • Limited pulling equipment
    • Fewer reels
    • Less time setting up pulls
    • No specialty bending or cutting tools

    Key advantages of armored cable include:

    • Protection and durability. These cables provide the necessary protection and durability without needing an electrical conduit, costly offsets, elbows, and conduit couplings.
    • Corrosion resistance. Armored cable resists corrosion, making them suitable for locations exposed to excessive moisture.
    • Flexibility. The interlocked armor material is flexible, unlike continuously welded armor or other conduits, offering protection to the inner conductors. MC armored cable is also easy to install in complex, close-spaced bends.
    • No specialty tools. Installation does not require specialty cutting or bending tools.

    A variety of industries utilize aluminum cables due to their many benefits. Even though aluminum is much lighter than copper, it maintains the same conductivity properties, giving it a distinct advantage compared to other metals. When weight is a primary concern, as in load-bearing jobs, aluminum cables are preferred because of their lightweight yet durable design.

    When comparing copper cables to aluminum cables on a loading basis, aluminum offers several different advantages, including:

    • More cost-effective
    • Lighter in weight
    • Has the same conductivity

    SO Portable Cord CablesSO Portable Cord Cables (Copper)

    It is common practice to identify the properties of industrial wire and cable with a letter. With SO portable cord cables, the “S” stands for “Extra Hard Service,” and the “O” stands for “Oil Resistant.” This means that this type of industrial cable is ideal for applications requiring 600 volts or less, and its outer jacket is resistant to oil.
