SER Cable

SER is a type of service entrance cable that brings power from electrical companies to buildings and other structures. At its core, SER is a round service electrical cable with up to four conductors and a bare ground wire. Aluminum SER cable is designed for above ground use in feeder panels and branch circuits. SER cable connects electrical power from the service drop or overhead service lines to a building’s electrical panel—also known as a main distribution panel or breaker panel.

DWC features high-quality and efficient SER cable for electricians, electrical contractors, and other professionals to use in residential, commercial, industrial, and utility settings to provide electrical power to lighting, heating, cooling, and other electrical systems.

SER Cable is often used for bringing power from utilities into homes.  

SER cable is composed of compact, stranded aluminum alloy conductors made of AA-8000 series. Individual conductors have XHHW-2 insulation with distinct colors. Insulated conductors are bundled together with a bare ground wire. The cable also features a flame-retardant binder tape made of fiberglass and sunlight-resistant markings printed on a gray polyvinyl chloride (PVC) material that is also flame-retardant.

Benefits of SER Cable

  1. Durability - It is resistant to moisture, UV rays, and other environmental factors that can cause damage.

  2. Code Compliance - Designed to meet strict safety standards set by industry organizations such as the National Electrical Code (NEC) and the National Fire Protection Association (NFPA).

  3. Ease of installation - SER can be run from the main electrical service to the electrical panel with minimal effort and is compatible with standard electrical fittings for simple integration with other parts of the electrical system.

  4. Versatility - Available in a range of sizes and configurations, making it suitable for use in a variety of electrical systems. Homeowners, business owners, and building managers appreciate SER for being reliable, safe, and cost-effective, while also meeting necessary safety requirements.

  5. Cost-effective: Compared to other types of electrical wiring, SER cable is relatively inexpensive, making it a cost-effective option for residential, commercial, industrial electrical systems regardless of size and complexity of your building.

  6. Reliability: Built to provide a reliable and safe electrical connection, which is essential for the smooth operation of commercial buildings.

Factors to consider when choosing SER Cable:

Gauge - A larger gauge number indicates a thinner conductor. Choose a gauge that is appropriate for the amount of current you will be carrying.

Voltage rating - Determines the maximum voltage your SER cable can safely handle. Choose a cable with an appropriate voltage rating for your application.

Insulation - Look for a cable that has high resistance to moisture, heat, and other environmental factors.

Conductivity - Look for a cable with a high conductivity rating, indicating it can carry electrical current with minimal resistance.

Length - Choose a cable that is long enough to meet your needs, but not so long that it is difficult to handle or install.

Flexibility - Consider how the cable will be installed and choose one flexible enough to be routed around obstacles and bent as needed.

Is it safe to install SER cable in residential and commercial buildings?

Yes, if it is done correctly by a licensed electrician who follows all relevant safety standards and codes.

How long does SER cable last in a residential or commercial building?

The lifespan of SER cable in a residential building depends on several factors, including environmental conditions, quality of materials, installation process, overloading, maintenance, and wear and tear due to age. With proper installation and maintenance, SER cable can last for many years.

Is it possible to upgrade my existing electrical wiring to SER cable in my residential building? Yes, it is possible to upgrade your existing electrical wiring to SER cable. This typically involves disconnecting the old wiring and installing the new SER cable to meet the electrical load requirements of your building. It is recommended to have a licensed electrician handle this process to ensure safety and compliance with local codes and regulations.

Can I use SER cable for sub-panels and other electrical components in my residential building? Yes, SER cable can be used for sub-panels and other electrical components in a residential building, as it is designed to be used with standard electrical fittings. It’s important to use the correct size and type of SER cable for each specific application to meet local codes and regulations. It is recommended to consult with a licensed electrician to determine the best solution for your specific needs.

What is the difference between SER cable used in residential and commercial buildings?

SER cable used in commercial buildings is typically larger and more robust than that used in residential buildings. This is because commercial buildings typically have higher electrical load requirements and more complex electrical systems.

Can SER cable be used for outdoor and indoor applications in a commercial building?

Yes, as it is designed to withstand harsh environmental conditions such as exposure to moisture and UV rays.

What type of SER cable is best suited for use in the utility industry?

In the utility industry, it is important to use high-quality, durable SER cable designed to withstand harsh environmental conditions, including exposure to high temperatures, moisture, and UV rays. XLPE (Cross-linked Polyethylene) or EPR (Ethylene Propylene Rubber) insulated SER cable is commonly used in the utility industry due to its durability and high resistance to moisture and heat.

How does SER cable enhance the safety of the electrical grid in the utility industry? SER cable reduces the risk of electrical failures and fires. The cable's durable insulation protects against electrical faults and helps to minimize downtime. Its flame-retardant properties reduce the risk of fires and improve the overall safety of the electrical grid.

How does the use of SER cable in the industrial and utility industries impact energy efficiency? SER cable helps to improve energy efficiency by reducing electrical resistance and improving conductivity of the electrical system. This helps minimize energy losses, improve the efficiency of the electrical grid, and reduce operating costs.

Is SER cable suitable for use in high temperature industrial environments?

Yes, SER cable is suitable for use in high temperature industrial environments due to its high resistance to heat and flame-retardant properties. This makes it a popular choice for use in industrial applications where high temperatures are a concern.

Can SER cable be used for both indoor and outdoor applications in an industrial building? Yes, SER cable is designed to withstand harsh environmental conditions and is rated for both indoor and outdoor use.

What type of SER cable is best suited for use in an industrial building?

In an industrial building, it is recommended to use XLPE (Cross-linked Polyethylene) or EPR (Ethylene Propylene Rubber) insulated SER cable due to its durability and high resistance to moisture and heat.

What is the maximum operating temperature for SER?

The maximum operating temperature for SER should not exceed 90°C in wet or dry locations. The voltage rating is 600 volts.
