    What is Dual Listed Conduit?

    ANACONDA SEALTITE® conduit and fittings are Dual Iisted with CSA and UL.Dual listed conduit and fittings meet Canadian Electrical Code and US National Electrical Code requirements for electrical safety and wiring protection.

    • Since the early 1950s, manufacturers in Canada and the USA needed to sell electrical equipment into both national markets. The manufacturers tried to save money by specifying and buying conduit that was either US or Canadian approved.
    • The 1956 product catalog for ANACONDA SEALTITE® offered two different conduit types, CSA and UA. Each conduit type met different national standards.
    • In the 1980s, manufacturers complained when border inspectors rejected or impounded electrical products not meeting national safety standards.
    • In 1985, manufacturers sought a conduit that met both standards, resulting in SEALTITE® Type DL (Dual Listed).
    • In 1995, ANACONDA SEALTITE® Type UA conduit met both national standards, so it is “Dual Listed.”
    • Since 1995, ANAMET Electrical has developed more conduit types that meet both standards but serve diverse needs.

    Does Dual Listing Confer an Advantage?

    CSA and UL symbols show compliance with national safety standards.

    US and Canadian manufacturers need conduit that meets both national standards. One product type complying with both standards saves money, avoids confusion and simplifies inventory.

    For projects built and products installed on either side of the Canadian-US border, Dual Listed products meet safety needs.

    ANACONDA SEALTITE® products such as liquid tight flexible conduit and corrosion resistant fittings comply with Canadian and US safety standards. Frequent factory inspection and product audits make sure products sustain compliance.

    • The UL mark and the CSA mark on liquid tight conduit show compliance.
    • The cULus mark on a liquid tight fitting shows compliance with the harmonized fitting standard.

    What are Some Differences in These Standards?

    Even though harmonization is pursued, there are significant differences between the standards. Features allowed by one standard are not supported by the other.

    • In 2024, the US safety code allows use of Stainless Steel core flexible conduit when a separate grounding conductor or bonding jumper is included in wiring. The Canadian standard does not allow stainless steel core flexible conduit to be installed.
    • The Canadian standard requires a lower temperature threshold and higher impact resistance to receive a “Heavy Duty” rating for conduit ½” diameter and larger. ANACONDA SEALTITE® conduit Types CW, UA, HTUA and ASUA show this unique approval with an HD mark on the conduit.
    • CSA approved conduit must meet at least the standard vertical flame test (FT1) which is similar to but different from the UL 360 standard flame test. Conduit is marked as FT1 if material passes the test. Conduit must stop burning within a minute after a flame is applied, self-extinguishing and not spreading fire.
    • The CSA standard requires conduit to have greater resistance to oil exposure than the UL standard, so conduit jacket material remains elastic after exposure to oil and heat.

    Are There Additional Standards?

    ANAMET Electrical developed “Dual Listed” conduit meeting both standards but serving diverse needs.

    • ANACONDA SEALTITE® Type FGUA UL listed Food Grade flexible conduit is CSA approved and meets NSF / ANSI 169 for special purpose food equipment or devices.
    • LFNC-B Type CNP non-metallic electrical conduit is UL and CSA approved, without a metal core. It is comparatively lightweight and bounces back from impact. SEALTITE® Nickel-plated Brass Type A fittings are approved for connecting Type CNP conduit.
    • SEALTITE® liquid tight fittings show harmonized safety approval with the cULus mark, showing compliance with both US and Canadian standards.
    • Type ASUA Anti-Static flexible conduit. It meets the Canadian “Heavy Duty” rating requirements and NEN-EN-IEC 600079-0 Section 26-13 anti-static surface resistivity requirement of less than one billion (thousand million) Ohms.
    • Type ZHUA Zero Halogen flexible conduit is UL and CSA approved, while it meets and exceeds other standards such as
      • ASTM-E162 (Flame spread)
      • ASTM-E662 (Smoke density)
      • Bombardier SMP-800C (Toxic gas generation)

  3. Where Do You Need Low Smoke and Halogen Free Conduit?

    Leave a Comment

    Due to fumes and toxic gas resulting from fire, thermoplastic covers on flexible, electrical conduit must be low smoke and Halogen free.

    Movies and TV episodes often show firefighters kitted with breathing apparatus to prevent smoke inhalation, which can weaken and kill first responders.

    Past experience with electrical fires motivated the development and requirement for low smoke and Halogen free conduit.

    ANAMET Electrical, Inc. developed UL listed conduit that meets and exceeds National Fire Prevention Association and other industrial standards for low smoke.

  5. Why Use Low Smoke and Halogen Free Conduit?

    Firefighter wearing personal protection equipment preventing smoke inhalation

    Protect People from Smoke Inhalation

    Avoid smoke inhalation. This can save your life. Most people do not have personal protection equipment in their homes that firefighters use to prevent smoke inhalation.

    So, regulations guiding construction and use of electrical equipment include prevention of smoke inhalation.

    Since November 6, 1896, the National Fire Protection Association (NFPA) has promoted fire safety. Every three years, NFPA publishes an improved National Electrical Code (NEC).

    An electrical fire may come from a single small source, but fire and smoke spread. Because fire can start from an electrical short circuit where broken wiring heats and ignites flammable material, the NEC recommends wiring protection. Electrical conduit is armor for wiring, preventing damage, accidental shock and fire. Since 1952, flexible, liquid tight, metal electrical conduit has been approved for use. The liquid tight jacket prevents water intrusion and electrical shock. Polyvinyl chloride (PVC) was extruded as a flexible jacket around metal conduit. However, material that is fire resistant at a low temperature can be ignited at higher temperatures, generating deadly smoke.

    Polyvinyl chloride (PVC), which does not ignite easily, was used as a flexible jacket on metal conduit. However, at high temperatures, burning PVC releases chlorine gas. This toxic Halogen irritates eyes, skin and lungs. When a person breathes in chlorine, the chlorine reacts with water to form acid that injures internal organs. This action disables people, preventing escape from fire. In 1988, devastating fires and smoke inhalation fatalities showed need for materials that are Low Smoke and Halogen Free.

    Low Smoke, Halogen Free Conduit Jackets Are Now Available

    Since 1985, ANAMET Electrical has created conduit jacketed with substitutes for PVC. Jacket compounds containing silicon, urethane and ethylene do not generate toxic Halogen gas. These compounds also have other attractive features such as increased resistance to acid or alkaline exposure.

    PVC is accepted as safe for installation in outdoor, exposed, buried or concealed locations. The NEC allows PVC jacketed conduit in Hazardous Locations. However, if you are specifying construction in tunnels, in confined spaces with little or no ventilation or near heat sources, consider a Low Smoke and Halogen Free ANACONDA SEALTITE® conduit from ANAMET Electrical, Inc.

  6. Why Use Electrical Conduit?

    Leave a Comment

    Why use conduit?

    Electrical shock is painful and can be injurious. Electrical conduit prevents contact with wiring and possible injury.

    What is electrical conduit?

    Electrical conduit is rigid or flexible tubing that protects electrical wiring. ANAMET Electrical, Inc. makes flexible electrical conduit conforming to “raceway of circular cross section made of helically wound, formed, interlocked metal strip” and “raceway of circular cross section having an outer liquid tight, non-metallic, sunlight resistant jacket over an inner metal flexible core.” These two definitions developed in the last 120 years in the NFPA 70®: National Electrical Code®.

    What are the advantages of electrical conduit?

    There are many ways to suffer injury or loss from poorly managed electricity. However, electrical conduit prevents contact between electrical wires and conductive or flammable material. Electrical conduit ensures a safe ground path for electricity and an armored route for electrical wiring and audio, video, telephone and internet cable.

    When buying a home or building an addition, an inspector usually examines construction to see if it is “up to Code,” so shortfalls or deviations from the safety code are known to the buyer and seller. This is because fire can be started by overcurrent demand and poorly installed, worn or aged wiring, when wiring overheats or causes a spark. Even if an older home previously passed an inspection, new standards may require new wiring or safety systems. Often, conduit is not replaced because new wires can be pulled through existing conduit to upgrade the electrical system. Large diameter electrical conduit provides options for future upgrade.

    Electrical conduit changes with technology and safety knowledge. ANAMET Electrical, Inc. made conduit to Code requirements for over 70 years. Founded in 1908 as American Metal Hose, ANAMET Electrical set standards for stripwound metal house used as flexible metal conduit. On April 18, 1949, Underwriter Laboratories listed SEALTITE®, the first liquid tight, flexible, electrical conduit, which is still in production at ANAMET Electrical, Inc.

    Both rigid and flexible electrical conduit can be seen on building sites, strung through walls and ceilings to protect wiring. “Flex” or “Greenfield” flexible metal conduit is approved for installation indoors in dry conditions. It protects wiring distributing power from a central grounding and bonding circuit-breaker box to outlets, appliances, controls and lights. Indoor conduit can be rigid or flexible, but they are not liquid tight, so water may degrade wiring.

    In contrast, liquid tight, flexible conduit has a metal or plastic core covered by thermosetting plastic. The plastic jacket protects wiring from liquids, temperature extremes and corrosive chemicals. The Code allows ground burial of liquid tight electrical conduit. Some utility companies recommend burial of electrical power lines inside plastic or plastic-jacketed conduit, due to the tree roots and their persistent intrusion into buried power lines. Burial of electrical power lines avoids use of power poles and pole-mounted transformers. Burial avoids wind, weather damage and weather-related power loss.

    Approved for outdoor use, liquid tight conduit protects wiring from the sun, wind and weather extremes. This conduit can be used to connect solar panels, air conditioners, heat pumps, wells, antennas, boathouses, garages, work sheds, greenhouses, hot tubs, swimming pools, irrigation controls, and outdoor sound and lighting systems.

    Why use Electrical conduit from ANAMET Electrical, Inc.?

    ANAMET Electrical persists in creating conduit that meets or exceeds safety requirements. Even if the conduit is not visible, choosing UL approved conduit ensures that safety is the first consideration to connect and protect wiring and cable. Electrical conduit fittings are designed to ensure a liquid tight connection. SEALTITE® electrical conduit fittings make sure water cannot enter the liquid tight conduit, ensuring safe connection of electrical power.

    When purchasing electrical conduit and fittings consider the conditions of use, future options and local code requirements. Save money and avoid unsafe conditions by working within the local code. If you need conduit in large quantities, contact us or request information today.

  7. What You Need to Know Before Buying Electrical Conduit

    Leave a Comment

    At ANAMET Electrical, Inc., we supply flexible electrical conduit to customers in various markets. As these components are designed to connect and protect electrical wiring, cables and other equipment, they play a critical role in many electrical and electronic applications. That’s why it is important to choose carefully when you need electrical conduit for your project. 

    This guide will explain what you need to know before buying conduit for your application. It provides an overview of what electrical conduit is, what types are available and what to consider before installing conduit.  

    What is Electrical Conduit?

    When electric lights were new to the world, existing pipes for gas light were used to route wiring to new electric light bulbs on existing light fixtures. The beginning National Fire Protection Association (1896) and  National Electrical Code (1897) preserved the idea of using pipe or tubing to protect electrified wiring. Electrical conduit is now tubing that electricians install to protect and route electrical wiring. It can be made from a variety of rigid or flexible materials, such as metal, PVC or thermosetting resin, depending on its intended use. Electrical conduit can be found in attics, basements, crawl spaces and on various interior and exterior spaces and surfaces. 

    What Types of Electrical Conduit Are Available?

    The National Electrical Code (NEC) defines the types of approved electrical conduit. This publication is frequently revised to keep up with innovative technology. States and municipalities decide how this Safety Code is applied or enforced. The requirements for electrical conduit are finely detailed. Electrical conduit can be rigid (metal, PVC or thermosetting resin) or flexible (metal (FMC), liquid tight metal (LFMC) and liquid tight non-metallic (LFNC). All conduit comes in a variety of sizes and there are limitations on how each type may be used.  

    • Rigid metal conduit is the heaviest and thickest conduit material option. It offers protection against mice and rats in basements, garages and similar environments. Due to its durability, it is commonly used in areas with extreme or harsh conditions. It is typically made from steel or aluminum, the latter of which is recommended for high-moisture environments since it resists corrosion. If the conduit must be installed around a corner, you may need a conduit bender, conduit couplings, offset fittings, and/or elbows.
    • Rigid PVC and thermosetting resin conduit are the lightest conduit material and the least expensive conduit option. It is used to protect electrical wiring from moisture and dirt. It is corrosion resistant, moisture resistant and non-conductive. It is used outdoors and below ground. It is commonly used for lawn irrigation controls and swimming pools. 
    • Flexible metal conduit (FMC) is called Greenfield or Flex in the building trades. It is recommended for dry locations indoors because it is not liquid tight. Its flexibility and lighter weight make it easier to install than rigid conduit. It is frequently used in the interior walls of houses and office buildings, cubicles and office ceilings (for connecting power to light fixtures). 
    • Liquid tight, flexible, metallic conduit (LFMC) is typically covered with a waterproof plastic coating to keep out moisture. Its flexibility enables it to be used in places with tight bends where rigid conduit would be hard to install. Typical uses include bridges, ground burial, paper mills, petrochemical facilities and water treatment plants.
    • Liquid tight, flexible, non-metallic conduit (LFNC) is suitable for use in dry, wet, or oily locations. It can be used in indoor or outdoor environments for industrial and commercial applications. Typical uses include ground burial, HVAC units, pools and spas. 

    What Should I Consider Before Installing Electrical Conduits?

    Click to Expand

    You will need to purchase conduit connectors (fittings) to install a conduit system. Fittings allow conduit to be connected to an electrical junction box.

    If you are buying conduit fittings from a supplier for the first time, you should keep in mind the following considerations to make sure you are getting the best solution for your needs: 

    • What are your local Safety Code requirements? Although the National Electrical Code describes conduit installation for operating conditions, local inspectors may provide guidance that can save money and time on installation, inspection and approval for wiring and conduit installation.
    • Are the fittings the right size? The diameter of the fitting must match the diameter of the selected conduit to provide a secure and liquid tight connection.
    • How long does the conduit and fittings need to last? If the conduit only needs to be used until the next remodeling project, you may shop for less durable, lower cost conduit and fitting options.
    • Are the conduit and fittings made of material appropriate for the installation conditions? Conduit is made of a variety of materials, both metal and non-metal, for resistance to intrusion, corrosion and liquids. Fittings should be equally durable. For liquid tight conduit, choose liquid tight fittings with seals and rings.
    • Does the supplier offer the type of fittings I need? The supplier you choose should offer the fittings matching the conduit you need for your project.
    • Will the supplier deliver the fittings by the time I need them? The supplier should be able to deliver the connectors to you with the conduit you purchase.  
    • Can the supplier provide a customized solution? If your project has distinctive features, you should look for a supplier that can provide conduit and fittings so you can be sure of safe and secure electrical connection to your specifications and standards.

    When To Use Liquid Tight Conduit

    An electrical conduit is a raceway that provides a protective pathway for electrical wires and cables to be run in any environment. There is a wide variety of electrical conduit to choose from and it’s important to choose the right one based on your application’s specifications and requirements.

    While manufacturers often suggest what kind of conduit to use, this blog will focus on the various applications for liquid tight flexible metal conduit, such as wet or moist environments, areas exposed to corrosive elements, settings prone to dust, dirt and various outdoor environments.

    Wet and Moist Environments

    Wet and Moist Environments

    Liquid tight conduit and fittings are specifically designed to keep wires and cables free of liquid or moisture. Humid, damp or wet environments that require cabling are ideal areas to use liquid tight conduit. Prime examples of these include car washes, water management facilities and food and beverage processing plants that must regularly hose down equipment. Liquid tight conduit will not only ensure the safety of the public and employees, but it also prolongs the life of cables and prevents electrical failures when used properly.

    When Cables May Be Exposed to Corrosive Elements

    When Cables May be Exposed To Corrosive Elements

    Liquid tight conduit is also an optimal choice for environments that are often exposed to corrosive elements. This type of conduit is not only capable of keeping out moisture, but it is also effective at sealing out harmful substances that can deteriorate wires and cables. This is highly beneficial for applications such as HVAC units, chemical facilities and other areas that are prone to corrosive substances.

    Various External Applications

    Various External Applications

    Any electrical installation that is exposed to the outside world can cause potential problems. UV rays and other outdoor elements can cause breakage and other types of damage. Using liquid tight flexible metal conduit protects cables and wires from sun exposure, extreme temperatures, moisture and other outdoor elements to prolong their lives and prevent damage.

    Dirty or Dusty Areas

    Dirty or Dusty Areas

    Dirt, dust and other tiny particles can cause short circuits and faulty equipment operation when wires and connections are not protected. For agricultural operations, textile plants, wood/pulp/paper mills and more, a sealed, liquid tight conduit can protect against dust and particulate infiltration.

    An added benefit of flexible metal conduit is their ability to bend. Compared to rigid conduit, flexible metal conduit bends easily, making it a suitable option for applications where rigid conduit would be too difficult to install.
